NOTES: i) Maximum roof load widths are based on the support of a maximum total tile roof, framing and ceiling mass of 90 kg/m2. For guidance on roof and ceiling mass refer to Appendix B. ii) Where rafters or trusses are supported directly over studs or within 1.5 times the thickness of the top plate from the studs the top plate may be a minimum 35 mm deep. iii) Where plates support concentrated loads such as roof beams, struts, strutting beams, hanging beams, counter beams, combined strutting/hanging beams or girder trusses etc., the load shall be supported directly over a stud(s) designed to carry the load or the plate stiffened in accordance with Clause 6.2.2.3. iv) Plates may be trenched up to a maximum of 3 mm for studs. v) Multiple plates shall be nailed together as per Clause 2.5. vi) For design parameters refer to Figure 6.19. vii) Where wind uplift forces on rafters or trusses are taken to the substructure, bypassing the top plate, the top plate size may be determined using the tie-down spacing of “0” in the table.

NOTES: i) Maximum Lintel Spans are based on the support of a maximum total sheet roof, framing and ceiling mass of 40 kg/m2. For guidance on roof and ceiling mass refer to Appendix B. ii) For lintels supporting hanging beams, the area supported shall be taken as one half of the ceiling area supported by the lintel and the size determined from the sheet roof section. iii) Minimum bearing length = 35 mm at end supports. Subscript values indicate the minimum additional bearing length where required to be greater than 35 mm. iv) Multiple members nailed together as per Clause 2.3. v) For roof area supported refer Clause 2.6.5. vi) Lintels must be used in conjunction with top plates, ledgers and head trimmers. vii) When lintels are used to their maximun design limits, deflections of up to 10 mm (deadload) or 15mm (live load) may be expected. viii) The roof area supported by the lintel should only be that proportion of roof area contributing to the concentrated load on the lintel, ie the roof area input for a lintel supporting a strutting beam should be proportioned according to the area distributed to either end of the strutting beam.

NOTES: i) Maximum spans are based on the support of roof mass only for a coupled roof and the combined roof plus ceiling mass for a cathedral roof. For guidance on roof and ceiling mass refer to Appendix B. ii) Allowable overhangs are based on a maximum depth of birdsmouth of D/3. Refer Figure 7.28. iii) Where rafters are not birdsmouthed, the allowable overhang may be increased to 30% of the allowable single span for that member. Overhang shall not exceed 50% of actual backspan. iv) Overhang limits do not apply where rafter ends are tied back to wall frame. v) Overhang limits are only applicable where rafter ends are supported by a structural fascia board. Refer to Clause 7.3.13.2. vi) Multiple members shall be nailed together as per Clause 2.3. vii) For design parameters refer to Figures 7.26 and 7.27.

Standards Australia also supports excellence in design and innovation through the Australian Design Awards. For further information visit www.standards.org.au
Australian Standards® Committees of experts from industry, governments, consumers and other relevant sectors prepare Australian Standards. The requirements or recommendations contained in published Standards are a consensus of the views of representative interests and also take account of comments received from other sources. They reflect the latest scientific and industry experience. Australian Standards are kept under continuous review after publication and are updated regularly to take account of changing technology.
International Involvement Standards Australia is responsible for ensuring the Australian viewpoint is considered in the formulation of International Standards and that the latest international experience is incorporated in national Standards. This role is vital in assisting local industry to compete in international markets. Standards Australia represents Australia at both the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC).

NOTES: i) Maximum roof load widths are based on the support of a maximum total tile roof, framing and ceiling mass of 90 kg/m2. For guidance on roof and ceiling mass refer to Appendix B. ii) Where rafters or trusses are supported directly over studs or within 1.5 times the thickness of the top plate from the studs the top plate may be a minimum 35 mm deep. iii) Where plates support concentrated loads such as roof beams, struts, strutting beams, hanging beams, counter beams, combined strutting/hanging beams or girder trusses etc., the load shall be supported directly over a stud(s) designed to carry the load or the plate stiffened in accordance with Clause 6.2.2.3. iv) Plates may be trenched up to a maximum of 3 mm for studs. v) Multiple plates shall be nailed together as per Clause 2.5. vi) For design parameters refer to Figure 6.19. vii) Where wind uplift forces on rafters or trusses are taken to the substructure, bypassing the top plate, the top plate size may be determined using the tie-down spacing of “0” in the table.

NOTES: i) Maximum spans are based on the support of roof mass only for a coupled roof and the combined roof plus ceiling mass for a cathedral roof. For guidance on roof and ceiling mass refer to Appendix B. ii) Allowable overhangs are based on a maximum depth of birdsmouth of D/3. Refer Figure 7.28. iii) Where rafters are not birdsmouthed, the allowable overhang may be increased to 30% of the allowable single span for that member. Overhang shall not exceed 50% of actual backspan. iv) Overhang limits do not apply where rafter ends are tied back to wall frame. v) Overhang limits are only applicable where rafter ends are supported by a structural fascia board. Refer to Clause 7.3.13.2. vi) Multiple members shall be nailed together as per Clause 2.3. vii) For design parameters refer to Figures 7.26 and 7.27.

NOTES: i) Maximum roof load widths are based on the support of a maximum total sheet roof, framing and ceiling mass of 40 kg/m2. For guidance on roof and ceiling mass refer to Appendix B. ii) Where rafters or trusses are supported directly over studs or within 1.5 times the thickness of the top plate from the studs the top plate may be a minimum 35 mm deep. iii) Where plates support concentrated loads such as roof beams, struts, strutting beams, hanging beams, counter beams, combined strutting/hanging beams or girder trusses etc., the load shall be supported directly over a stud(s) designed to carry the load or the plate stiffened in accordance with Clause 6.2.2.3. iv) Plates may be trenched up to a maximum of 3 mm for studs. v) Multiple plates shall be nailed together as per Clause 2.5. vi) For design parameters refer to Figure 6.19. vii) Where wind uplift forces on rafters or trusses are taken to the substructure, bypassing the top plate, the top plate size may be determined using the tie-down spacing of “0” in the table.

NOTES: i) Maximum spans are based on the support of roof mass only up to a maximum sheet roof mass of 20 kg/m2 and tile roof mass of 60 kg/m2 . For guidance on roof and ceiling mass refer to Appendix B. The mass of rafters and underpurlins is accommodated in the span calculations. ii) Where the depth to breadth ratio exceeds 3:1 G.I. strapping or similar restraint to the top edge of the beam is to be provided at the strutting points and at beam ends. Refer to Clause 7.2.26. iii) Beam ends may be chamfered to a minimum depth of 100 mm or 1/3 of the beam depth, which ever is greater. iv) A minimum initial clearance of 25 mm shall be provided at mid-span between the underside of the strutting beam and the tops of ceiling joist, ceiling lining or ceiling battens as appropriate. v) Minimum bearing length = 70 mm at end supports. vi) Multiple members nailed together as per Clause 2.3. vii) For design parameters refer to Figure 7.24.

NOTES: i) Maximum spans are based on the support of roof mass only for a coupled roof and the combined roof plus ceiling mass for a cathedral roof. For guidance on roof and ceiling mass refer to Appendix B. ii) Allowable overhangs are based on a maximum depth of birdsmouth of D/3. Refer Figure 7.28. iii) Where rafters are not birdsmouthed, the allowable overhang may be increased to 30% of the allowable single span for that member. Overhang shall not exceed 50% of actual backspan. iv) Overhang limits do not apply where rafter ends are tied back to wall frame. v) Overhang limits are only applicable where rafter ends are supported by a structural fascia board. Refer to Clause 7.3.13.2. vi) Multiple members shall be nailed together as per Clause 2.3. vii) For design parameters refer to Figures 7.26 and 7.27.

Standards Australia Standards Australia develops Australian Standards® and other documents of public benefit and national interest. These Standards are developed through an open process of consultation and consensus, in which all interested parties are invited to participate. Through a Memorandum of Understanding with the Commonwealth Government, Standards Australia is recognized as Australia’s peak non-government national standards body. Standards Australia also supports excellence in design and innovation through the Australian Design Awards. For further information visit www.standards.org.au
Australian Standards® Committees of experts from industry, governments, consumers and other relevant sectors prepare Australian Standards. The requirements or recommendations contained in published Standards are a consensus of the views of representative interests and also take account of comments received from other sources. They reflect the latest scientific and industry experience. Australian Standards are kept under continuous review after publication and are updated regularly to take account of changing technology.
International Involvement Standards Australia is responsible for ensuring the Australian viewpoint is considered in the formulation of International Standards and that the latest international experience is incorporated in national Standards. This role is vital in assisting local industry to compete in international markets. Standards Australia represents Australia at both the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC).

3/45x90 NOTES: i) Maximum roof load widths are based on the support of a maximum total sheet roof, framing and ceiling mass of 40 kg/m2. For guidance on roof and ceiling mass refer to Appendix A. ii) Where rafters or trusses are supported directly over studs or within 1.5 times the thickness of the top plate from the studs the top plate may be a minimum 35 mm deep. iii) Where plates support concentrated loads such as roof beams, struts, strutting beams, hanging beams, counter beams, combined strutting/hanging beams or girder trusses etc., the load shall be supported directly over a stud(s) designed to carry the load or the plate stiffened in accordance with Clause 6.2.2.3. iv) Plates may be trenched up to a maximum of 3 mm for studs. v) Multiple plates shall be nailed together as per Clause 2.5. vi) For design parameters refer to Figure 6.19. vii) Where wind uplift forces on rafters or trusses are taken to the substructure, bypassing the top plate, the top plate size may be determined using the tie-down spacing of “0” in the table.

NOTES: i) Maximum spans are based on the support of roof mass only for a coupled roof and the combined roof plus ceiling mass for a cathedral roof. For guidance on roof and ceiling mass refer to Appendix A. ii) Allowable overhangs are based on a maximum depth of birdsmouth of D/3. Refer Figure 7.28. iii) Where rafters are not birdsmouthed, the allowable overhang may be increased to 30% of the allowable single span for that member. Overhang shall not exceed 50% of actual backspan. iv) Overhang limits do not apply where rafter ends are tied back to wall frame. v) Overhang limits are only applicable where rafter ends are supported by a structural fascia board. Refer to Clause 7.3.13.2. vi) Multiple members shall be nailed together as per Clause 2.3. vii) For design parameters refer to Figures 7.26 and 7.27.

NOTES: i) Maximum spans are based on the support of roof mass only for a coupled roof and the combined roof plus ceiling mass for a cathedral roof. For guidance on roof and ceiling mass refer to Appendix A. ii) Allowable overhangs are based on a maximum depth of birdsmouth of D/3. Refer Figure 7.28. iii) Where rafters are not birdsmouthed, the allowable overhang may be increased to 30% of the allowable single span for that member. Overhang shall not exceed 50% of actual backspan. iv) Overhang limits do not apply where rafter ends are tied back to wall frame. v) Overhang limits are only applicable where rafter ends are supported by a structural fascia board. Refer to Clause 7.3.13.2. vi) Multiple members shall be nailed together as per Clause 2.3. vii) For design parameters refer to Figures 7.26 and 7.27.

NOTES: i) Maximum spans are based on the support of roof mass only for a coupled roof and the combined roof plus ceiling mass for a cathedral roof. For guidance on roof and ceiling mass refer to Appendix A. ii) Allowable overhangs are based on a maximum depth of birdsmouth of D/3. Refer Figure 7.28. iii) Where rafters are not birdsmouthed, the allowable overhang may be increased to 30% of the allowable single span for that member. Overhang shall not exceed 50% of actual backspan. iv) Overhang limits do not apply where rafter ends are tied back to wall frame. v) Overhang limits are only applicable where rafter ends are supported by a structural fascia board. Refer to Clause 7.3.13.2. vi) Multiple members shall be nailed together as per Clause 2.3. vii) For design parameters refer to Figures 7.26 and 7.27.

NOTES: i) Maximum roof load widths are based on the support of a maximum total sheet roof, framing and ceiling mass of 40 kg/m2. For guidance on roof and ceiling mass refer to Appendix B. ii) Where rafters or trusses are supported directly over studs or within 1.5 times the thickness of the top plate from the studs the top plate may be a minimum 35 mm deep. iii) Where plates support concentrated loads such as roof beams, struts, strutting beams, hanging beams, counter beams, combined strutting/hanging beams or girder trusses etc., the load shall be supported directly over a stud(s) designed to carry the load or the plate stiffened in accordance with Clause 6.2.2.3. iv) Plates may be trenched up to a maximum of 3 mm for studs. v) Multiple plates shall be nailed together as per Clause 2.5. vi) For design parameters refer to Figure 6.19. vii) Where wind uplift forces on rafters or trusses are taken to the substructure, bypassing the top plate, the top plate size may be determined using the tie-down spacing of “0” in the table.

NOTES: i) Maximum spans are based on the support of roof mass only for a coupled roof and the combined roof plus ceiling mass for a cathedral roof. For guidance on roof and ceiling mass refer to Appendix B. ii) Allowable overhangs are based on a maximum depth of birdsmouth of D/3. Refer Figure 7.28. iii) Where rafters are not birdsmouthed, the allowable overhang may be increased to 30% of the allowable single span for that member. Overhang shall not exceed 50% of actual backspan. iv) Overhang limits do not apply where rafter ends are tied back to wall frame. v) Overhang limits are only applicable where rafter ends are supported by a structural fascia board. Refer to Clause 7.3.13.2. vi) Multiple members shall be nailed together as per Clause 2.3. vii) For design parameters refer to Figures 7.26 and 7.27.

NOTES: i) Maximum spans are based on the support of roof mass only up to a maximum sheet roof mass of 20 kg/m2 and tile roof mass of 60 kg/m2. For guidance on roof and ceiling mass refer to Appendix B. The mass of rafters and underpurlins is accommodated in the span calculations. ii) Where the depth to breadth ratio exceeds 3:1 G.I. strapping or similar restraint to the top edge of the beam is to be provided at the strutting points and at beam ends. Refer to Clause 7.2.26. iii) Beam ends may be chamfered to a minimum depth of 100 mm or 1/3 of the beam depth, which ever is greater. iv) A minimum initial clearance of 25 mm shall be provided at mid-span between the underside of the strutting beam and the tops of ceiling joist, ceiling lining or ceiling battens as appropriate. v) Minimum bearing length = 70 mm at end supports. vi) Multiple members nailed together as per Clause 2.3. vii) For design parameters refer to Figure 7.24.

NOTES: i) Maximum spans are based on the support of roof mass only for a coupled roof and the combined roof plus ceiling mass for a cathedral roof. For guidance on roof and ceiling mass refer to Appendix B. ii) Allowable overhangs are based on a maximum depth of birdsmouth of D/3. Refer Figure 7.28. iii) Where rafters are not birdsmouthed, the allowable overhang may be increased to 30% of the allowable single span for that member. Overhang shall not exceed 50% of actual backspan. iv) Overhang limits do not apply where rafter ends are tied back to wall frame. v) Overhang limits are only applicable where rafter ends are supported by a structural fascia board. Refer to Clause 7.3.13.2. vi) Multiple members shall be nailed together as per Clause 2.3. vii) For design parameters refer to Figures 7.26 and 7.27.

To maintain their currency, all Standards are periodically reviewed, and new editions are published. Between editions, amendments may be issued. Standards may also be withdrawn. It is important that readers assure themselves they are using a current Standard, which should include any amendments that may have been published since the Standard was published. Detailed information about Australian Standards, drafts, amendments and new projects can be found by visiting www.standards.org.au Standards Australia welcomes suggestions for improvements, and encourages readers to notify us immediately of any apparent inaccuracies or ambiguities.

NOTES: i) Maximum roof load widths are based on the support of a maximum total tile roof, framing and ceiling mass of 90 kg/m2. For guidance on roof and ceiling mass refer to Appendix B. ii) Where rafters or trusses are supported directly over studs or within 1.5 times the thickness of the top plate from the studs the top plate may be a minimum 35 mm deep. iii) Where plates support concentrated loads such as roof beams, struts, strutting beams, hanging beams, counter beams, combined strutting/hanging beams or girder trusses etc., the load shall be supported directly over a stud(s) designed to carry the load or the plate stiffened in accordance with Clause 6.2.2.3. iv) Plates may be trenched up to a maximum of 3 mm for studs. v) Multiple plates shall be nailed together as per Clause 2.5. vi) For design parameters refer to Figure 6.19. vii) Where wind uplift forces on rafters or trusses are taken to the substructure, bypassing the top plate, the top plate size may be determined using the tie-down spacing of “0” in the table.

NOTES: i) Maximum Lintel Spans are based on the support of a maximum total sheet roof, framing and ceiling mass of 40 kg/m2. For guidance on roof and ceiling mass refer to Appendix B. ii) For lintels supporting hanging beams, the area supported shall be taken as one half of the ceiling area supported by the lintel and the size determined from the sheet roof section. iii) Minimum bearing length = 35 mm at end supports. Subscript values indicate the minimum additional bearing length where required to be greater than 35 mm. iv) Multiple members nailed together as per Clause 2.3. v) For roof area supported refer Clause 2.6.5. vi) Lintels must be used in conjunction with top plates, ledgers and head trimmers. vii) When lintels are used to their maximun design limits, deflections of up to 10 mm (deadload) or 15mm (live load) may be expected. viii) The roof area supported by the lintel should only be that proportion of roof area contributing to the concentrated load on the lintel, ie the roof area input for a lintel supporting a strutting beam should be proportioned according to the area distributed to either end of the strutting beam.

NOTES: i) Maximum spans are based on the support of roof mass only for a coupled roof and the combined roof plus ceiling mass for a cathedral roof. For guidance on roof and ceiling mass refer to Appendix B. ii) Allowable overhangs are based on a maximum depth of birdsmouth of D/3. Refer Figure 7.28. iii) Where rafters are not birdsmouthed, the allowable overhang may be increased to 30% of the allowable single span for that member. Overhang shall not exceed 50% of actual backspan. iv) Overhang limits do not apply where rafter ends are tied back to wall frame. v) Overhang limits are only applicable where rafter ends are supported by a structural fascia board. Refer to Clause 7.3.13.2. vi) Multiple members shall be nailed together as per Clause 2.3. vii) For design parameters refer to Figures 7.26 and 7.27.

NOTES: i) Maximum spans are based on the support of roof mass only for a coupled roof and the combined roof plus ceiling mass for a cathedral roof. For guidance on roof and ceiling mass refer to Appendix B. ii) Allowable overhangs are based on a maximum depth of birdsmouth of D/3. Refer Figure 7.28. iii) Where rafters are not birdsmouthed, the allowable overhang may be increased to 30% of the allowable single span for that member. Overhang shall not exceed 50% of actual backspan. iv) Overhang limits do not apply where rafter ends are tied back to wall frame. v) Overhang limits are only applicable where rafter ends are supported by a structural fascia board. Refer to Clause 7.3.13.2. vi) Multiple members shall be nailed together as per Clause 2.3. vii) For design parameters refer to Figures 7.26 and 7.27.

NOTES: i) Maximum floor joist spans supporting roof loads are based on the support of a maximum total sheet roof, framing and ceiling mass of 40 kg/m2 , maximum total tile roof, framing and ceiling mass of 90 kg/m2 and a maximum flooring mass of 40 kg/m2. ii) A Roof Load Width of ”0” shall be used for floor joist not supporting roof loads. iii) The sizes given in this table are not suitable where heavy point loads, except those allowed by Clause 4.3.2.4, are supported within the joist span. iv) For the lower storey of two storey construction, floor joists shall not support roof or upper floor loads within their span. v) Where the ends of joist do not support roof loads, the joist may cantilever 25% of the allowable single span for size used, except that the cantilever shall not exceed 50% of the actual backspan. vi) Joists crippled over supports shall be considered as single span joists. Refer Clause 2.7.5.4. vii) Where joist size D/B > 4 restraint may be required. Refer Clause 4.2.2.3. viii) For design parameters refer to Figure 4.9.

NOTES: i) Maximum roof load widths are based on the support of a maximum total tile roof, framing and ceiling mass of 90 kg/m2. For guidance on roof and ceiling mass refer to Appendix B. ii) Where rafters or trusses are supported directly over studs or within 1.5 times the thickness of the top plate from the studs the top plate may be a minimum 35 mm deep. iii) Where plates support concentrated loads such as roof beams, struts, strutting beams, hanging beams, counter beams, combined strutting/hanging beams or girder trusses etc., the load shall be supported directly over a stud(s) designed to carry the load or the plate stiffened in accordance with Clause 6.2.2.3. iv) Plates may be trenched up to a maximum of 3 mm for studs. v) Multiple plates shall be nailed together as per Clause 2.5. vi) For design parameters refer to Figure 6.19. vii) Where wind uplift forces on rafters or trusses are taken to the substructure, bypassing the top plate, the top plate size may be determined using the tie-down spacing of “0” in the table.

For guidance on roof and ceiling mass refer to Appendix B. ii) For lintels supporting hanging beams, the area supported shall be taken as one half of the ceiling area supported by the lintel and the size determined from the sheet roof section. iii) Minimum bearing length = 35 mm at end supports. Subscript values indicate the minimum additional bearing length where required to be greater than 35 mm. iv) Multiple members nailed together as per Clause 2.3. v) For roof area supported refer Clause 2.6.5. vi) Lintels must be used in conjunction with top plates, ledgers and head trimmers. vii) When lintels are used to their maximun design limits, deflections of up to 10 mm (deadload) or 15mm (live load) may be expected. viii) The roof area supported by the lintel should only be that proportion of roof area contributing to the concentrated load on the lintel, ie the roof area input for a lintel supporting a strutting beam should be proportioned according to the area distributed to either end of the strutting beam.

NOTES: i) Maximum spans are based on the support of roof mass only for a coupled roof and the combined roof plus ceiling mass for a cathedral roof. For guidance on roof and ceiling mass refer to Appendix B. ii) Allowable overhangs are based on a maximum depth of birdsmouth of D/3. Refer Figure 7.28. iii) Where rafters are not birdsmouthed, the allowable overhang may be increased to 30% of the allowable single span for that member. Overhang shall not exceed 50% of actual backspan. iv) Overhang limits do not apply where rafter ends are tied back to wall frame. v) Overhang limits are only applicable where rafter ends are supported by a structural fascia board. Refer to Clause 7.3.13.2. vi) Multiple members shall be nailed together as per Clause 2.3. vii) For design parameters refer to Figures 7.26 and 7.27.

NOTES: i) Maximum floor joist spans supporting roof loads are based on the support of a maximum total sheet roof, framing and ceiling mass of 40 kg/m2 , maximum total tile roof, framing and ceiling mass of 90 kg/m2 and a maximum flooring mass of 40 kg/m2. ii) A Roof Load Width of ”0” shall be used for floor joist not supporting roof loads. iii) The sizes given in this table are not suitable where heavy point loads, except those allowed by Clause 4.3.2.4, are supported within the joist span. iv) For the lower storey of two storey construction, floor joists shall not support roof or upper floor loads within their span. v) Where the ends of joist do not support roof loads, the joist may cantilever 25% of the allowable single span for size used, except that the cantilever shall not exceed 50% of the actual backspan. vi) Joists crippled over supports shall be considered as single span joists. Refer Clause 2.7.5.4. vii) Where joist size D/B > 4 restraint may be required. Refer Clause 4.2.2.3. viii) For design parameters refer to Figure 4.9.

NOTES: i) Maximum roof load widths are based on the support of a maximum total tile roof, framing and ceiling mass of 90 kg/m2. For guidance on roof and ceiling mass refer to Appendix B. ii) Where rafters or trusses are supported directly over studs or within 1.5 times the thickness of the top plate from the studs the top plate may be a minimum 35 mm deep. iii) Where plates support concentrated loads such as roof beams, struts, strutting beams, hanging beams, counter beams, combined strutting/hanging beams or girder trusses etc., the load shall be supported directly over a stud(s) designed to carry the load or the plate stiffened in accordance with Clause 6.2.2.3. iv) Plates may be trenched up to a maximum of 3 mm for studs. v) Multiple plates shall be nailed together as per Clause 2.5. vi) For design parameters refer to Figure 6.19. vii) Where wind uplift forces on rafters or trusses are taken to the substructure, bypassing the top plate, the top plate size may be determined using the tie-down spacing of “0” in the table.

Subscript values indicate the minimum additional bearing length where required to be greater than 35 mm. iv) Multiple members nailed together as per Clause 2.3. v) For roof area supported refer Clause 2.6.5. vi) Lintels must be used in conjunction with top plates, ledgers and head trimmers. vii) When lintels are used to their maximun design limits, deflections of up to 10 mm (deadload) or 15mm (live load) may be expected. viii) The roof area supported by the lintel should only be that proportion of roof area contributing to the concentrated load on the lintel, ie the roof area input for a lintel supporting a strutting beam should be proportioned according to the area distributed to either end of the strutting beam.

NOTES: i) Maximum spans are based on the support of roof mass only for a coupled roof and the combined roof plus ceiling mass for a cathedral roof. For guidance on roof and ceiling mass refer to Appendix B. ii) Allowable overhangs are based on a maximum depth of birdsmouth of D/3. Refer Figure 7.28. iii) Where rafters are not birdsmouthed, the allowable overhang may be increased to 30% of the allowable single span for that member. Overhang shall not exceed 50% of actual backspan. iv) Overhang limits do not apply where rafter ends are tied back to wall frame. v) Overhang limits are only applicable where rafter ends are supported by a structural fascia board. Refer to Clause 7.3.13.2. vi) Multiple members shall be nailed together as per Clause 2.3. vii) For design parameters refer to Figures 7.26 and 7.27.

NOTES: i) Maximum floor joist spans supporting roof loads are based on the support of a maximum total sheet roof, framing and ceiling mass of 40 kg/m2 , maximum total tile roof, framing and ceiling mass of 90 kg/m2 and a maximum flooring mass of 40 kg/m2. ii) A Roof Load Width of ”0” shall be used for floor joist not supporting roof loads. iii) The sizes given in this table are not suitable where heavy point loads, except those allowed by Clause 4.3.2.4, are supported within the joist span. iv) For the lower storey of two storey construction, floor joists shall not support roof or upper floor loads within their span. v) Where the ends of joist do not support roof loads, the joist may cantilever 25% of the allowable single span for size used, except that the cantilever shall not exceed 50% of the actual backspan. vi) Joists crippled over supports shall be considered as single span joists. Refer Clause 2.7.5.4. vii) Where joist size D/B > 4 restraint may be required. Refer Clause 4.2.2.3. viii) For design parameters refer to Figure 4.9.

NOTES: i) Maximum roof load widths are based on the support of a maximum total tile roof, framing and ceiling mass of 90 kg/m2. For guidance on roof and ceiling mass refer to Appendix B. ii) Where rafters or trusses are supported directly over studs or within 1.5 times the thickness of the top plate from the studs the top plate may be a minimum 35 mm deep. iii) Where plates support concentrated loads such as roof beams, struts, strutting beams, hanging beams, counter beams, combined strutting/hanging beams or girder trusses etc., the load shall be supported directly over a stud(s) designed to carry the load or the plate stiffened in accordance with Clause 6.2.2.3. iv) Plates may be trenched up to a maximum of 3 mm for studs. v) Multiple plates shall be nailed together as per Clause 2.5. vi) For design parameters refer to Figure 6.19. vii) Where wind uplift forces on rafters or trusses are taken to the substructure, bypassing the top plate, the top plate size may be determined using the tie-down spacing of “0” in the table.

NOTES: i) Maximum Lintel Spans are based on the support of a maximum total sheet roof, framing and ceiling mass of 40 kg/m2. For guidance on roof and ceiling mass refer to Appendix B. ii) For lintels supporting hanging beams, the area supported shall be taken as one half of the ceiling area supported by the lintel and the size determined from the sheet roof section. iii) Minimum bearing length = 35 mm at end supports. Subscript values indicate the minimum additional bearing length where required to be greater than 35 mm. iv) Multiple members nailed together as per Clause 2.3. v) For roof area supported refer Clause 2.6.5. vi) Lintels must be used in conjunction with top plates, ledgers and head trimmers. vii) When lintels are used to their maximun design limits, deflections of up to 10 mm (deadload) or 15mm (live load) may be expected. viii) The roof area supported by the lintel should only be that proportion of roof area contributing to the concentrated load on the lintel, ie the roof area input for a lintel supporting a strutting beam should be proportioned according to the area distributed to either end of the strutting beam.

NOTES: i) Maximum spans are based on the support of roof mass only for a coupled roof and the combined roof plus ceiling mass for a cathedral roof. For guidance on roof and ceiling mass refer to Appendix B. ii) Allowable overhangs are based on a maximum depth of birdsmouth of D/3. Refer Figure 7.28. iii) Where rafters are not birdsmouthed, the allowable overhang may be increased to 30% of the allowable single span for that member. Overhang shall not exceed 50% of actual backspan. iv) Overhang limits do not apply where rafter ends are tied back to wall frame. v) Overhang limits are only applicable where rafter ends are supported by a structural fascia board. Refer to Clause 7.3.13.2. vi) Multiple members shall be nailed together as per Clause 2.3. vii) For design parameters refer to Figures 7.26 and 7.27.

These Standards are developed through an open process of consultation and consensus, in which all interested parties are invited to participate. Through a Memorandum of Understanding with the Commonwealth Government, Standards Australia is recognized as Australia’s peak non-government national standards body. Standards Australia also supports excellence in design and innovation through the Australian Design Awards. For further information visit www.standards.org.au
Australian Standards® Committees of experts from industry, governments, consumers and other relevant sectors prepare Australian Standards. The requirements or recommendations contained in published Standards are a consensus of the views of representative interests and also take account of comments received from other sources. They reflect the latest scientific and industry experience. Australian Standards are kept under continuous review after publication and are updated regularly to take account of changing technology.
International Involvement Standards Australia is responsible for ensuring the Australian viewpoint is considered in the formulation of International Standards and that the latest international experience is incorporated in national Standards. This role is vital in assisting local industry to compete in international markets. Standards Australia represents Australia at both the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC).

NOTES: i) Maximum roof load widths are based on the support of a maximum total tile roof, framing and ceiling mass of 90 kg/m2. For guidance on roof and ceiling mass refer to Appendix B. ii) Where rafters or trusses are supported directly over studs or within 1.5 times the thickness of the top plate from the studs the top plate may be a minimum 35 mm deep. iii) Where plates support concentrated loads such as roof beams, struts, strutting beams, hanging beams, counter beams, combined strutting/hanging beams or girder trusses etc., the load shall be supported directly over a stud(s) designed to carry the load or the plate stiffened in accordance with Clause 6.2.2.3. iv) Plates may be trenched up to a maximum of 3 mm for studs. v) Multiple plates shall be nailed together as per Clause 2.5. vi) For design parameters refer to Figure 6.19. vii) Where wind uplift forces on rafters or trusses are taken to the substructure, bypassing the top plate, the top plate size may be determined using the tie-down spacing of “0” in the table.

NOTES: i) Maximum Lintel Spans are based on the support of a maximum total sheet roof, framing and ceiling mass of 40 kg/m2. For guidance on roof and ceiling mass refer to Appendix B. ii) For lintels supporting hanging beams, the area supported shall be taken as one half of the ceiling area supported by the lintel and the size determined from the sheet roof section. iii) Minimum bearing length = 35 mm at end supports. Subscript values indicate the minimum additional bearing length where required to be greater than 35 mm. iv) Multiple members nailed together as per Clause 2.3. v) For roof area supported refer Clause 2.6.5. vi) Lintels must be used in conjunction with top plates, ledgers and head trimmers. vii) When lintels are used to their maximun design limits, deflections of up to 10 mm (deadload) or 15mm (live load) may be expected. viii) The roof area supported by the lintel should only be that proportion of roof area contributing to the concentrated load on the lintel, ie the roof area input for a lintel supporting a strutting beam should be proportioned according to the area distributed to either end of the strutting beam.

NOTES: i) Maximum spans are based on the support of roof mass only for a coupled roof and the combined roof plus ceiling mass for a cathedral roof. For guidance on roof and ceiling mass refer to Appendix B. ii) Allowable overhangs are based on a maximum depth of birdsmouth of D/3. Refer Figure 7.28. iii) Where rafters are not birdsmouthed, the allowable overhang may be increased to 30% of the allowable single span for that member. Overhang shall not exceed 50% of actual backspan. iv) Overhang limits do not apply where rafter ends are tied back to wall frame. v) Overhang limits are only applicable where rafter ends are supported by a structural fascia board. Refer to Clause 7.3.13.2. vi) Multiple members shall be nailed together as per Clause 2.3. vii) For design parameters refer to Figures 7.26 and 7.27.

NOTES: i) Maximum roof load widths are based on the support of a maximum total tile roof, framing and ceiling mass of 90 kg/m2. For guidance on roof and ceiling mass refer to Appendix B. ii) Where rafters or trusses are supported directly over studs or within 1.5 times the thickness of the top plate from the studs the top plate may be a minimum 35 mm deep. iii) Where plates support concentrated loads such as roof beams, struts, strutting beams, hanging beams, counter beams, combined strutting/hanging beams or girder trusses etc., the load shall be supported directly over a stud(s) designed to carry the load or the plate stiffened in accordance with Clause 6.2.2.3. iv) Plates may be trenched up to a maximum of 3 mm for studs. v) Multiple plates shall be nailed together as per Clause 2.5. vi) For design parameters refer to Figure 6.19. vii) Where wind uplift forces on rafters or trusses are taken to the substructure, bypassing the top plate, the top plate size may be determined using the tie-down spacing of “0” in the table.

NOTES: i) Maximum Lintel Spans are based on the support of a maximum total sheet roof, framing and ceiling mass of 40 kg/m2. For guidance on roof and ceiling mass refer to Appendix B. ii) For lintels supporting hanging beams, the area supported shall be taken as one half of the ceiling area supported by the lintel and the size determined from the sheet roof section. iii) Minimum bearing length = 35 mm at end supports. Subscript values indicate the minimum additional bearing length where required to be greater than 35 mm. iv) Multiple members nailed together as per Clause 2.3. v) For roof area supported refer Clause 2.6.5. vi) Lintels must be used in conjunction with top plates, ledgers and head trimmers. vii) When lintels are used to their maximun design limits, deflections of up to 10 mm (deadload) or 15mm (live load) may be expected. viii) The roof area supported by the lintel should only be that proportion of roof area contributing to the concentrated load on the lintel, ie the roof area input for a lintel supporting a strutting beam should be proportioned according to the area distributed to either end of the strutting beam.

NOTES: i) Maximum spans are based on the support of roof mass only for a coupled roof and the combined roof plus ceiling mass for a cathedral roof. For guidance on roof and ceiling mass refer to Appendix B. ii) Allowable overhangs are based on a maximum depth of birdsmouth of D/3. Refer Figure 7.28. iii) Where rafters are not birdsmouthed, the allowable overhang may be increased to 30% of the allowable single span for that member. Overhang shall not exceed 50% of actual backspan. iv) Overhang limits do not apply where rafter ends are tied back to wall frame. v) Overhang limits are only applicable where rafter ends are supported by a structural fascia board. Refer to Clause 7.3.13.2. vi) Multiple members shall be nailed together as per Clause 2.3. vii) For design parameters refer to Figures 7.26 and 7.27.

NOTES: i) Maximum spans are based on the support of roof mass only for a coupled roof and the combined roof plus ceiling mass for a cathedral roof. For guidance on roof and ceiling mass refer to Appendix B. ii) Allowable overhangs are based on a maximum depth of birdsmouth of D/3. Refer Figure 7.28. iii) Where rafters are not birdsmouthed, the allowable overhang may be increased to 30% of the allowable single span for that member. Overhang shall not exceed 50% of actual backspan. iv) Overhang limits do not apply where rafter ends are tied back to wall frame. v) Overhang limits are only applicable where rafter ends are supported by a structural fascia board. Refer to Clause 7.3.13.2. vi) Multiple members shall be nailed together as per Clause 2.3. vii) For design parameters refer to Figures 7.26 and 7.27.

NOTES: i) Maximum roof load widths are based on the support of a maximum total tile roof, framing and ceiling mass of 90 kg/m2. For guidance on roof and ceiling mass refer to Appendix B. ii) Where rafters or trusses are supported directly over studs or within 1.5 times the thickness of the top plate from the studs the top plate may be a minimum 35 mm deep. iii) Where plates support concentrated loads such as roof beams, struts, strutting beams, hanging beams, counter beams, combined strutting/hanging beams or girder trusses etc., the load shall be supported directly over a stud(s) designed to carry the load or the plate stiffened in accordance with Clause 6.2.2.3. iv) Plates may be trenched up to a maximum of 3 mm for studs. v) Multiple plates shall be nailed together as per Clause 2.5. vi) For design parameters refer to Figure 6.19. vii) Where wind uplift forces on rafters or trusses are taken to the substructure, bypassing the top plate, the top plate size may be determined using the tie-down spacing of “0” in the table.

NOTES: i) Maximum Lintel Spans are based on the support of a maximum total sheet roof, framing and ceiling mass of 40 kg/m2. For guidance on roof and ceiling mass refer to Appendix B. ii) For lintels supporting hanging beams, the area supported shall be taken as one half of the ceiling area supported by the lintel and the size determined from the sheet roof section. iii) Minimum bearing length = 35 mm at end supports. Subscript values indicate the minimum additional bearing length where required to be greater than 35 mm. iv) Multiple members nailed together as per Clause 2.3. v) For roof area supported refer Clause 2.6.5. vi) Lintels must be used in conjunction with top plates, ledgers and head trimmers. vii) When lintels are used to their maximun design limits, deflections of up to 10 mm (deadload) or 15mm (live load) may be expected. viii) The roof area supported by the lintel should only be that proportion of roof area contributing to the concentrated load on the lintel, ie the roof area input for a lintel supporting a strutting beam should be proportioned according to the area distributed to either end of the strutting beam.

NOTES: i) Maximum spans are based on the support of roof mass only for a coupled roof and the combined roof plus ceiling mass for a cathedral roof. For guidance on roof and ceiling mass refer to Appendix B. ii) Allowable overhangs are based on a maximum depth of birdsmouth of D/3. Refer Figure 7.28. iii) Where rafters are not birdsmouthed, the allowable overhang may be increased to 30% of the allowable single span for that member. Overhang shall not exceed 50% of actual backspan. iv) Overhang limits do not apply where rafter ends are tied back to wall frame. v) Overhang limits are only applicable where rafter ends are supported by a structural fascia board. Refer to Clause 7.3.13.2. vi) Multiple members shall be nailed together as per Clause 2.3. vii) For design parameters refer to Figures 7.26 and 7.27.

These Standards are developed through an open process of consultation and consensus, in which all interested parties are invited to participate. Through a Memorandum of Understanding with the Commonwealth Government, Standards Australia is recognized as Australia’s peak non-government national standards body. Standards Australia also supports excellence in design and innovation through the Australian Design Awards. For further information visit www.standards.org.au
Australian Standards® Committees of experts from industry, governments, consumers and other relevant sectors prepare Australian Standards. The requirements or recommendations contained in published Standards are a consensus of the views of representative interests and also take account of comments received from other sources. They reflect the latest scientific and industry experience. Australian Standards are kept under continuous review after publication and are updated regularly to take account of changing technology.
International Involvement Standards Australia is responsible for ensuring the Australian viewpoint is considered in the formulation of International Standards and that the latest international experience is incorporated in national Standards. This role is vital in assisting local industry to compete in international markets. Standards Australia represents Australia at both the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC).

NOTES: i) Maximum roof load widths are based on the support of a maximum total tile roof, framing and ceiling mass of 90 kg/m2. For guidance on roof and ceiling mass refer to Appendix B. ii) Where rafters or trusses are supported directly over studs or within 1.5 times the thickness of the top plate from the studs the top plate may be a minimum 35 mm deep. iii) Where plates support concentrated loads such as roof beams, struts, strutting beams, hanging beams, counter beams, combined strutting/hanging beams or girder trusses etc., the load shall be supported directly over a stud(s) designed to carry the load or the plate stiffened in accordance with Clause 6.2.2.3. iv) Plates may be trenched up to a maximum of 3 mm for studs. v) Multiple plates shall be nailed together as per Clause 2.5. vi) For design parameters refer to Figure 6.19. vii) Where wind uplift forces on rafters or trusses are taken to the substructure, bypassing the top plate, the top plate size may be determined using the tie-down spacing of “0” in the table.

NOTES: i) Maximum Lintel Spans are based on the support of a maximum total sheet roof, framing and ceiling mass of 40 kg/m2. For guidance on roof and ceiling mass refer to Appendix B. ii) For lintels supporting hanging beams, the area supported shall be taken as one half of the ceiling area supported by the lintel and the size determined from the sheet roof section. iii) Minimum bearing length = 35 mm at end supports. Subscript values indicate the minimum additional bearing length where required to be greater than 35 mm. iv) Multiple members nailed together as per Clause 2.3. v) For roof area supported refer Clause 2.6.5. vi) Lintels must be used in conjunction with top plates, ledgers and head trimmers. vii) When lintels are used to their maximun design limits, deflections of up to 10 mm (deadload) or 15mm (live load) may be expected. viii) The roof area supported by the lintel should only be that proportion of roof area contributing to the concentrated load on the lintel, ie the roof area input for a lintel supporting a strutting beam should be proportioned according to the area distributed to either end of the strutting beam.

NOTES: i) Maximum spans are based on the support of roof mass only for a coupled roof and the combined roof plus ceiling mass for a cathedral roof. For guidance on roof and ceiling mass refer to Appendix B. ii) Allowable overhangs are based on a maximum depth of birdsmouth of D/3. Refer Figure 7.28. iii) Where rafters are not birdsmouthed, the allowable overhang may be increased to 30% of the allowable single span for that member. Overhang shall not exceed 50% of actual backspan. iv) Overhang limits do not apply where rafter ends are tied back to wall frame. v) Overhang limits are only applicable where rafter ends are supported by a structural fascia board. Refer to Clause 7.3.13.2. vi) Multiple members shall be nailed together as per Clause 2.3. vii) For design parameters refer to Figures 7.26 and 7.27.

NOTES: i) Maximum roof load widths are based on the support of a maximum total sheet roof, framing and ceiling mass of 40 kg/m2. For guidance on roof and ceiling mass refer to Appendix A. ii) Where rafters or trusses are supported directly over studs or within 1.5 times the thickness of the top plate from the studs the top plate may be a minimum 35 mm deep. iii) Where plates support concentrated loads such as roof beams, struts, strutting beams, hanging beams, counter beams, combined strutting/hanging beams or girder trusses etc., the load shall be supported directly over a stud(s) designed to carry the load or the plate stiffened in accordance with Clause 6.2.2.3. iv) Plates may be trenched up to a maximum of 3 mm for studs. v) Multiple plates shall be nailed together as per Clause 2.5. vi) For design parameters refer to Figure 6.19. vii) Where wind uplift forces on rafters or trusses are taken to the substructure, bypassing the top plate, the top plate size may be determined using the tie-down spacing of “0” in the table.

NOTES: i) Maximum spans are based on the support of roof mass only for a coupled roof and the combined roof plus ceiling mass for a cathedral roof. For guidance on roof and ceiling mass refer to Appendix A. ii) Allowable overhangs are based on a maximum depth of birdsmouth of D/3. Refer Figure 7.28. iii) Where rafters are not birdsmouthed, the allowable overhang may be increased to 30% of the allowable single span for that member. Overhang shall not exceed 50% of actual backspan. iv) Overhang limits do not apply where rafter ends are tied back to wall frame. v) Overhang limits are only applicable where rafter ends are supported by a structural fascia board. Refer to Clause 7.3.13.2. vi) Multiple members shall be nailed together as per Clause 2.3. vii) For design parameters refer to Figures 7.26 and 7.27.

NOTES: i) Maximum spans are based on the support of roof or roof plus ceiling mass for a cathedral roof. For guidance on roof and ceiling mass refer to Appendix A. ii) Allowable overhangs are based on no birdsmouth or notching. Overhangs shall not exceed 50% of actual backspan. iii) Minimum bearing length = 35 mm at end supports and 70 mm at internal supports for continuous members. Subscript values, where applicable, indicate the minimum additional bearing length where required to be greater than 35 mm at end supports and 75 mm at internal supports. iv) Multiple members nailed together as per Clause 2.3. v) For design parameters refer to Figure 7.29.

NOTES: i) Maximum spans are based on the support of roof mass only for a coupled roof and the combined roof plus ceiling mass for a cathedral roof. For guidance on roof and ceiling mass refer to Appendix A. ii) Allowable overhangs are based on a maximum depth of birdsmouth of D/3. Refer Figure 7.28. iii) Where rafters are not birdsmouthed, the allowable overhang may be increased to 30% of the allowable single span for that member. Overhang shall not exceed 50% of actual backspan. iv) Overhang limits do not apply where rafter ends are tied back to wall frame. v) Overhang limits are only applicable where rafter ends are supported by a structural fascia board. Refer to Clause 7.3.13.2. vi) Multiple members shall be nailed together as per Clause 2.3. vii) For design parameters refer to Figures 7.26 and 7.27.

NOTES: i) Maximum spans are based on the support of roof or roof plus ceiling mass for a cathedral roof. For guidance on roof and ceiling mass refer to Appendix A. ii) Allowable overhangs are based on no birdsmouth or notching. Overhangs shall not exceed 50% of actual backspan. iii) Minimum bearing length = 35 mm at end supports and 70 mm at internal supports for continuous members. Subscript values, where applicable, indicate the minimum additional bearing length where required to be greater than 35 mm at end supports and 75 mm at internal supports. iv) Multiple members nailed together as per Clause 2.3. v) For design parameters refer to Figure 7.29.

NOTES: i) Maximum spans are based on the support of roof mass only for a coupled roof and the combined roof plus ceiling mass for a cathedral roof. For guidance on roof and ceiling mass refer to Appendix A. ii) Allowable overhangs are based on a maximum depth of birdsmouth of D/3. Refer Figure 7.28. iii) Where rafters are not birdsmouthed, the allowable overhang may be increased to 30% of the allowable single span for that member. Overhang shall not exceed 50% of actual backspan. iv) Overhang limits do not apply where rafter ends are tied back to wall frame. v) Overhang limits are only applicable where rafter ends are supported by a structural fascia board. Refer to Clause 7.3.13.2. vi) Multiple members shall be nailed together as per Clause 2.3. vii) For design parameters refer to Figures 7.26 and 7.27.

NOTES: i) Maximum roof load widths are based on the support of a maximum total tile roof, framing and ceiling mass of 90 kg/m2. For guidance on roof and ceiling mass refer to Appendix B. ii) Where rafters or trusses are supported directly over studs or within 1.5 times the thickness of the top plate from the studs the top plate may be a minimum 35 mm deep. iii) Where plates support concentrated loads such as roof beams, struts, strutting beams, hanging beams, counter beams, combined strutting/hanging beams or girder trusses etc., the load shall be supported directly over a stud(s) designed to carry the load or the plate stiffened in accordance with Clause 6.2.2.3. iv) Plates may be trenched up to a maximum of 3 mm for studs. v) Multiple plates shall be nailed together as per Clause 2.5. vi) For design parameters refer to Figure 6.19. vii) Where wind uplift forces on rafters or trusses are taken to the substructure, bypassing the top plate, the top plate size may be determined using the tie-down spacing of “0” in the table.

NOTES: i) Maximum spans are based on the support of a maximum sheet roof mass of 20 kg/m2 plus a total ceiling mass of 12 kg/m2 (including ceiling joists)and a maximum tile roof mass of 60 kg/m2 plus a total ceiling mass of 12 kg/m2 . For guidance on roof and ceiling mass refer to Appendix B. The mass of rafters and underpurlins is accommodated in the span calculations. ii) Where the depth to breadth ratio exceeds 3:1, G.I. strapping or similar restraint is to be provided to the top edge of the beam at beam ends. Refer to Clause 7.2.26. iii) Beam ends may be chamfered to a minimum depth of 100 mm or 1/3 of the beam depth, whichever is greater. iv) Where hanging beam spans are not the same each side of the strutting/counter beam, the average of the spans may be used. v) Minimum bearing length = 70 mm at end supports. vi) Multiple members nailed together as per Clause 2.3. vii) For design parameters refer to Figure 7.23.

NOTES: i) Maximum spans are based on the support of roof mass only up to a maximum sheet roof mass of 20 kg/m2 and tile roof mass of 60 kg/m2 . For guidance on roof and ceiling mass refer to Appendix B. The mass of rafters and underpurlins is accommodated in the span calculations. ii) Where the depth to breadth ratio exceeds 3:1 G.I. strapping or similar restraint to the top edge of the beam is to be provided at the strutting points and at beam ends. Refer to Clause 7.2.26. iii) Beam ends may be chamfered to a minimum depth of 100 mm or 1/3 of the beam depth, which ever is greater. iv) A minimum initial clearance of 25 mm shall be provided at mid-span between the underside of the strutting beam and the tops of ceiling joist, ceiling lining or ceiling battens as appropriate. v) Minimum bearing length = 70 mm at end supports. vi) Multiple members nailed together as per Clause 2.3. vii) For design parameters refer to Figure 7.24.

NOTES TO TABLE 29: i) Maximum spans are based on the support of roof mass only for a coupled roof and the combined roof plus ceiling mass for a cathedral roof. For guidance on roof and ceiling mass refer to Appendix B. ii) Allowable overhangs are based on a maximum depth of birdsmouth of D/3. Refer Figure 7.28. iii) Where rafters are not birdsmouthed, the allowable overhang may be increased to 30% of the allowable single span for that member. Overhang shall not exceed 50% of actual backspan. iv) Overhang limits do not apply where rafter ends are tied back to wall frame. v) Overhang limits are only applicable where rafter ends are supported by a structural fascia board. Refer to Clause 7.3.13.2. vi) Multiple members shall be nailed together as per Clause 2.3. vii) For design parameters refer to Figures 7.26 and 7.27.

NOTES: i) Maximum roof load widths are based on the support of a maximum total tile roof, framing and ceiling mass of 90 kg/m2. For guidance on roof and ceiling mass refer to Appendix B. ii) Where rafters or trusses are supported directly over studs or within 1.5 times the thickness of the top plate from the studs the top plate may be a minimum 35 mm deep. iii) Where plates support concentrated loads such as roof beams, struts, strutting beams, hanging beams, counter beams, combined strutting/hanging beams or girder trusses etc., the load shall be supported directly over a stud(s) designed to carry the load or the plate stiffened in accordance with Clause 6.2.2.3. iv) Plates may be trenched up to a maximum of 3 mm for studs. v) Multiple plates shall be nailed together as per Clause 2.5. vi) For design parameters refer to Figure 6.19. vii) Where wind uplift forces on rafters or trusses are taken to the substructure, bypassing the top plate, the top plate size may be determined using the tie-down spacing of “0” in the table.

NOTES: i) Maximum spans are based on the support of roof mass only for a coupled roof and the combined roof plus ceiling mass for a cathedral roof. For guidance on roof and ceiling mass refer to Appendix B. ii) Allowable overhangs are based on a maximum depth of birdsmouth of D/3. Refer Figure 7.28. iii) Where rafters are not birdsmouthed, the allowable overhang may be increased to 30% of the allowable single span for that member. Overhang shall not exceed 50% of actual backspan. iv) Overhang limits do not apply where rafter ends are tied back to wall frame. v) Overhang limits are only applicable where rafter ends are supported by a structural fascia board. Refer to Clause 7.3.13.2. vi) Multiple members shall be nailed together as per Clause 2.3. vii) For design parameters refer to Figures 7.26 and 7.27.

NOTES: i) Maximum Lintel Spans are based on the support of a maximum total sheet roof, framing and ceiling mass of 40 kg/m2. For guidance on roof and ceiling mass refer to Appendix B. ii) For lintels supporting hanging beams, the area supported shall be taken as one half of the ceiling area supported by the lintel and the size determined from the sheet roof section. iii) Minimum bearing length = 35 mm at end supports. Subscript values indicate the minimum additional bearing length where required to be greater than 35 mm. iv) Multiple members nailed together as per Clause 2.3. v) For roof area supported refer Clause 2.6.5. vi) Lintels must be used in conjunction with top plates, ledgers and head trimmers. vii) When lintels are used to their maximun design limits, deflections of up to 10 mm (deadload) or 15mm (live load) may be expected. viii) The roof area supported by the lintel should only be that proportion of roof area contributing to the concentrated load on the lintel, ie the roof area input for a lintel supporting a strutting beam should be proportioned according to the area distributed to either end of the strutting beam.

NOTES: i) Maximum spans are based on the support of roof mass only for a coupled roof and the combined roof plus ceiling mass for a cathedral roof. For guidance on roof and ceiling mass refer to Appendix B. ii) Allowable overhangs are based on a maximum depth of birdsmouth of D/3. Refer Figure 7.28. iii) Where rafters are not birdsmouthed, the allowable overhang may be increased to 30% of the allowable single span for that member. Overhang shall not exceed 50% of actual backspan. iv) Overhang limits do not apply where rafter ends are tied back to wall frame. v) Overhang limits are only applicable where rafter ends are supported by a structural fascia board. Refer to Clause 7.3.13.2. vi) Multiple members shall be nailed together as per Clause 2.3. vii) For design parameters refer to Figures 7.26 and 7.27.

NOTES: i) Maximum spans are based on the support of roof mass only for a coupled roof and the combined roof plus ceiling mass for a cathedral roof. For guidance on roof and ceiling mass refer to Appendix B. ii) Allowable overhangs are based on a maximum depth of birdsmouth of D/3. Refer Figure 7.28. iii) Where rafters are not birdsmouthed, the allowable overhang may be increased to 30% of the allowable single span for that member. Overhang shall not exceed 50% of actual backspan. iv) Overhang limits do not apply where rafter ends are tied back to wall frame. v) Overhang limits are only applicable where rafter ends are supported by a structural fascia board. Refer to Clause 7.3.13.2. vi) Multiple members shall be nailed together as per Clause 2.3. vii) For design parameters refer to Figures 7.26 and 7.27.

NOTES: i) Maximum roof load widths are based on the support of a maximum total sheet roof, framing and ceiling mass of 40 kg/m2. For guidance on roof and ceiling mass refer to Appendix B. ii) Where rafters or trusses are supported directly over studs or within 1.5 times the thickness of the top plate from the studs the top plate may be a minimum 35 mm deep. iii) Where plates support concentrated loads such as roof beams, struts, strutting beams, hanging beams, counter beams, combined strutting/hanging beams or girder trusses etc., the load shall be supported directly over a stud(s) designed to carry the load or the plate stiffened in accordance with Clause 6.2.2.3. iv) Plates may be trenched up to a maximum of 3 mm for studs. v) Multiple plates shall be nailed together as per Clause 2.5. vi) For design parameters refer to Figure 6.19. vii) Where wind uplift forces on rafters or trusses are taken to the substructure, bypassing the top plate, the top plate size may be determined using the tie-down spacing of “0” in the table.

NOTES: i) Maximum spans are based on the support of roof mass only for a coupled roof and the combined roof plus ceiling mass for a cathedral roof. For guidance on roof and ceiling mass refer to Appendix B. ii) Allowable overhangs are based on a maximum depth of birdsmouth of D/3. Refer Figure 7.28. iii) Where rafters are not birdsmouthed, the allowable overhang may be increased to 30% of the allowable single span for that member. Overhang shall not exceed 50% of actual backspan. iv) Overhang limits do not apply where rafter ends are tied back to wall frame. v) Overhang limits are only applicable where rafter ends are supported by a structural fascia board. Refer to Clause 7.3.13.2. vi) Multiple members shall be nailed together as per Clause 2.3. vii) For design parameters refer to Figures 7.26 and 7.27.

NOTES: i) Maximum floor joist spans supporting roof loads are based on the support of a maximum total sheet roof, framing and ceiling mass of 40 kg/m2 , maximum total tile roof, framing and ceiling mass of 90 kg/m2 and a maximum flooring mass of 40 kg/m2. ii) A Roof Load Width of ”0” shall be used for floor joist not supporting roof loads. iii) The sizes given in this table are not suitable where heavy point loads, except those allowed by Clause 4.3.2.4, are supported within the joist span. iv) For the lower storey of two storey construction, floor joists shall not support roof or upper floor loads within their span. v) Where the ends of joist do not support roof loads, the joist may cantilever 25% of the allowable single span for size used, except that the cantilever shall not exceed 50% of the actual backspan. vi) Joists crippled over supports shall be considered as single span joists. Refer Clause 2.7.5.4. vii) Where joist size D/B > 4 restraint may be required. Refer Clause 4.2.2.3. viii) For design parameters refer to Figure 4.9.

NOTES: i) Maximum roof load widths are based on the support of a maximum total tile roof, framing and ceiling mass of 90 kg/m2. For guidance on roof and ceiling mass refer to Appendix B. ii) Where rafters or trusses are supported directly over studs or within 1.5 times the thickness of the top plate from the studs the top plate may be a minimum 35 mm deep. iii) Where plates support concentrated loads such as roof beams, struts, strutting beams, hanging beams, counter beams, combined strutting/hanging beams or girder trusses etc., the load shall be supported directly over a stud(s) designed to carry the load or the plate stiffened in accordance with Clause 6.2.2.3. iv) Plates may be trenched up to a maximum of 3 mm for studs. v) Multiple plates shall be nailed together as per Clause 2.5. vi) For design parameters refer to Figure 6.19. vii) Where wind uplift forces on rafters or trusses are taken to the substructure, bypassing the top plate, the top plate size may be determined using the tie-down spacing of “0” in the table.

NOTES: i) Maximum Lintel Spans are based on the support of a maximum total sheet roof, framing and ceiling mass of 40 kg/m2. For guidance on roof and ceiling mass refer to Appendix B. ii) For lintels supporting hanging beams, the area supported shall be taken as one half of the ceiling area supported by the lintel and the size determined from the sheet roof section. iii) Minimum bearing length = 35 mm at end supports. Subscript values indicate the minimum additional bearing length where required to be greater than 35 mm. iv) Multiple members nailed together as per Clause 2.3. v) For roof area supported refer Clause 2.6.5. vi) Lintels must be used in conjunction with top plates, ledgers and head trimmers. vii) When lintels are used to their maximun design limits, deflections of up to 10 mm (deadload) or 15mm (live load) may be expected. viii) The roof area supported by the lintel should only be that proportion of roof area contributing to the concentrated load on the lintel, ie the roof area input for a lintel supporting a strutting beam should be proportioned according to the area distributed to either end of the strutting beam.

NOTES: i) Maximum Lintel Spans are based on the support of a maximum total tile roof, framing and ceiling mass of 90 kg/m2. For guidance on roof and ceiling mass refer to Appendix B. ii) For lintels supporting hanging beams, the area supported shall be taken as one half of the ceiling area supported by the lintel and the size determined from the sheet roof section. iii) Minimum bearing length = 35 mm at end supports. Subscript values indicate the minimum additional bearing length where required to be greater than 35 mm. iv) Multiple members nailed together as per Clause 2.3. v) For roof area supported refer Clause 2.6.5. vi) Lintels must be used in conjunction with top plates, ledgers and head trimmers. vii) When lintels are used to their maximun design limits, deflections of up to 10 mm (deadload) or 15mm (live load) may be expected. viii) The roof area supported by the lintel should only be that proportion of roof area contributing to the concentrated load on the lintel, ie the roof area input for a lintel supporting a strutting beam should be proportioned according to the area distributed to either end of the strutting beam.

NOTES: i) Maximum spans are based on the support of roof mass only for a coupled roof and the combined roof plus ceiling mass for a cathedral roof. For guidance on roof and ceiling mass refer to Appendix B. ii) Allowable overhangs are based on a maximum depth of birdsmouth of D/3. Refer Figure 7.28. iii) Where rafters are not birdsmouthed, the allowable overhang may be increased to 30% of the allowable single span for that member. Overhang shall not exceed 50% of actual backspan. iv) Overhang limits do not apply where rafter ends are tied back to wall frame. v) Overhang limits are only applicable where rafter ends are supported by a structural fascia board. Refer to Clause 7.3.13.2. vi) Multiple members shall be nailed together as per Clause 2.3. vii) For design parameters refer to Figures 7.26 and 7.27.

NOTES i) Maximum Roof Load Widths are based on the support of a maximum total sheet roof, framing and ceiling mass of 40 kg/m2 and a maximum total tile roof, framing and ceiling mass of 90 kg/m2. For guidance on roof and ceiling mass refer to Appendix B. ii) Studs for internal non-loadbearing bracing walls and partitions (not carrying roof loads) shall be as per Clause 6.3.5. iii) Edge distances for some sheet bracing materials may require a minimum stud width of 45 mm for joining sheets. iv) Jamb studs for opening in internal load bearing walls shall be as per Table 10. v) Large stud sizes may be made up by vertical nail lamination as per Clause 2.4. vi) For design parameters refer to Figure 6.1.4. vii) Where roof loads are supported only on studs supporting concentrated loads, posts or jamb studs, the internal walls can be classified as non-loadbearing walls. Refer Clause 6.3.5. viii) Where studs are used for tie-down, the maximum tension load that can be imparted to the stud is 8.5kN per stud or laminate where they are nail laminated.

NOTES: i) Maximum roof load widths are based on the support of a maximum total sheet roof, framing and ceiling mass of 40 kg/m2. For guidance on roof and ceiling mass refer to Appendix B. ii) Where rafters or trusses are supported directly over studs or within 1.5 times the thickness of the top plate from the studs the top plate may be a minimum 35 mm deep. iii) Where plates support concentrated loads such as roof beams, struts, strutting beams, hanging beams, counter beams, combined strutting/hanging beams or girder trusses etc., the load shall be supported directly over a stud(s) designed to carry the load or the plate stiffened in accordance with Clause 6.2.2.3. iv) Plates may be trenched up to a maximum of 3 mm for studs. v) Multiple plates shall be nailed together as per Clause 2.5. vi) For design parameters refer to Figure 6.19. vii) Where wind uplift forces on rafters or trusses are taken to the substructure, bypassing the top plate, the top plate size may be determined using the tie-down spacing of “0” in the table.

NOTES: i) Maximum spans are based on the support of roof mass only up to a maximum sheet roof mass of 20 kg/m2 and tile roof mass of 60 kg/m2 . For guidance on roof and ceiling mass refer to Appendix B. The mass of rafters and underpurlins is accommodated in the span calculations. ii) Where the depth to breadth ratio exceeds 3:1 G.I. strapping or similar restraint to the top edge of the beam is to be provided at the strutting points and at beam ends. Refer to Clause 7.2.26. iii) Beam ends may be chamfered to a minimum depth of 100 mm or 1/3 of the beam depth, which ever is greater. iv) A minimum initial clearance of 25 mm shall be provided at mid-span between the underside of the strutting beam and the tops of ceiling joist, ceiling lining or ceiling battens as appropriate. v) Minimum bearing length = 70 mm at end supports. vi) Multiple members nailed together as per Clause 2.3. COPYRIGHT vii) For design parameters refer to Figure 7.24.

NOTES: i) Maximum spans are based on the support of roof mass only for a coupled roof and the combined roof plus ceiling mass for a cathedral roof. For guidance on roof and ceiling mass refer to Appendix B. ii) Allowable overhangs are based on a maximum depth of birdsmouth of D/3. Refer Figure 7.28. iii) Where rafters are not birdsmouthed, the allowable overhang may be increased to 30% of the allowable single span for that member. Overhang shall not exceed 50% of actual backspan. iv) Overhang limits do not apply where rafter ends are tied back to wall frame. v) Overhang limits are only applicable where rafter ends are supported by a structural fascia board. Refer to Clause 7.3.13.2. vi) Multiple members shall be nailed together as per Clause 2.3. vii) For design parameters refer to Figures 7.26 and 7.27.

NOTES: i) Maximum roof load widths are based on the support of a maximum total tile roof, framing and ceiling mass of 90 kg/m2. For guidance on roof and ceiling mass refer to Appendix B. ii) Where rafters or trusses are supported directly over studs or within 1.5 times the thickness of the top plate from the studs the top plate may be a minimum 35 mm deep. iii) Where plates support concentrated loads such as roof beams, struts, strutting beams, hanging beams, counter beams, combined strutting/hanging beams or girder trusses etc., the load shall be supported directly over a stud(s) designed to carry the load or the plate stiffened in accordance with Clause 6.2.2.3. iv) Plates may be trenched up to a maximum of 3 mm for studs. v) Multiple plates shall be nailed together as per Clause 2.5. vi) For design parameters refer to Figure 6.19. vii) Where wind uplift forces on rafters or trusses are taken to the substructure, bypassing the top plate, the top plate size may be determined using the tie-down spacing of “0” in the table.

NOTES: i) Maximum Lintel Spans are based on the support of a maximum total sheet roof, framing and ceiling mass of 40 kg/m2. For guidance on roof and ceiling mass refer to Appendix B. ii) For lintels supporting hanging beams, the area supported shall be taken as one half of the ceiling area supported by the lintel and the size determined from the sheet roof section. iii) Minimum bearing length = 35 mm at end supports. Subscript values indicate the minimum additional bearing length where required to be greater than 35 mm. iv) Multiple members nailed together as per Clause 2.3. v) For roof area supported refer Clause 2.6.5. vi) Lintels must be used in conjunction with top plates, ledgers and head trimmers. vii) When lintels are used to their maximun design limits, deflections of up to 10 mm (deadload) or 15mm (live load) may be expected. viii) The roof area supported by the lintel should only be that proportion of roof area contributing to the concentrated load on the lintel, ie the roof area input for a lintel supporting a strutting beam should be proportioned according to the area distributed to either end of the strutting beam.

NOTES: i) Maximum spans are based on the support of roof mass only for a coupled roof and the combined roof plus ceiling mass for a cathedral roof. For guidance on roof and ceiling mass refer to Appendix B. ii) Allowable overhangs are based on a maximum depth of birdsmouth of D/3. Refer Figure 7.28. iii) Where rafters are not birdsmouthed, the allowable overhang may be increased to 30% of the allowable single span for that member. Overhang shall not exceed 50% of actual backspan. iv) Overhang limits do not apply where rafter ends are tied back to wall frame. v) Overhang limits are only applicable where rafter ends are supported by a structural fascia board. Refer to Clause 7.3.13.2. vi) Multiple members shall be nailed together as per Clause 2.3. vii) For design parameters refer to Figures 7.26 and 7.27.

NOTES: i) Maximum roof load widths are based on the support of a maximum total tile roof, framing and ceiling mass of 90 kg/m2. For guidance on roof and ceiling mass refer to Appendix B. ii) Where rafters or trusses are supported directly over studs or within 1.5 times the thickness of the top plate from the studs the top plate may be a minimum 35 mm deep. iii) Where plates support concentrated loads such as roof beams, struts, strutting beams, hanging beams, counter beams, combined strutting/hanging beams or girder trusses etc., the load shall be supported directly over a stud(s) designed to carry the load or the plate stiffened in accordance with Clause 6.2.2.3. iv) Plates may be trenched up to a maximum of 3 mm for studs. v) Multiple plates shall be nailed together as per Clause 2.5. vi) For design parameters refer to Figure 6.19. vii) Where wind uplift forces on rafters or trusses are taken to the substructure, bypassing the top plate, the top plate size may be determined using the tie-down spacing of “0” in the table.

NOTES: i) Maximum Lintel Spans are based on the support of a maximum total sheet roof, framing and ceiling mass of 40 kg/m2. For guidance on roof and ceiling mass refer to Appendix B. ii) For lintels supporting hanging beams, the area supported shall be taken as one half of the ceiling area supported by the lintel and the size determined from the sheet roof section. iii) Minimum bearing length = 35 mm at end supports. Subscript values indicate the minimum additional bearing length where required to be greater than 35 mm. iv) Multiple members nailed together as per Clause 2.3. v) For roof area supported refer Clause 2.6.5. vi) Lintels must be used in conjunction with top plates, ledgers and head trimmers. vii) When lintels are used to their maximun design limits, deflections of up to 10 mm (deadload) or 15mm (live load) may be expected. viii) The roof area supported by the lintel should only be that proportion of roof area contributing to the concentrated load on the lintel, ie the roof area input for a lintel supporting a strutting beam should be proportioned according to the area distributed to either end of the strutting beam.

NOTES: i) Maximum Lintel Spans are based on the support of a maximum total tile roof, framing and ceiling mass of 90 kg/m2. For guidance on roof and ceiling mass refer to Appendix B. ii) For lintels supporting hanging beams, the area supported shall be taken as one half of the ceiling area supported by the lintel and the size determined from the sheet roof section. iii) Minimum bearing length = 35 mm at end supports. Subscript values indicate the minimum additional bearing length where required to be greater than 35 mm. iv) Multiple members nailed together as per Clause 2.3. v) For roof area supported refer Clause 2.6.5. vi) Lintels must be used in conjunction with top plates, ledgers and head trimmers. vii) When lintels are used to their maximun design limits, deflections of up to 10 mm (deadload) or 15mm (live load) may be expected. viii) The roof area supported by the lintel should only be that proportion of roof area contributing to the concentrated load on the lintel, ie the roof area input for a lintel supporting a strutting beam should be proportioned according to the area distributed to either end of the strutting beam.

NOTES: i) Maximum spans are based on the support of roof mass only for a coupled roof and the combined roof plus ceiling mass for a cathedral roof. For guidance on roof and ceiling mass refer to Appendix B. ii) Allowable overhangs are based on a maximum depth of birdsmouth of D/3. Refer Figure 7.28. iii) Where rafters are not birdsmouthed, the allowable overhang may be increased to 30% of the allowable single span for that member. Overhang shall not exceed 50% of actual backspan. iv) Overhang limits do not apply where rafter ends are tied back to wall frame. v) Overhang limits are only applicable where rafter ends are supported by a structural fascia board. Refer to Clause 7.3.13.2. vi) Multiple members shall be nailed together as per Clause 2.3. vii) For design parameters refer to Figures 7.26 and 7.27.

NOTES: i) Maximum roof load widths are based on the support of a maximum total tile roof, framing and ceiling mass of 90 kg/m2. For guidance on roof and ceiling mass refer to Appendix B. ii) Where rafters or trusses are supported directly over studs or within 1.5 times the thickness of the top plate from the studs the top plate may be a minimum 35 mm deep. iii) Where plates support concentrated loads such as roof beams, struts, strutting beams, hanging beams, counter beams, combined strutting/hanging beams or girder trusses etc., the load shall be supported directly over a stud(s) designed to carry the load or the plate stiffened in accordance with Clause 6.2.2.3. iv) Plates may be trenched up to a maximum of 3 mm for studs. v) Multiple plates shall be nailed together as per Clause 2.5. vi) For design parameters refer to Figure 6.19. vii) Where wind uplift forces on rafters or trusses are taken to the substructure, bypassing the top plate, the top plate size may be determined using the tie-down spacing of “0” in the table.

For guidance on roof and ceiling mass refer to Appendix B. ii) For lintels supporting hanging beams, the area supported shall be taken as one half of the ceiling area supported by the lintel and the size determined from the sheet roof section. iii) Minimum bearing length = 35 mm at end supports. Subscript values indicate the minimum additional bearing length where required to be greater than 35 mm. iv) Multiple members nailed together as per Clause 2.3. v) For roof area supported refer Clause 2.6.5. vi) Lintels must be used in conjunction with top plates, ledgers and head trimmers. vii) When lintels are used to their maximun design limits, deflections of up to 10 mm (deadload) or 15mm (live load) may be expected. viii) The roof area supported by the lintel should only be that proportion of roof area contributing to the concentrated load on the lintel, ie the roof area input for a lintel supporting a strutting beam should be proportioned according to the area distributed to either end of the strutting beam.

NOTES: i) Maximum spans are based on the support of a maximum sheet roof mass of 20 kg/m2 plus a total ceiling mass of 12 kg/m2 (including ceiling joists)and a maximum tile roof mass of 60 kg/m2 plus a total ceiling mass of 12 kg/m2 . For guidance on roof and ceiling mass refer to Appendix B. The mass of rafters and underpurlins is accommodated in the span calculations. ii) Where the depth to breadth ratio exceeds 3:1, G.I. strapping or similar restraint is to be provided to the top edge of the beam at beam ends. Refer to Clause 7.2.26. iii) Beam ends may be chamfered to a minimum depth of 100 mm or 1/3 of the beam depth, whichever is greater. iv) Where hanging beam spans are not the same each side of the strutting/counter beam, the average of the spans may be used. v) Minimum bearing length = 70 mm at end supports. vi) Multiple members nailed together as per Clause 2.3. vii) For design parameters refer to Figure 7.23.

NOTES: i) Maximum spans are based on the support of roof mass only up to a maximum sheet roof mass of 20 kg/m2 and tile roof mass of 60 kg/m2 . For guidance on roof and ceiling mass refer to Appendix B. The mass of rafters and underpurlins is accommodated in the span calculations. ii) Where the depth to breadth ratio exceeds 3:1 G.I. strapping or similar restraint to the top edge of the beam is to be provided at the strutting points and at beam ends. Refer to Clause 7.2.26. iii) Beam ends may be chamfered to a minimum depth of 100 mm or 1/3 of the beam depth, which ever is greater. iv) A minimum initial clearance of 25 mm shall be provided at mid-span between the underside of the strutting beam and the tops of ceiling joist, ceiling lining or ceiling battens as appropriate. v) Minimum bearing length = 70 mm at end supports. vi) Multiple members nailed together as per Clause 2.3. vii) For design parameters refer to Figure 7.24.

NOTES: i) Maximum spans are based on the support of roof mass only for a coupled roof and the combined roof plus ceiling mass for a cathedral roof. For guidance on roof and ceiling mass refer to Appendix B. ii) Allowable overhangs are based on a maximum depth of birdsmouth of D/3. Refer Figure 7.28. iii) Where rafters are not birdsmouthed, the allowable overhang may be increased to 30% of the allowable single span for that member. Overhang shall not exceed 50% of actual backspan. iv) Overhang limits do not apply where rafter ends are tied back to wall frame. v) Overhang limits are only applicable where rafter ends are supported by a structural fascia board. Refer to Clause 7.3.13.2. vi) Multiple members shall be nailed together as per Clause 2.3. vii) For design parameters refer to Figures 7.26 and 7.27.

NOTES: i) Battens are not suitable for the support of construction loads prior to fixing of the roof cladding. ii) The roof batten sizes determined from the above table accommodate local wind pressure effects near edges of roofs for tile roofs. For sheet roofs, to accommodate local pressure, battens within 1200 mm of edges (hips, ridges, fascias and barges) shall have their spacing reduced by 25% from the tabulated value or alternatively, the breadth of the batten shall be increased by 25%. iii) Allowable spans and overhangs are based on a maximum Sheet Roof Mass of 10 kg/m2 and Tile Roof Mass of 60 kg/m2. Overhangs shall not exceed 50% of actual backspan. iv) For guidance on roof and ceiling mass refer to Appendix B. v) For design parameters refer to Figure 7.30.

NOTES: i) Maximum spans are based on the support of roof mass only up to a maximum sheet roof mass of 20 kg/m2 and tile roof mass of 60 kg/m2 . For guidance on roof and ceiling mass refer to Appendix B. The mass of rafters and underpurlins is accommodated in the span calculations. ii) Where the depth to breadth ratio exceeds 3:1 G.I. strapping or similar restraint to the top edge of the beam is to be provided at the strutting points and at beam ends. Refer to Clause 7.2.26. iii) Beam ends may be chamfered to a minimum depth of 100 mm or 1/3 of the beam depth, which ever is greater. iv) A minimum initial clearance of 25 mm shall be provided at mid-span between the underside of the strutting beam and the tops of ceiling joist, ceiling lining or ceiling battens as appropriate. v) Minimum bearing length = 70 mm at end supports. vi) Multiple members nailed together as per Clause 2.3. vii) For design parameters refer to Figure 7.24.

NOTES: i) Maximum spans are based on the support of roof mass only for a coupled roof and the combined roof plus ceiling mass for a cathedral roof. For guidance on roof and ceiling mass refer to Appendix B. ii) Allowable overhangs are based on a maximum depth of birdsmouth of D/3. Refer Figure 7.28. iii) Where rafters are not birdsmouthed, the allowable overhang may be increased to 30% of the allowable single span for that member. Overhang shall not exceed 50% of actual backspan. iv) Overhang limits do not apply where rafter ends are tied back to wall frame. v) Overhang limits are only applicable where rafter ends are supported by a structural fascia board. Refer to Clause 7.3.13.2. vi) Multiple members shall be nailed together as per Clause 2.3. vii) For design parameters refer to Figures 7.26 and 7.27.

NOTES: i) Battens are not suitable for the support of construction loads prior to fixing of the roof cladding. ii) The roof batten sizes determined from the above table accommodate local wind pressure effects near edges of roofs for tile roofs. For sheet roofs, to accommodate local pressure, battens within 1200 mm of edges (hips, ridges, fascias and barges) shall have their spacing reduced by 25% from the tabulated value or alternatively, the breadth of the batten shall be increased by 25%. iii) Allowable spans and overhangs are based on a maximum Sheet Roof Mass of 10 kg/m2 and Tile Roof Mass of 60 kg/m2. Overhangs shall not exceed 50% of actual backspan. iv) For guidance on roof and ceiling mass refer to Appendix B. v) For design parameters refer to Figure 7.30.

NOTES: i) Maximum roof load widths are based on the support of a maximum total tile roof, framing and ceiling mass of 90 kg/m2. For guidance on roof and ceiling mass refer to Appendix B. ii) Where rafters or trusses are supported directly over studs or within 1.5 times the thickness of the top plate from the studs the top plate may be a minimum 35 mm deep. iii) Where plates support concentrated loads such as roof beams, struts, strutting beams, hanging beams, counter beams, combined strutting/hanging beams or girder trusses etc., the load shall be supported directly over a stud(s) designed to carry the load or the plate stiffened in accordance with Clause 6.2.2.3. iv) Plates may be trenched up to a maximum of 3 mm for studs. v) Multiple plates shall be nailed together as per Clause 2.5. vi) For design parameters refer to Figure 6.19. vii) Where wind uplift forces on rafters or trusses are taken to the substructure, bypassing the top plate, the top plate size may be determined using the tie-down spacing of “0” in the table.

NOTES: i) Maximum Lintel Spans are based on the support of a maximum total sheet roof, framing and ceiling mass of 40 kg/m2. For guidance on roof and ceiling mass refer to Appendix B. ii) For lintels supporting hanging beams, the area supported shall be taken as one half of the ceiling area supported by the lintel and the size determined from the sheet roof section. iii) Minimum bearing length = 35 mm at end supports. Subscript values indicate the minimum additional bearing length where required to be greater than 35 mm. iv) Multiple members nailed together as per Clause 2.3. v) For roof area supported refer Clause 2.6.5. vi) Lintels must be used in conjunction with top plates, ledgers and head trimmers. vii) When lintels are used to their maximun design limits, deflections of up to 10 mm (deadload) or 15mm (live load) may be expected. viii) The roof area supported by the lintel should only be that proportion of roof area contributing to the concentrated load on the lintel, ie the roof area input for a lintel supporting a strutting beam should be proportioned according to the area distributed to either end of the strutting beam.

NOTES: i) Maximum spans are based on the support of roof mass only for a coupled roof and the combined roof plus ceiling mass for a cathedral roof. For guidance on roof and ceiling mass refer to Appendix B. ii) Allowable overhangs are based on a maximum depth of birdsmouth of D/3. Refer Figure 7.28. iii) Where rafters are not birdsmouthed, the allowable overhang may be increased to 30% of the allowable single span for that member. Overhang shall not exceed 50% of actual backspan. iv) Overhang limits do not apply where rafter ends are tied back to wall frame. v) Overhang limits are only applicable where rafter ends are supported by a structural fascia board. Refer to Clause 7.3.13.2. vi) Multiple members shall be nailed together as per Clause 2.3. vii) For design parameters refer to Figures 7.26 and 7.27.

NOTES: i) Battens are not suitable for the support of construction loads prior to fixing of the roof cladding. ii) The roof batten sizes determined from the above table accommodate local wind pressure effects near edges of roofs for tile roofs. For sheet roofs, to accommodate local pressure, battens within 1200 mm of edges (hips, ridges, fascias and barges) shall have their spacing reduced by 25% from the tabulated value or alternatively, the breadth of the batten shall be increased by 25%. iii) Allowable spans and overhangs are based on a maximum Sheet Roof Mass of 10 kg/m2 and Tile Roof Mass of 60 kg/m2. Overhangs shall not exceed 50% of actual backspan. iv) For guidance on roof and ceiling mass refer to Appendix B. v) For design parameters refer to Figure 7.30.

NOTES: i) Maximum spans are based on the support of roof mass only for a coupled roof and the combined roof plus ceiling mass for a cathedral roof. For guidance on roof and ceiling mass refer to Appendix A. ii) Allowable overhangs are based on a maximum depth of birdsmouth of D/3. Refer Figure 7.28. iii) Where rafters are not birdsmouthed, the allowable overhang may be increased to 30% of the allowable single span for that member. Overhang shall not exceed 50% of actual backspan. iv) Overhang limits do not apply where rafter ends are tied back to wall frame. v) Overhang limits are only applicable where rafter ends are supported by a structural fascia board. Refer to Clause 7.3.13.2. vi) Multiple members shall be nailed together as per Clause 2.3. vii) For design parameters refer to Figures 7.26 and 7.27. (viii) Minimum bearing length = 35 mm at end supports and 70 mm at internal supports for continuous members. Subscript values, where applicable, indicate the minimum additional bearing length where required to be greater than 35 mm at end supports and 75 mm at internal supports.

NOTES: i) Maximum roof load widths are based on the support of a maximum total sheet roof, framing and ceiling mass of 40 kg/m2. For guidance on roof and ceiling mass refer to Appendix A. ii) Where rafters or trusses are supported directly over studs or within 1.5 times the thickness of the top plate from the studs the top plate may be a minimum 35 mm deep. iii) Where plates support concentrated loads such as roof beams, struts, strutting beams, hanging beams, counter beams, combined strutting/hanging beams or girder trusses etc., the load shall be supported directly over a stud(s) designed to carry the load or the plate stiffened in accordance with Clause 6.2.2.3. iv) Plates may be trenched up to a maximum of 3 mm for studs. v) Multiple plates shall be nailed together as per Clause 2.5. vi) For design parameters refer to Figure 6.19. vii) Where wind uplift forces on rafters or trusses are taken to the substructure, bypassing the top plate, the top plate size may be determined using the tie-down spacing of “0” in the table.

NOTES: i) Maximum spans are based on the support of roof mass only for a coupled roof and the combined roof plus ceiling mass for a cathedral roof. For guidance on roof and ceiling mass refer to Appendix A. ii) Allowable overhangs are based on a maximum depth of birdsmouth of D/3. Refer Figure 7.28. iii) Where rafters are not birdsmouthed, the allowable overhang may be increased to 30% of the allowable single span for that member. Overhang shall not exceed 50% of actual backspan. iv) Overhang limits do not apply where rafter ends are tied back to wall frame. v) Overhang limits are only applicable where rafter ends are supported by a structural fascia board. Refer to Clause 7.3.13.2. vi) Multiple members shall be nailed together as per Clause 2.3. vii) For design parameters refer to Figures 7.26 and 7.27.

NOTES: i) Maximum spans are based on the support of roof or roof plus ceiling mass for a cathedral roof. For guidance on roof and ceiling mass refer to Appendix A. ii) Allowable overhangs are based on no birdsmouth or notching. Overhangs shall not exceed 50% of actual backspan. iii) Minimum bearing length = 35 mm at end supports and 70 mm at internal supports for continuous members. Subscript values, where applicable, indicate the minimum additional bearing length where required to be greater than 35 mm at end supports and 75 mm at internal supports. iv) Multiple members nailed together as per Clause 2.3. v) For design parameters refer to Figure 7.29.

Australian Standards® Committees of experts from industry, governments, consumers and other relevant sectors prepare Australian Standards. The requirements or recommendations contained in published Standards are a consensus of the views of representative interests and also take account of comments received from other sources. They reflect the latest scientific and industry experience. Australian Standards are kept under continuous review after publication and are updated regularly to take account of changing technology.
International Involvement Standards Australia is responsible for ensuring the Australian viewpoint is considered in the formulation of International Standards and that the latest international experience is incorporated in national Standards. This role is vital in assisting local industry to compete in international markets. Standards Australia represents Australia at both the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC).

Keeping Standards up-to-date Australian Standards® are living documents that reflect progress in science, technology and systems. To maintain their currency, all Standards are periodically reviewed, and new editions are published. Between editions, amendments may be issued. Standards may also be withdrawn. It is important that readers assure themselves they are using a current Standard, which should include any amendments that may have been published since the Standard was published. Detailed information about Australian Standards, drafts, amendments and new projects can be found by visiting www.standards.org.au Standards Australia welcomes suggestions for improvements, and encourages readers to notify us immediately of any apparent inaccuracies or ambiguities.

3/45x90 NOTES: i) Maximum roof load widths are based on the support of a maximum total sheet roof, framing and ceiling mass of 40 kg/m2. For guidance on roof and ceiling mass refer to Appendix A. ii) Where rafters or trusses are supported directly over studs or within 1.5 times the thickness of the top plate from the studs the top plate may be a minimum 35 mm deep. iii) Where plates support concentrated loads such as roof beams, struts, strutting beams, hanging beams, counter beams, combined strutting/hanging beams or girder trusses etc., the load shall be supported directly over a stud(s) designed to carry the load or the plate stiffened in accordance with Clause 6.2.2.3. iv) Plates may be trenched up to a maximum of 3 mm for studs. v) Multiple plates shall be nailed together as per Clause 2.5. vi) For design parameters refer to Figure 6.19. vii) Where wind uplift forces on rafters or trusses are taken to the substructure, bypassing the top plate, the top plate size may be determined using the tie-down spacing of “0” in the table.

NOTES: i) Maximum spans are based on the support of roof mass only for a coupled roof and the combined roof plus ceiling mass for a cathedral roof. For guidance on roof and ceiling mass refer to Appendix A. ii) Allowable overhangs are based on a maximum depth of birdsmouth of D/3. Refer Figure 7.28. iii) Where rafters are not birdsmouthed, the allowable overhang may be increased to 30% of the allowable single span for that member. Overhang shall not exceed 50% of actual backspan. iv) Overhang limits do not apply where rafter ends are tied back to wall frame. v) Overhang limits are only applicable where rafter ends are supported by a structural fascia board. Refer to Clause 7.3.13.2. vi) Multiple members shall be nailed together as per Clause 2.3. vii) For design parameters refer to Figures 7.26 and 7.27.

NOTES: i) Maximum spans are based on the support of roof or roof plus ceiling mass for a cathedral roof. For guidance on roof and ceiling mass refer to Appendix A. ii) Allowable overhangs are based on no birdsmouth or notching. Overhangs shall not exceed 50% of actual backspan. iii) Minimum bearing length = 35 mm at end supports and 70 mm at internal supports for continuous members. Subscript values, where applicable, indicate the minimum additional bearing length where required to be greater than 35 mm at end supports and 75 mm at internal supports. iv) Multiple members nailed together as per Clause 2.3. v) For design parameters refer to Figure 7.29.

NOTES: i) Maximum roof load widths are based on the support of a maximum total tile roof, framing and ceiling mass of 90 kg/m2. For guidance on roof and ceiling mass refer to Appendix B. ii) Where rafters or trusses are supported directly over studs or within 1.5 times the thickness of the top plate from the studs the top plate may be a minimum 35 mm deep. iii) Where plates support concentrated loads such as roof beams, struts, strutting beams, hanging beams, counter beams, combined strutting/hanging beams or girder trusses etc., the load shall be supported directly over a stud(s) designed to carry the load or the plate stiffened in accordance with Clause 6.2.2.3. iv) Plates may be trenched up to a maximum of 3 mm for studs. v) Multiple plates shall be nailed together as per Clause 2.5. vi) For design parameters refer to Figure 6.19. vii) Where wind uplift forces on rafters or trusses are taken to the substructure, bypassing the top plate, the top plate size may be determined using the tie-down spacing of “0” in the table.

NOTES: i) Maximum Lintel Spans are based on the support of a maximum total sheet roof, framing and ceiling mass of 40 kg/m2. For guidance on roof and ceiling mass refer to Appendix B. ii) For lintels supporting hanging beams, the area supported shall be taken as one half of the ceiling area supported by the lintel and the size determined from the sheet roof section. iii) Minimum bearing length = 35 mm at end supports. Subscript values indicate the minimum additional bearing length where required to be greater than 35 mm. iv) Multiple members nailed together as per Clause 2.3. v) For roof area supported refer Clause 2.6.5. vi) Lintels must be used in conjunction with top plates, ledgers and head trimmers. vii) When lintels are used to their maximun design limits, deflections of up to 10 mm (deadload) or 15mm (live load) may be expected. viii) The roof area supported by the lintel should only be that proportion of roof area contributing to the concentrated load on the lintel, ie the roof area input for a lintel supporting a strutting beam should be proportioned according to the area distributed to either end of the strutting beam.

NOTES: i) Maximum Lintel Spans are based on the support of a maximum total tile roof, framing and ceiling mass of 90 kg/m2. For guidance on roof and ceiling mass refer to Appendix B. ii) For lintels supporting hanging beams, the area supported shall be taken as one half of the ceiling area supported by the lintel and the size determined from the sheet roof section. iii) Minimum bearing length = 35 mm at end supports. Subscript values indicate the minimum additional bearing length where required to be greater than 35 mm. iv) Multiple members nailed together as per Clause 2.3. v) For roof area supported refer Clause 2.6.5. vi) Lintels must be used in conjunction with top plates, ledgers and head trimmers. vii) When lintels are used to their maximun design limits, deflections of up to 10 mm (deadload) or 15mm (live load) may be expected. viii) The roof area supported by the lintel should only be that proportion of roof area contributing to the concentrated load on the lintel, ie the roof area input for a lintel supporting a strutting beam should be proportioned according to the area distributed to either end of the strutting beam.

NOTES: i) Maximum spans are based on the support of roof mass only up to a maximum sheet roof mass of 20 kg/m2 and tile roof mass of 60 kg/m2 . For guidance on roof and ceiling mass refer to Appendix B. The mass of rafters and underpurlins is accommodated in the span calculations. ii) Where the depth to breadth ratio exceeds 3:1 G.I. strapping or similar restraint to the top edge of the beam is to be provided at the strutting points and at beam ends. Refer to Clause 7.2.26. iii) Beam ends may be chamfered to a minimum depth of 100 mm or 1/3 of the beam depth, which ever is greater. iv) A minimum initial clearance of 25 mm shall be provided at mid-span between the underside of the strutting beam and the tops of ceiling joist, ceiling lining or ceiling battens as appropriate. v) Minimum bearing length = 70 mm at end supports. vi) Multiple members nailed together as per Clause 2.3. vii) For design parameters refer to Figure 7.24.

NOTES: i) Maximum spans are based on the support of roof mass only for a coupled roof and the combined roof plus ceiling mass for a cathedral roof. For guidance on roof and ceiling mass refer to Appendix B. ii) Allowable overhangs are based on a maximum depth of birdsmouth of D/3. Refer Figure 7.28. iii) Where rafters are not birdsmouthed, the allowable overhang may be increased to 30% of the allowable single span for that member. Overhang shall not exceed 50% of actual backspan. iv) Overhang limits do not apply where rafter ends are tied back to wall frame. v) Overhang limits are only applicable where rafter ends are supported by a structural fascia board. Refer to Clause 7.3.13.2. vi) Multiple members shall be nailed together as per Clause 2.3. vii) For design parameters refer to Figures 7.26 and 7.27.

NOTES: i) Battens are not suitable for the support of construction loads prior to fixing of the roof cladding. ii) The roof batten sizes determined from the above table accommodate local wind pressure effects near edges of roofs for tile roofs. For sheet roofs, to accommodate local pressure, battens within 1200 mm of edges (hips, ridges, fascias and barges) shall have their spacing reduced by 25% from the tabulated value or alternatively, the breadth of the batten shall be increased by 25%. iii) Allowable spans and overhangs are based on a maximum Sheet Roof Mass of 10 kg/m2 and Tile Roof Mass of 60 kg/m2. Overhangs shall not exceed 50% of actual backspan. iv) For guidance on roof and ceiling mass refer to Appendix B. v) For design parameters refer to Figure 7.30.

NOTES: i) Maximum spans are based on the support of roof mass only for a coupled roof and the combined roof plus ceiling mass for a cathedral roof. For guidance on roof and ceiling mass refer to Appendix B. ii) Allowable overhangs are based on a maximum depth of birdsmouth of D/3. Refer Figure 7.28. iii) Where rafters are not birdsmouthed, the allowable overhang may be increased to 30% of the allowable single span for that member. Overhang shall not exceed 50% of actual backspan. iv) Overhang limits do not apply where rafter ends are tied back to wall frame. v) Overhang limits are only applicable where rafter ends are supported by a structural fascia board. Refer to Clause 7.3.13.2. vi) Multiple members shall be nailed together as per Clause 2.3. vii) For design parameters refer to Figures 7.26 and 7.27.

NOTES: i) Battens are not suitable for the support of construction loads prior to fixing of the roof cladding. ii) The roof batten sizes determined from the above table accommodate local wind pressure effects near edges of roofs for tile roofs. For sheet roofs, to accommodate local pressure, battens within 1200 mm of edges (hips, ridges, fascias and barges) shall have their spacing reduced by 25% from the tabulated value or alternatively, the breadth of the batten shall be increased by 25%. iii) Allowable spans and overhangs are based on a maximum Sheet Roof Mass of 10 kg/m2 and Tile Roof Mass of 60 kg/m2. Overhangs shall not exceed 50% of actual backspan. iv) For guidance on roof and ceiling mass refer to Appendix B. v) For design parameters refer to Figure 7.30.

NOTES: i) Maximum roof load widths are based on the support of a maximum total sheet roof, framing and ceiling mass of 40 kg/m2. For guidance on roof and ceiling mass refer to Appendix B. ii) Where rafters or trusses are supported directly over studs or within 1.5 times the thickness of the top plate from the studs the top plate may be a minimum 35 mm deep. iii) Where plates support concentrated loads such as roof beams, struts, strutting beams, hanging beams, counter beams, combined strutting/hanging beams or girder trusses etc., the load shall be supported directly over a stud(s) designed to carry the load or the plate stiffened in accordance with Clause 6.2.2.3. iv) Plates may be trenched up to a maximum of 3 mm for studs. v) Multiple plates shall be nailed together as per Clause 2.5. vi) For design parameters refer to Figure 6.19. vii) Where wind uplift forces on rafters or trusses are taken to the substructure, bypassing the top plate, the top plate size may be determined using the tie-down spacing of “0” in the table.

NOTES: i) Maximum spans are based on the support of roof mass only up to a maximum sheet roof mass of 20 kg/m2 and tile roof mass of 60 kg/m2 . For guidance on roof and ceiling mass refer to Appendix B. The mass of rafters and underpurlins is accommodated in the span calculations. ii) Where the depth to breadth ratio exceeds 3:1 G.I. strapping or similar restraint to the top edge of the beam is to be provided at the strutting points and at beam ends. Refer to Clause 7.2.26. iii) Beam ends may be chamfered to a minimum depth of 100 mm or 1/3 of the beam depth, which ever is greater. iv) A minimum initial clearance of 25 mm shall be provided at mid-span between the underside of the strutting beam and the tops of ceiling joist, ceiling lining or ceiling battens as appropriate. v) Minimum bearing length = 70 mm at end supports. vi) Multiple members nailed together as per Clause 2.3. vii) For design parameters refer to Figure 7.24.

NOTES: i) Maximum spans are based on the support of roof mass only for a coupled roof and the combined roof plus ceiling mass for a cathedral roof. For guidance on roof and ceiling mass refer to Appendix B. ii) Allowable overhangs are based on a maximum depth of birdsmouth of D/3. Refer Figure 7.28. iii) Where rafters are not birdsmouthed, the allowable overhang may be increased to 30% of the allowable single span for that member. Overhang shall not exceed 50% of actual backspan. iv) Overhang limits do not apply where rafter ends are tied back to wall frame. v) Overhang limits are only applicable where rafter ends are supported by a structural fascia board. Refer to Clause 7.3.13.2. vi) Multiple members shall be nailed together as per Clause 2.3. vii) For design parameters refer to Figures 7.26 and 7.27.

NOTES: i) Battens are not suitable for the support of construction loads prior to fixing of the roof cladding. ii) The roof batten sizes determined from the above table accommodate local wind pressure effects near edges of roofs for tile roofs. For sheet roofs, to accommodate local pressure, battens within 1200 mm of edges (hips, ridges, fascias and barges) shall have their spacing reduced by 25% from the tabulated value or alternatively, the breadth of the batten shall be increased by 25%. iii) Allowable spans and overhangs are based on a maximum Sheet Roof Mass of 10 kg/m2 and Tile Roof Mass of 60 kg/m2. Overhangs shall not exceed 50% of actual backspan. iv) For guidance on roof and ceiling mass refer to Appendix B. v) For design parameters refer to Figure 7.30.

NOTES: i) Maximum spans are based on the support of roof mass only for a coupled roof and the combined roof plus ceiling mass for a cathedral roof. For guidance on roof and ceiling mass refer to Appendix B. ii) Allowable overhangs are based on a maximum depth of birdsmouth of D/3. Refer Figure 7.28. iii) Where rafters are not birdsmouthed, the allowable overhang may be increased to 30% of the allowable single span for that member. Overhang shall not exceed 50% of actual backspan. iv) Overhang limits do not apply where rafter ends are tied back to wall frame. v) Overhang limits are only applicable where rafter ends are supported by a structural fascia board. Refer to Clause 7.3.13.2. vi) Multiple members shall be nailed together as per Clause 2.3. vii) For design parameters refer to Figures 7.26 and 7.27.

NOTES: i) Battens are not suitable for the support of construction loads prior to fixing of the roof cladding. ii) The roof batten sizes determined from the above table accommodate local wind pressure effects near edges of roofs for tile roofs. For sheet roofs, to accommodate local pressure, battens within 1200 mm of edges (hips, ridges, fascias and barges) shall have their spacing reduced by 25% from the tabulated value or alternatively, the breadth of the batten shall be increased by 25%. iii) Allowable spans and overhangs are based on a maximum Sheet Roof Mass of 10 kg/m2 and Tile Roof Mass of 60 kg/m2. Overhangs shall not exceed 50% of actual backspan. iv) For guidance on roof and ceiling mass refer to Appendix B. v) For design parameters refer to Figure 7.30.

NOTES: i) Maximum roof load widths are based on the support of a maximum total tile roof, framing and ceiling mass of 90 kg/m2. For guidance on roof and ceiling mass refer to Appendix B. ii) Where rafters or trusses are supported directly over studs or within 1.5 times the thickness of the top plate from the studs the top plate may be a minimum 35 mm deep. iii) Where plates support concentrated loads such as roof beams, struts, strutting beams, hanging beams, counter beams, combined strutting/hanging beams or girder trusses etc., the load shall be supported directly over a stud(s) designed to carry the load or the plate stiffened in accordance with Clause 6.2.2.3. iv) Plates may be trenched up to a maximum of 3 mm for studs. v) Multiple plates shall be nailed together as per Clause 2.5. vi) For design parameters refer to Figure 6.19. vii) Where wind uplift forces on rafters or trusses are taken to the substructure, bypassing the top plate, the top plate size may be determined using the tie-down spacing of “0” in the table.

NOTES: i) Maximum Lintel Spans are based on the support of a maximum total tile roof, framing and ceiling mass of 90 kg/m2. For guidance on roof and ceiling mass refer to Appendix B. ii) For lintels supporting hanging beams, the area supported shall be taken as one half of the ceiling area supported by the lintel and the size determined from the sheet roof section. iii) Minimum bearing length = 35 mm at end supports. Subscript values indicate the minimum additional bearing length where required to be greater than 35 mm. iv) Multiple members nailed together as per Clause 2.3. v) For roof area supported refer Clause 2.6.5. vi) Lintels must be used in conjunction with top plates, ledgers and head trimmers. vii) When lintels are used to their maximun design limits, deflections of up to 10 mm (deadload) or 15mm (live load) may be expected. viii) The roof area supported by the lintel should only be that proportion of roof area contributing to the concentrated load on the lintel, ie the roof area input for a lintel supporting a strutting beam should be proportioned according to the area distributed to either end of the strutting beam.

NOTES: i) Maximum spans are based on the support of a maximum sheet roof mass of 20 kg/m2 plus a total ceiling mass of 12 kg/m2 (including ceiling joists)and a maximum tile roof mass of 60 kg/m2 plus a total ceiling mass of 12 kg/m2 . For guidance on roof and ceiling mass refer to Appendix B. The mass of rafters and underpurlins is accommodated in the span calculations. ii) Where the depth to breadth ratio exceeds 3:1, G.I. strapping or similar restraint is to be provided to the top edge of the beam at beam ends. Refer to Clause 7.2.26. iii) Beam ends may be chamfered to a minimum depth of 100 mm or 1/3 of the beam depth, whichever is greater. iv) Where hanging beam spans are not the same each side of the strutting/counter beam, the average of the spans may be used. v) Minimum bearing length = 70 mm at end supports. vi) Multiple members nailed together as per Clause 2.3. vii) For design parameters refer to Figure 7.23.

NOTES: i) Maximum spans are based on the support of roof mass only for a coupled roof and the combined roof plus ceiling mass for a cathedral roof. For guidance on roof and ceiling mass refer to Appendix B. ii) Allowable overhangs are based on a maximum depth of birdsmouth of D/3. Refer Figure 7.28. iii) Where rafters are not birdsmouthed, the allowable overhang may be increased to 30% of the allowable single span for that member. Overhang shall not exceed 50% of actual backspan. iv) Overhang limits do not apply where rafter ends are tied back to wall frame. v) Overhang limits are only applicable where rafter ends are supported by a structural fascia board. Refer to Clause 7.3.13.2. vi) Multiple members shall be nailed together as per Clause 2.3. vii) For design parameters refer to Figures 7.26 and 7.27.

NOTES: i) Battens are not suitable for the support of construction loads prior to fixing of the roof cladding. ii) The roof batten sizes determined from the above table accommodate local wind pressure effects near edges of roofs for tile roofs. For sheet roofs, to accommodate local pressure, battens within 1200 mm of edges (hips, ridges, fascias and barges) shall have their spacing reduced by 25% from the tabulated value or alternatively, the breadth of the batten shall be increased by 25%. iii) Allowable spans and overhangs are based on a maximum Sheet Roof Mass of 10 kg/m2 and Tile Roof Mass of 60 kg/m2. Overhangs shall not exceed 50% of actual backspan. iv) For guidance on roof and ceiling mass refer to Appendix B. v) For design parameters refer to Figure 7.30.

NOTES: i) Maximum roof load widths are based on the support of a maximum total tile roof, framing and ceiling mass of 90 kg/m2. For guidance on roof and ceiling mass refer to Appendix B. ii) Where rafters or trusses are supported directly over studs or within 1.5 times the thickness of the top plate from the studs the top plate may be a minimum 35 mm deep. iii) Where plates support concentrated loads such as roof beams, struts, strutting beams, hanging beams, counter beams, combined strutting/hanging beams or girder trusses etc., the load shall be supported directly over a stud(s) designed to carry the load or the plate stiffened in accordance with Clause 6.2.2.3. iv) Plates may be trenched up to a maximum of 3 mm for studs. v) Multiple plates shall be nailed together as per Clause 2.5. vi) For design parameters refer to Figure 6.19. vii) Where wind uplift forces on rafters or trusses are taken to the substructure, bypassing the top plate, the top plate size may be determined using the tie-down spacing of “0” in the table.

Subscript values indicate the minimum additional bearing length where required to be greater than 35 mm. iv) Multiple members nailed together as per Clause 2.3. v) For roof area supported refer Clause 2.6.5. vi) Lintels must be used in conjunction with top plates, ledgers and head trimmers. vii) When lintels are used to their maximun design limits, deflections of up to 10 mm (deadload) or 15mm (live load) may be expected. viii) The roof area supported by the lintel should only be that proportion of roof area contributing to the concentrated load on the lintel, ie the roof area input for a lintel supporting a strutting beam should be proportioned according to the area distributed to either end of the strutting beam.

NOTES: i) Maximum spans are based on the support of roof mass only for a coupled roof and the combined roof plus ceiling mass for a cathedral roof. For guidance on roof and ceiling mass refer to Appendix B. ii) Allowable overhangs are based on a maximum depth of birdsmouth of D/3. Refer Figure 7.28. iii) Where rafters are not birdsmouthed, the allowable overhang may be increased to 30% of the allowable single span for that member. Overhang shall not exceed 50% of actual backspan. iv) Overhang limits do not apply where rafter ends are tied back to wall frame. v) Overhang limits are only applicable where rafter ends are supported by a structural fascia board. Refer to Clause 7.3.13.2. vi) Multiple members shall be nailed together as per Clause 2.3. vii) For design parameters refer to Figures 7.26 and 7.27.

NOTES: i) Battens are not suitable for the support of construction loads prior to fixing of the roof cladding. ii) The roof batten sizes determined from the above table accommodate local wind pressure effects near edges of roofs for tile roofs. For sheet roofs, to accommodate local pressure, battens within 1200 mm of edges (hips, ridges, fascias and barges) shall have their spacing reduced by 25% from the tabulated value or alternatively, the breadth of the batten shall be increased by 25%. iii) Allowable spans and overhangs are based on a maximum Sheet Roof Mass of 10 kg/m2 and Tile Roof Mass of 60 kg/m2 . Overhangs shall not exceed 50% of actual backspan. iv) For guidance on roof and ceiling mass refer to Appendix B. v) For design parameters refer to Figure 7.30.

NOTES i) Maximum Roof Load Widths are based on the support of a maximum total sheet roof, framing and ceiling mass of 40 kg/m2 and a maximum total tile roof, framing and ceiling mass of 90 kg/m2. For guidance on roof and ceiling mass refer to Appendix B. ii) Studs for internal non-loadbearing bracing walls and partitions (not carrying roof loads) shall be as per Clause 6.3.5. iii) Edge distances for some sheet bracing materials may require a minimum stud width of 45 mm for joining sheets. iv) Jamb studs for opening in internal load bearing walls shall be as per Table 10. v) Large stud sizes may be made up by vertical nail lamination as per Clause 2.4. vi) For design parameters refer to Figure 6.1.4. vii) Where roof loads are supported only on studs supporting concentrated loads, posts or jamb studs, the internal walls can be classified as non-loadbearing walls. Refer Clause 6.3.5. viii) Where studs are used for tie-down, the maximum tension load that can be imparted to the stud is 8.5kN per stud or laminate where they are nail laminated.

NOTES: i) Maximum spans are based on the support of roof mass only for a coupled roof and the combined roof plus ceiling mass for a cathedral roof. For guidance on roof and ceiling mass refer to Appendix B. ii) Allowable overhangs are based on a maximum depth of birdsmouth of D/3. Refer Figure 7.28. iii) Where rafters are not birdsmouthed, the allowable overhang may be increased to 30% of the allowable single span for that member. Overhang shall not exceed 50% of actual backspan. iv) Overhang limits do not apply where rafter ends are tied back to wall frame. v) Overhang limits are only applicable where rafter ends are supported by a structural fascia board. Refer to Clause 7.3.13.2. vi) Multiple members shall be nailed together as per Clause 2.3. vii) For design parameters refer to Figures 7.26 and 7.27.

NOTES: i) Battens are not suitable for the support of construction loads prior to fixing of the roof cladding. ii) The roof batten sizes determined from the above table accommodate local wind pressure effects near edges of roofs for tile roofs. For sheet roofs, to accommodate local pressure, battens within 1200 mm of edges (hips, ridges, fascias and barges) shall have their spacing reduced by 25% from the tabulated value or alternatively, the breadth of the batten shall be increased by 25%. iii) Allowable spans and overhangs are based on a maximum Sheet Roof Mass of 10 kg/m2 and Tile Roof Mass of 60 kg/m2. Overhangs shall not exceed 50% of actual backspan. iv) For guidance on roof and ceiling mass refer to Appendix B. v) For design parameters refer to Figure 7.30.

NOTES: i) Maximum Lintel Spans are based on the support of a maximum total sheet roof, framing and ceiling mass of 40 kg/m2. For guidance on roof and ceiling mass refer to Appendix B. ii) For lintels supporting hanging beams, the area supported shall be taken as one half of the ceiling area supported by the lintel and the size determined from the sheet roof section. iii) Minimum bearing length = 35 mm at end supports. Subscript values indicate the minimum additional bearing length where required to be greater than 35 mm. iv) Multiple members nailed together as per Clause 2.3. v) For roof area supported refer Clause 2.6.5. vi) Lintels must be used in conjunction with top plates, ledgers and head trimmers. vii) When lintels are used to their maximun design limits, deflections of up to 10 mm (deadload) or 15mm (live load) may be expected. viii) The roof area supported by the lintel should only be that proportion of roof area contributing to the concentrated load on the lintel, ie the roof area input for a lintel supporting a strutting beam should be proportioned according to the area distributed to either end of the strutting beam.

NOTES: i) Maximum Lintel Spans are based on the support of a maximum total tile roof, framing and ceiling mass of 90 kg/m2. For guidance on roof and ceiling mass refer to Appendix B. ii) For lintels supporting hanging beams, the area supported shall be taken as one half of the ceiling area supported by the lintel and the size determined from the sheet roof section. iii) Minimum bearing length = 35 mm at end supports. Subscript values indicate the minimum additional bearing length where required to be greater than 35 mm. iv) Multiple members nailed together as per Clause 2.3. v) For roof area supported refer Clause 2.6.5. vi) Lintels must be used in conjunction with top plates, ledgers and head trimmers. vii) When lintels are used to their maximun design limits, deflections of up to 10 mm (deadload) or 15mm (live load) may be expected. viii) The roof area supported by the lintel should only be that proportion of roof area contributing to the concentrated load on the lintel, ie the roof area input for a lintel supporting a strutting beam should be proportioned according to the area distributed to either end of the strutting beam.

NOTES: i) Maximum spans are based on the support of a maximum sheet roof mass of 20 kg/m2 plus a total ceiling mass of 12 kg/m2 (including ceiling joists)and a maximum tile roof mass of 60 kg/m2 plus a total ceiling mass of 12 kg/m2 . For guidance on roof and ceiling mass refer to Appendix B. The mass of rafters and underpurlins is accommodated in the span calculations. ii) Where the depth to breadth ratio exceeds 3:1, G.I. strapping or similar restraint is to be provided to the top edge of the beam at beam ends. Refer to Clause 7.2.26. iii) Beam ends may be chamfered to a minimum depth of 100 mm or 1/3 of the beam depth, whichever is greater. iv) Where hanging beam spans are not the same each side of the strutting/counter beam, the average of the spans may be used. v) Minimum bearing length = 70 mm at end supports. vi) Multiple members nailed together as per Clause 2.3. vii) For design parameters refer to Figure 7.23.

NOTES: i) Maximum spans are based on the support of roof mass only for a coupled roof and the combined roof plus ceiling mass for a cathedral roof. For guidance on roof and ceiling mass refer to Appendix B. ii) Allowable overhangs are based on a maximum depth of birdsmouth of D/3. Refer Figure 7.28. iii) Where rafters are not birdsmouthed, the allowable overhang may be increased to 30% of the allowable single span for that member. Overhang shall not exceed 50% of actual backspan. iv) Overhang limits do not apply where rafter ends are tied back to wall frame. v) Overhang limits are only applicable where rafter ends are supported by a structural fascia board. Refer to Clause 7.3.13.2. vi) Multiple members shall be nailed together as per Clause 2.3. vii) For design parameters refer to Figures 7.26 and 7.27.

NOTES: i) Battens are not suitable for the support of construction loads prior to fixing of the roof cladding. ii) The roof batten sizes determined from the above table accommodate local wind pressure effects near edges of roofs for tile roofs. For sheet roofs, to accommodate local pressure, battens within 1200 mm of edges (hips, ridges, fascias and barges) shall have their spacing reduced by 25% from the tabulated value or alternatively, the breadth of the batten shall be increased by 25%. iii) Allowable spans and overhangs are based on a maximum Sheet Roof Mass of 10 kg/m2 and Tile Roof Mass of 60 kg/m2. Overhangs shall not exceed 50% of actual backspan. iv) For guidance on roof and ceiling mass refer to Appendix B. v) For design parameters refer to Figure 7.30.

NOTES: i) Maximum spans are based on the support of roof mass only for a coupled roof and the combined roof plus ceiling mass for a cathedral roof. For guidance on roof and ceiling mass refer to Appendix B. ii) Allowable overhangs are based on a maximum depth of birdsmouth of D/3. Refer Figure 7.28. iii) Where rafters are not birdsmouthed, the allowable overhang may be increased to 30% of the allowable single span for that member. Overhang shall not exceed 50% of actual backspan. iv) Overhang limits do not apply where rafter ends are tied back to wall frame. v) Overhang limits are only applicable where rafter ends are supported by a structural fascia board. Refer to Clause 7.3.13.2. vi) Multiple members shall be nailed together as per Clause 2.3. vii) For design parameters refer to Figures 7.26 and 7.27.

NOTES: i) Battens are not suitable for the support of construction loads prior to fixing of the roof cladding. ii) The roof batten sizes determined from the above table accommodate local wind pressure effects near edges of roofs for tile roofs. For sheet roofs, to accommodate local pressure, battens within 1200 mm of edges (hips, ridges, fascias and barges) shall have their spacing reduced by 25% from the tabulated value or alternatively, the breadth of the batten shall be increased by 25%. iii) Allowable spans and overhangs are based on a maximum Sheet Roof Mass of 10 kg/m2 and Tile Roof Mass of 60 kg/m2. Overhangs shall not exceed 50% of actual backspan. iv) For guidance on roof and ceiling mass refer to Appendix B. v) For design parameters refer to Figure 7.30.
