PREFACE proudly presents this new publication on LYSAGHT We have simplified the work of engineers with this single book which replaces eight previous publications. Further, it tabluates the propping, composite slab data and fire design for varioius situations, all at one view. Additionally, the book includes BONDEK 2003, our easy-to-use interactive computer software, which enables you to bypass the tables altogether and get quick and more economical solutions with more options. BLUESCOPE LYSAGHT BONDEK®.
is the centre of a formwork and reinforcement system for concrete slab construction. It is a profiled steel sheeting widely accepted by the building construction industry to be highly economical, versatile and robust. It has been used to great effect on many major building projects, as well as countless small ones. BONDEK
This new work now embodies limit state design philosophy, and is based on our extensive research conducted on bondek, so the information is not applicable to other sheeting profiles. We now consider concrete-frame buildings, and several major new technical developments: •
linear elastic analysis of continuous composite slabs;
•
saving of up to 30% in negative reinforcement due to moment redistribution;
•
partial shear connection strength theory for designing positive-moment regions;
•
increased unsupported spans of BONDEK sheeting at the formwork stage (due to the inclusion of negative moment region capacities);
•
design for reliable control of flexural cracking in support regions;
•
New reinforcement grades D500N and D500L; and
•
Enhanced fire design
These developments allow you to make significant improvements compared with the design methods we previously published for slabs using BONDEK.
1.2
SCOPE This manual and computer software provide engineers with a convenient aid to design BONDEK composite slabs used in masonry wall, concrete and steel-frame construction. The book also contains practical construction methods.
1.3
DESIGN METHODS FOR BONDEK There are three ways you can design concrete slabs using
BONDEK.
1. The easiest way of designing for bondek is to run our BONDEK 2003 software included with this manual on the inside back cover (see Chapter 9). 2. Use the design tables in this book. 3. Calculate from first principles using the data in Chapters 2, 3 and 4. Section 1.13 gives a flowchart outlining the process assumed for design.

CORROSION PROTECTION Zinc-coated BONDEK will provide long and trouble free life without additional corrosion protection for Exposure classifications A1, A2 and B1 as defined in AS 3600—2001, Clause 4.3. Where the exposed underside of BONDEK is subjected to a more severe corrosive environment use a suitable corrosion protection system. In any exposed application, you need to treat the edges of BONDEK to prevent moisture entering between the concrete and the sheeting (Figure 1.2).

1 Introduction
DESIGN FLOWCHART
2 2.1
FORMWORK DESIGN GENERAL New design rules have been developed for the design of LYSAGHT acting as structural formwork for the construction of composite and non-composite slabs (where BONDEK is used as lost formwork). The rules for calculating moment capacities are based on testing performed at BLUESCOPE LYSAGHT Research and Development facility at Chester Hill, AS/NZS 4600:1996, and a finite element strip buckling analysis.
BONDEK
The data obtained allowed us to include moment capacities in negative regions of the design model. As a consequence, the span limits that previously applied to BONDEK have been increased by up to 8%. Formwork design calculations are covered in this section—geometric layout considerations are generally covered in Chapter 5 (Construction).
2.2
APPLICATION Our design tables may be used to detail BONDEK acting as structural formwork, provided the following conditions are satisfied. 1. The support lines extend across the full width of the sheeting and have a minimum bearing of 50 mm at the ends of the sheets, and 100 mm at intermediate supports over which the sheeting is continuous. 2. The sheets continue over each slab span length without any intermediate splicing or jointing. 3. The ratio of the longer slab span (L1) to the shorter slab span (Ls) of any two adjacent spans does not exceed 1.2, that is L1/Ls ≤1.2. 4. Prop lines are positioned at equal spacings (L´) within a span (L) in the case of propped construction. 5. The slab has a uniform cross section. 6. The supports are effectively rigid such that their vertical deflection during the construction phase can be ignored in design. 7.
formwork is not normally cantilevered, though you can seek advice from our information service for special situations.

8. Separate consideration is given to sides of the sheeting where edges are restrained or where the side of the sheeting is cut longitudinally. Equal sheeting spans L’ Outline of concrete

DEFLECTION LIMITS
We recommend a deflection limit of span/240 for the design of composite slabs in which good general alignment is required, so that the soffit has a good visual quality when viewed as a whole. We consider span/240 to be suitable for a Class 3 and 4 surface finish and, in many situations, Class 2. Where alignment affects the thickness of applied finishes (for example vermiculite), you may consider a smaller limit of span/270 to be more suitable. We consider span/150 to be a reasonable maximum deflection limit appropriate for profile steel sheeting in situations where visual quality is not significant (Class 5). The design rules presented may be used for deflection limits other than those stated above however, for deflection greater than span/150, you may contact our information service.
2.4
FORMWORK DESIGN LOADS bondek must be designed as formwork for two stages of construction. Stage I—prior to the placement of the concrete, which includes the time: •
during handling and erection of the formwork; and
•
once the formwork is erected but prior to the placement of the concrete, (Stage I as defined in AS 3610—1995.)
When a live load due to stacked materials can be adequately controlled on the site at less than 4 kPa, the reduced design live load must be clearly indicated on the formwork documentation. Stage II—during placement of the concrete up until the concrete has set (until fcm reaches 15 MPa and concrete is able to act flexurally to support additional loads such as stacked materials). No loads from stacked materials are allowed until the concrete has set. Stage III—as defined in AS 3610—1995 must not be considered in the rules presented here.
2.4.1
DEAD LOAD OF BONDEK SHEETING The dead load of the Gsh = 0.13tbm
BONDEK
sheeting (Gsh) is:
(AS 3610—1995, Clause 4.4.2.1)
(Gshis in kPa, when tbmis in mm)
2.4.2
DEAD LOAD OF CONCRETE The dead load of the concrete (Gc) must include an allowance for the weight of reinforcement as well as the effect of ponding, and is calculated as: Gc = ρ ( D + 0.7∆ )
(AS 3610—1995, Clause 4.4.2.2)
The effect of ponding must be taken as 0.7 times the maximum deflection (∆) of the sheeting when supporting the wet concrete.

2 Formwork design
AS 3610—1995 Formwork for concrete, defines five classes of surface finish (numbered 1 to 5) covering a broad range of applications.
2.4.3
UNIFORM VERTICAL LIVE LOAD The uniform vertical live load (Quv), for the appropriate stage of construction, is: For Stage I construction QuvI = 1.0 kPa
For Stage II construction QuvII = 1.0 kPa
2.4.4
LOAD
(AS 3610—1995, Clause 4.4.2.3)
CONCENTRATED VERTICAL LIVE A concentrated vertical live load (Qc) is: Qc = 3.0 kPa (over an area 1.6 m2 placed at any location)
(AS 3610—1995, Clause 4.4.2.3) Provided the formwork design conforms to this manual, you need not consider concentrated loads as specified in AS 2327.1—1996, Appendix F2.
2.4.5
VERTICAL LIVE LOAD DUE TO STACKED MATERIALS A vertical live load (QM) due to stacked materials is: For Stage I construction QMI = 4 kPa maximum (AS 2327.1—1996 does not allow less than 4 kPa for composite beam construction.) For Stage II construction QMII = 0 kPa
2.4.6
(AS 3610—1995, Clause 4.4.2.4)
LOAD COMBINATIONS FOR STRENGTH The design loads for strength are taken from the following load combinations: For Stage I construction FdI = 1.25Gsh + 1.5QuvI + 1.5QmI
For Stage II construction FdIIa = 1.25Gsh + 1.5Gc + 1.5QuvII FdIIb = 1.25Gsh + 1.5Gc + Qc
2.4.7
(AS 3610—1995, Clause 4.5.4.1)
LOAD COMBINATIONS FOR SERVICEABILITY The design service load for vertical deflection is: Fdef = Gsh + Gc
(AS 3610—1995, Clause 4.5.4.4)

2.4.8
DESIGN FOR STRENGTH Design moments The design positive bending moment (M*+) must be calculated from statics —treating each span as continuous with design negative moments over supports —and not exceed the values shown in Table 2.1.
Design shear The design vertical shear force (V*) must be calculated from statics, treating each span as continuous with design negative moments over supports as shown in Table 2.1. Each load combination for strength must be considered and the concentrated vertical live load (Qc) must be placed in a position which maximises the vertical reaction.

Each load combination for strength must be considered and the concentrated vertical live load (Qc) must be placed in a position which maximises the vertical reaction. Strength of positive moment regions The design positive moment capacity (φMu.sh+) is given in Table 2.1. The capacity is applicable when the loading is applied to the pans, or the tops of the ribs provided the distribution width on the ribs is a minimum of 50 mm. Strength of support regions The design shear capacity (ØVu.sh) for bearing length of 50 mm or more, is: φVu.sh = 33.99tbm 2 + 8.17tbm

the values of the coefficient kd are given in Table 2.2; and

the value of the effective second moment of area Ief is calculated as follows:
Single span sheets Ief / tbm = 205 L = 96025
(for the range of 301025 ≤ Ief / tbm ≤ 508000 ) Multiple span sheets Ief / tbm = 240 ( L or L' ) − 70250
(for the range of 169750 ≤ Ief / tbm ≤ 508000 ) To keep the amount of ponded concrete to a manageable level, the maximum vertical deflection (∆) within any span must not exceed (L or L´ )/150. 9
2 Formwork design
Design negative capacities are significantly less than maximum negative and positive capacities, because negative regions begin to ‘soften’ well before the design positive capacity is reached.

COMPOSITE SLAB DESIGN GENERAL This chapter discusses the parameters upon which our design tables are based. Solutions to your design problems may be obtained by direct reference to either our BONDEK 2003 software, or our design tables. The design solutions are based on partial shear connection theory. Data about the shear connection performance of LYSAGHT BONDEK have been obtained from slip-block tests and full-scale slab tests. Mechanical and frictional resistance have now been identified as the major contributors to the bond, and a composite slab no longer depends on adhesion bond for anchorage. A method of design for vertical shear is also presented. Major savings are achieved by allowing moment redistribution from negative to positive moment regions in continuous composite slabs, and this leads to a significant reduction in the amount of top-face reinforcing. Our design tables assume the use of 500 N-class fire and negative reinforcement. In our composite slab design tables, slab thickness has been developed for FRL60. The tables for continuous slabs have been developed for end spans and can be used for interior spans also. Our BONDEK 2003 software often gives more economical designs.
3.2
CRACK CONTROL OPTIONS An advanced method of crack control for flexure limits the crack width to 0.3 mm. Our design tables assume continuous slabs with flexural cracking control. However, if aesthetics (wide cracks over supports) is not important, it may be economical to design a continuous slab as a series of one-way slabs—no negative reinforcement is necessary in such case (refer to Worked example 1, Chapter 6). Slab design calculations are covered in this section—geometric layout considerations are generally covered in Section 5 (Construction).
3.3
APPLICATION The rules presented can be used to design BONDEK composite slabs provided the following conditions are satisfied. 1. The specified concrete strength grade ƒ´c is in the range 25 MPa to 40 MPa (as specified in AS 3600—2001). The concrete density ρc may be either lightweight (1800 ≤ ρc ≤ 2100 kg/m3) or normal density (2100 ≤ ρc ≤ 2800 kg/m3) (as specified in AS 3600— 1994). 2. The concrete manufacture and materials satisfy the requirements of AS 3600—2001, Section 19. 3. The lines of support extend across the full width of the sheeting and have a minimum bearing of 50 mm at the ends of the sheets, and 100 min at intermediate supports over which sheeting is continuous. 4. The ratio of the longer slab span ( L1) to the shorter slab span ( Ls ) of any two adjacent spans does not exceed 1.2, that is L1/Ls ≤ 1.2. 5. The slab has a uniform cross-section. 6. The design loads for serviceability and strength design must be uniformly-distributed and static in nature.
10
7. The bending moments at the supports are only caused by the action of vertical loads applied to the slab. 8. The exposure classification is A1, A2, B1, or B2. 9. The geometry of the steel sheeting profile must conform to the dimensions and tolerances shown on our production drawings. Sheeting with embossments less than the specified lower characteristic value must not be used compositely unless the value of Hr is revised. 10. Material and construction requirements for conventional reinforcing steel must be in accordance with AS 3600—2001, Clause 19.2, and the design yield stress, ( ƒsy ), must be taken from AS 3600—2001, Table 6.2.1, for the appropriate type and grade of reinforcement, and manufacturers’ data. 11. Material and construction requirements for concrete must be in accordance with AS 3600—2001, Clause 19.1. 12.
must not be spliced, lapped or joined longitudinally in any way.
BONDEK
14. Similar to the requirement in AS 2327.1, Clause 4.2.3, composite action must be assumed to exist between the steel sheeting and the concrete once the concrete in the slab has attained a compressive strength of 15 MPa, that is ƒ´cj ≥ 15 MPa. Prior to the development of composite action during construction (Stage 4 defined in AS 2327.1), potential damage to the shear connection must be avoided; and no loads from stacked materials are allowed. 15. The first interior span must have the same thickness as the end span.

DURABILITY The exposure classification relevant to the design of BONDEK slabs are A1, A2, B1 and B2 as defined in AS 3600—2001, Clause 4.3. The minimum concrete cover (c) to reinforcing steel, measured from the slab top face, must comply with AS 3600—2001, Table 4.10.3.2. These requirements relevant to the design of BONDEK slabs are in Table 3.1. The minimum overall depth (D) of BONDEK slabs must at least comply with the requirements given in Table 3.2. The values take into account the appropriate exposure classification and concrete strength grade ƒ´c. They have been derived assuming that the minimum distance from the top face of the top bar to the soffit of the slab is 70 mm, and that the cover is equal to the appropriate minimum value specified in Table 3.1. Crack control is important for durability where cracks could provide pathways for ingress of corrosive substances such as water, and also for aesthetic reasons. The maximum crack width under long-term serviceability loads must not exceed 0.3 mm.

DESIGN LOADS STRENGTH LOAD COMBINATIONS For strength calculations, design loads for both propped and unpropped construction must be based on the following load combination.

1.25 Gc + Gsh + Gsup + 1.5Q
Or simplified: 1.25G + 1.5Q
Composite slabs are designed assuming one-way action, and therefore reduction of uniformly-distributed live load is not appropriate.
3.5.2
SERVICEABILITY LOAD COMBINATIONS For serviceability calculations other than deflection, design loads are based on the relevant load combination from Table 3.3. Appropriate values of ψs and ψl given in AS 1170.1 are used, depending on the type of building occupancy. Table 3.3 Load combinations for serviceability, excluding deflection

For other cases, appropriate design loads must be derived from the principles of mechanics. Table 3.4 Load combinations for deflection Proped spans

The multiplier for creep and shrinkage ( kcs ) is determined in accordance with AS 3600—2001, Clause 8.5.3.3. The ratio Asc /Ast , is obtained by dividing the area of conventional reinforcement in compression by the area of all reinforcement in tension, including sheeting and conventional reinforcement, making no allowance for the different design yield stresses of the steels involved. Where: kcs = 2 − 1.2

For deflections in concrete-frame buildings, refer to Section 3.12. 12
3.5.4
LIGHTWEIGHT CONCRETE LOAD Our design tables assume the use of normal density concrete (2100 < ρc ≤ 2800 kg/m3) as specified in AS 3600—2001. They may also be conservatively used for lightweight concrete (1800 < ρc ≤ 2100 kg/m3). Use BONDEK 2003 for more economical solutions.
3.5.5
SUPERIMPOSED DEAD LOAD The maximum superimposed dead load assumed in our design tables is 1 kPa. However bigger loads might be considered in some design situations. It is possible to treat additional superimposed dead loads as factored live load: Qadditional = 2 Gin excess of 1 kPa Use

BONDEK
(see Worked example 3)
2003 for more economical solutions.
For strength and serviceability calculations, the linear elastic analysis method of AS 3600—2001, Clause 7.6, must be used to determine design bending moments and vertical shear forces. In calculating action effects in slabs which are continuous over beams, the vertical flexibility of the supporting beams must be small enough to be ignored. For strength calculations, redistrib-ution of moments are permissible up to the limit defined in AS 3600—2001, Clause 7.6.8, with the following exceptions: •
The redistribution limit in each negative moment region is based on the value of ku in that particular negative-moment region only.
•
Redistribution of moments is permitted from negative-moment regions to positive-moment regions but not from positivemoment regions to negative-moment regions.
•
No redistribution of moments are permissible where the contribution of class 450F and D500L reinforcement (low ductility) has been included in the calculation of the design negative moment capacity.
The ductility requirements of AS 3600—2001, Clause 7.6.8, need not be applied to the positive-moment regions of BONDEK slabs. For strength calculations, the inclusion of pattern variations of live load results in a bending moment envelope in which some regions are both negative-moment regions and positive-moment regions. These regions must comply with the requirements for both types of region. For serviceability calculations, pattern live loads must be included for short-term live loads but excluded for long-term live loads.

DESIGN FOR STRENGTH IN NEGATIVE-MOMENT REGIONS For strength calculations in negative-moment regions use the detailed procedure in Design of composite slabs for strength (Design booklet DB3.1, BHP, 1998).
3.7.1
MINIMUM BENDING STRENGTH The minimum bending strength requirement of AS 3600—2001 must be satisfied at all potential hinge locations in negative-moment regions—thus, conventional tensile reinforcement must be provided to ensure that: Muo − ≥ 1.2 Mcr −
Where: •
The negative moment region is part of a cantilever; and
•
Class 450F or D500L reinforcement is used to provide negative moment capacity.
3.7.2
SHEAR STRENGTH Negative-moment regions must be designed for shear strength, to satisfy AS 3600—2001, Section 9. The negative-moment regions of a composite slab can be treated as solid reinforced-concrete sections.
3.7.3
DETAILING OF CONVENTIONAL TENSILE REINFORCEMENT Conventional tensile reinforcement in negative-moment regions must be detailed in accordance with the relevant requirements for one-way slabs in AS 3600—2001, Clause 9.1.3. Pattern 1 Negative-moment regions must be designed to satisfy the requirements of AS 3600—2001, Section 9. The composite slab negative-moment regions can be treated as solid reinforcedconcrete sections.

When live loads exceed twice the dead load (red, bold figures in our design tables), at least one third of negative reinforcement must continue over a whole span. Shrinkage and fire reinforcement, laid on the top, can be assumed to contribute to that additional one third of negative reinforcement.
3.7.4
BENDING STRENGTH For the strength design of negative-moment regions, the presence of the sheeting in the slab is ignored and the slab designed as an equivalent solid reinforced-concrete member. For this purpose, use the provisions of AS 3600—2001 as they relate to the design of oneway slabs. For a slab which is continuous over any support, but treated as simply-supported for strength at that support, the design negative bending moment at the support ( M*– ) must be taken equal to zero. In calculating the design negative bending moment ( M*– ) an allowance may be made for negative-to-positive moment redistribution up to the limit specified in AS 3600—2001, Clause 7.6.8. Thus, the elastic design bending moment before redistribution ( M*–e ) may be reduced in magnitude to obtain the design negative bending moment after redistribution ( M*– ). The nominal negative moment capacity ( Muo– ) is calculated based on the principles of rectangular stress block theory as defined in AS 3600—2001, Clause 8.1.2. For potential hinge locations at which the neutral axis parameter ( ku– ), as defined in AS 3600—2001, exceeds 0.4, the requirements of AS 3600—2001, Clause 8.1.3 must be satisfied. In the application of this clause, it may be assumed that the minimum compressive reinforcement requirement is satisfied by the presence of the steel sheeting in the negative moment region. When applying AS 3600—2001, Clause 7.6.8, be sure that: •
redistribution is normally only allowed if Class N or Class Y (as opposed to Classes L or F) reinforcement is used over the supports;
•
the elastic bending moment distribution before redistribution is determined assuming uncracked cross-sections; and
•
the amount of redistribution is measured by the percentage of the moment before redistribution. 15

3.8
DESIGN FOR STRENGTH IN POSITIVE-MOMENT REGIONS For strength calculations in positive-moment regions use the detailed procedure in Design of composite slabs for strength (Design booklet DB3.1, BHP, 1998).
3.8.1
MINIMUM BENDING STRENGTH The minimum bending strength requirement of AS 3600—2001, Clause 8.1.4.1 must be satisfied at all potential hinge locations in positive-moment regions, that is, Muo + ≥ 1.2 Mcr + . The steel proportion for rectangular cross-sections deemed to satisfy this requirement under Clause 8.1.4.1 must not be used. The contribution of both the sheeting and the conventional reinforcement must be included in the calculation of Muo+.
3.8.2
SHEAR STRENGTH Positive-moment regions must be designed for vertical shear strength, such that at every cross-section located at distance of at least D from the face of a support, the design positive vertical shear capacity ( φVuc+ ), is not less than the design positive vertical shear force ( V*+ ). The design positive vertical shear capacity ( φVuc+ ) may be calculated in accordance with Design of composite slabs for strength (Design booklet DB3.1, BHP, 1998).
3.8.3
DETAILING OF CONVENTIONAL TENSILE REINFORCEMENT The termination locations of any conventional tensile reinforcement in positive-moment regions must be determined by extending the reinforcement a distance D + Lsy.t past the point at which it is no longer required for strength. The requirements of AS 3600—2001, Clause 9.1.3 do not apply. To allow the concrete to flow into place, the minimum clear distance between parallel bars should be restricted to the larger of either 1.5 times the maximum nominal size of aggregate (normally the maximum aggregate size is 20 mm), or the diameter of the largest reinforcing bar.
3.8.4
BENDING STRENGTH Positive-moment regions are designed for bending strength such that at every cross-section the design positive moment capacity ( φMuo+ ) is not less than the design positive bending moment ( M*+ ). For slabs analysed using linear elastic analysis, the design positive bending moment ( M*+ ) is calculated such that equilibrium is maintained after accounting for any redistribution of moments. The design positive moment capacity ( φMuo+ ) within the slab at each cross-section may then be calculated on the basis of either a complete or partial shear connection, as appropriate. In calculating the design positive moment capacity ( φMuo+ ) at any slab cross-section, the entire cross-sectional area of the sheeting is assumed to be available to act as longitudinal reinforcement, with its effectiveness at any particular cross-section being dependent on the degree of shear connection. Conventional longitudinal tensile and compressive reinforcement may be considered to contribute to the positive moment capacity at a cross-section, provided due allowance is made for the required development length for anchorage of the reinforcement in accordance with AS 3600—2001, Section 13.
16
The design positive moment capacity ( φMuo+ ) may be calculated in accordance with Design of composite slabs for strength (Design booklet DB3.1, BHP, 1998).
3.9
DESIGN FOR STRENGTH IN MULTIPLE SPANS Our design tables have been worked out for end spans of continuous slabs. The data in the tables can be used for interior spans also, assuming uniform thickness for end an interior spans. BONDEK 2003 will give more economical solutions for interior spans, and also offers the opportunity to design interior spans with reduced thickness as compared with end spans.
3.10
DESIGN OF REINFORCEMENT OTHER THAN CLASS D500N
It is possible to replace D500N negative reinforcement with D500L, 400Y or 450F grades, increasing the area of reinforcement by the factors shown in Table 3.5. The area of reinforcement required is a function of: •
yield stress;
•
moment redistribution (not allowed for 450F and D500L); and
•
crack control (small diameter bars are more effective).
2003 will give more economical solutions and allow more design flexibility using other diameters and grades.

DESIGN FOR SERVICEABILITY VERTICAL DEFLECTIONS Deflection limits must be selected appropriate to the intended use of the slab. These limits must not exceed those listed in AS 3600— 2001, Table 2.4.2. In that table the reference to members supporting masonry partitions is taken to refer to slabs supporting any deflection-sensitive finishes. (Incremental deflection is the deflection which occurs after the addition or attachment of supporting masonry partitions.) Immediate deflections are calculated in accordance with the simplified method. Incremental and total deflections must be calculated as for immediate deflections, using the appropriate corresponding load combinations from Clause 3.6.3 of this manual. Contributions of sheeting and conventional reinforcement must be included in the calculation of Ief.
17
3 Composite slab design
Our design tables have been worked out for 10 mm diameter D500N reinforcement bars for negative reinforcement.
As a guide for calculation of Ief you may use: •
Crack control of beams (Design booklet RCB-1.1(1), BHP, 2000);
•
Rules for limit-state design to Australian Standards of simplysupported and continuous BONDEK composite slabs in steel-frame or masonry wall buildings (BHPR/SM/R/005, 1996); and
•
Rules for design to Australian Standards of BONDEK composite slabs in concrete-frame buildings (Report No. BHPR/R/1998/066).
3.11.2
CRACK CONTROL FOR SHRINKAGE AND TEMPERATURE EFFECTS For bondek slabs with an overall depth (D) not exceeding 250 mm, the one layer of transverse reinforcement is required at any height within the cover slab provided the appropriate concrete cover is maintained. However, our design tables, and BONDEK 2003, have been developed assuming shrinkage reinforcement is placed at the top for continuous slabs, and at the bottom for single spans. For single spans, longitudinal reinforcement must be located as specified for Fire Detail 2 (Chapter 4). This may result in reduced slab thickness, and less negative and fire reinforcement. Major bars of shrinkage reinforcement mesh must run across BONDEK ribs. Using D500N as shrinkage reinforcement (say N10 at 200 mm x N10 at 200 mm) will always reduce both negative and fire reinforcement—for short spans, it may even eliminate it. This is due to the normal ductility of D500N which can be treated as fire reinforcement and negative reinforcement with moment redistribution. You will have to run BONDEK 2003 for this option.

Determine the cross-sectional area of transverse reinforcement required to control cracking of the cover slab, due to shrinkage and temperature effects, by: •
using AS 3600—2001, Clause 9.4.3.4 (Reinforcement in the secondary direction in restrained slabs); and
•
substituting the overall slab depth (D) with the cover slab depth (D – hr ) in the equations for the minimum cross-sectional area of transverse reinforcement.
Cross-references of OneSteel’s mesh specifications with Grade 450 fabrics are shown in Table 3.7.
3.11.3
CRACK CONTROL FOR FLEXURE For crack control of slabs in flexure, we recommend that you follow OneSteel’s specifications: Crack control of slabs, Part 1: AS 3600 Design (Design Booklet RCB-2.1(1).
The crack control for flexure may not always be required, which is often the case for A1 exposure classification, and when aesthetics are not important. A continuous slab in such conditions may be designed as a series of simply-supported slabs without any negative reinforcement, or as a continuous slab with negative reinforcement designed without crack control, depending on which option is more economical.
3.11.4
END SLIP CONTROL Check each span to ensure that no sheeting end-slip occurs under the loading for short-term serviceability, as follows: •
Under the loading for strength, determine the critical cross section in the positive-moment region, which is the cross-section at which M* / ( φMuo ) is the greatest. (The critical cross-section is where a major crack is assumed to open, thus causing the test block to slip towards the end.)
•
At the critical cross section in the positive-moment region, determine the distance to the nearer end of the sheeting, xend.
•
Calculate the limiting force in the sheeting to produce end slip from the equation: Tslip = 200 xend
Where: Tslip is expressed in kN and xend in metres. (Value of 200 is obtained from tests as an ‘average’ value.) •
Under the loading for short-term serviceability, determine the moment at the critical cross section in the positive-moment region ( Mss ) and calculate the force in the sheeting ( Tss ) from cracked elastic analysis of the cross-section. For this purpose, the properties of the sheeting may be considered to be acting in a plane 15 mm above the soffit of the slab.
•
Ensure that there is no end slip between the sheeting and concrete under service loads. To do this check that Tss ≤ Tslip and, if necessary, alter the design for strength of the span (for example: increase Dc and maybe tbm).

3 Composite slab design
Since maximum steel stress in cracked sections is a function of a bar diameter, the bar diameter in our tables is 10 mm (the minimum possible for D500N reinforcement).
3.12
DESIGN FOR CONCRETE-FRAME BUILDINGS This section covers design of slabs spanning between wide reinforced-concrete beams (band-beams) or prestressed bandbeams of concrete-frame buildings. Other forms of concrete-frame constructions, such as slabs spanning between ‘narrow’ reinforced concrete beams, or reinforced concrete walls, may be designed using the rules for steel-frame and masonry wall buildings. Use Rules for design to Australian Standards of Bondek composite slabs in concrete-frame buildings (BHP R/R/1998/006). Our design tables assume the use of steel-frame or masonry wall buildings. However, they may be used for concrete-frame buildings, with the following restrictions: •
The sheeting end must penetrate at least 25 mm into the concrete cover on the side of a concrete beam formed up with temporary formwork (Figure 3.3).
•
Table 3.8 Where BONDEK terminates, bending moments must be zero or Area of anchorage reinforcement as a negative for all loading combinations. If the moments are percentage of negative reinforcement positive (BONDEK is in tension), additional bottom anchorage Percentage of negative reinforcement reinforcement must be designed (Figure 3.3 and Table 3.8). Interior End supports with Bottom fire reinforcement Detail 2 can be treated as anchorage w/L supports band beams reinforcement. Development lengths must be designed % % according to AS 3600—2001, Section 13. ≤0.1 Not required 12
•
Vertical flexibility of the support beams must be small enough to be ignored.
Our tables don’t allow for any beneficial effect on deflections and propping requirements by band-beams. Run BONDEK 2003 for more economical solutions yielding thinner slabs and fewer props. For the design of concrete-frame buildings, use the following rules in addition to those of steel-frame or masonry wall buildings: •
Calculate the immediate deflections in accordance with the simplified method as defined in AS 3600—2001, Clause 8.5.3.1, but don’t use the method of averaging Ief over several crosssections. Determine the values of Ief at an appropriate number of selected cross-sections referring to the shape of the momentcurvature diagram for the member to enable deflections to be calculated by integration of curvatures along the length. The curvature at each cross-section is obtained by dividing the bending moment by EcIef.
•
Calculate the nominal positive moment capacity ( Muo+ ) at crosssections within the band-beam using conventional reinforcedconcrete design methods in accordance with AS 3600—2001.

FIRE DESIGN GENERAL This chapter discusses the parameters relating to the exposure of the soffit to fire, upon which our design tables are based. Solutions to your design problems may be obtained by direct reference to either our design tables, or our BONDEK 2003 software. The software has enhanced fire design module which allows BONDEK sheeting to be partially effective during fire for up to 2 hours. Software will give more economical results. Guide tables in this manual have not been modified for enhanced fire design. Reduction factors are applied to allow for the effect of temperature on the slab materials and slab cross-section. Values of these reduction factors have been derived from extensive analysis of BONDEK slab cross-sections. These reduction factors account for the adverse effect of elevated temperatures on the mechanical properties of concrete and steel, and also include the effect of thermally induced stresses caused from the temperature gradient across the section, resulting in differential thermal expansion.
The distribution of temperature through a cross-section of a composite slab subject to fire, is affected by the geometry of the sheeting profile (Figure 4.1). The features important in the sheeting profile are: the rib geometry (shape, height and spacing of intermediate ribs and lapping ribs), and the pan geometry (such as stiffening flutes). Fire design calculations are covered in this section—geometric layout considerations are generally covered in Section 5 (Construction).

APPLICATION Our fire design tables may be used to detail BONDEK composite slabs when the soffit is exposed to fire provided the following conditions are satisfied. 1. The composite slab acts as a one-way element spanning in the direction of the sheeting ribs for both room temperature and fire conditions. 2. The composite slab has been initially designed and detailed for room temperature conditions in accordance with this manual. 3. The fire design load is essentially uniformly distributed and static in nature. 4. Transverse reinforcement for the control of cracking due to shrinkage and temperature effects is provided. 5. Adequate detailing of slab jointing, edges, slab holes and cavities (for penetrating, embedded or encased services) to provide the appropriate fire resistance period. Alternatively the local provision of suitable protection (such as fire spray material) will be necessary. 6. The fire cases are for periods of 60, 90, 120 or 180 minutes. 7. Reinforcement conforms to Section 4.6 of this manual.
4.3
FIRE RESISTANCE PERIODS Four fire cases are considered. In each fire case the fire resistance periods for structural adequacy, integrity and insulation are taken to be of equal duration. The fire cases considered are:
4.4
•
Fire case F60 = FRL 60/60/60
•
Fire case F90 = FRL 90/90/90
•
Fire case F120 = FRL 120/120/120
•
Fire case F180 = FRL 180/180/180

POTENTIALLY CRITICAL CROSS-SECTIONS All potentially critical cross sections at which hinges may form must be identified (Figure 4.2) and checked for strength. All negative moment hinges may be assumed to be plastic under fire conditions. These cross sections correspond to where: •
negative moments are a maximum over supports;
•
negative tensile reinforcement is curtailed;
•
positive bending moment is a maximum; or
•
at any changes in cross section (for example changes in depth or where there is a significant hole through the slab). Assumed critial cross-sections

STRENGTH OF POSITIVE MOMENT REGIONS At the potentially critical cross section where the positive moment is a maximum, the design strength in bending ( φMuoT+ ) is determined for the given period of fire exposure as follows: R A f φ MuoT,i + = φ Rst Ast fsy d + 1 − 0.6 st +st sy bd f ' c Where:

Linear interpolation may be used to determine values of Rst for intermediate values of yb. 2. Position of longitudinal bottom face reinforcement with respect to the rib centre and the soffit of the slab is shown in Figure 4.2. 3. For a fire-resistance period of 30 minutes, the bending strength of the composite slab cross-section, due to the effects of heating, is unlikely to be affected significantly. However, for design, you may use a fire resistance period of 60 minutes.
The form of this equation is identical with that used to calculate the design strength in bending of under-reinforced concrete crosssections at room temperature conditions, but makes allowance for the influence of temperature on the strength of the reinforcing steel. Similar procedure shall be used to calculate additional capacity due to BONDEK being particularly effective against fire. Reinforcement used to control shrinkage and temperature effects often provides adequate fire resistance. It is normal to ignore the small design strength in positive bending associated with any continuous top face reinforcement, however on some projects this may be sufficient to provide an equilibrium state without the need to provide any additional reinforcement. At the end of the fire period the value of kuT+ where the positive moment is a maximum: kut + =

Where: The reduction factor ( Rst ) is given in Table 4.2; and γ = [0.85 - 0.007 (f´c – 28)] within the limits of 0.65 to 0.85, and f´c must be in MPa (AS 3600—2001, Clause 8.1.2.2).
4.5.4
STRENGTH OF NEGATIVE MOMENT REGIONS At the potentially critical cross sections associated with negative moments over supports, or where the negative steel is curtailed, the design strength in bending ( φMuoT+ ) for the given period of fire exposure is: φ MuoT,i − = φ Rst Ast − fsy ( d − − dx )
Where: The reduction factor Rst is given in Table 4.2; and dx is given in Table 4.3. This equation takes into account the adverse effect of elevated temperatures on the compressive strength of the concrete in the slab soffit, and also includes the effect of thermally induced stresses.
4.5.5
CHECK FOR STRUCTURAL ADEQUACY The structural adequacy of the end, interior or simple spans must be checked for the assumed period of fire exposure. Do this by finding an equilibrium state whereby—under the applied loads ( ωf ) — the bending moments ( Mz ) at the potentially critical cross sections, do not exceed the relevant values of positive and negative design bending strength φMuoT+ and φMuoT– respectively. Interior spans (Figure 4.2) The bending moment distribution along an interior span for an assumed pair of plastic hinges at potentially critical cross sections in negative bending can be expressed as:

REINFORCEMENT FOR FIRE DESIGN The arrangement of reinforcement for fire design is shown in Figure 4.5. Fire reinforcement is essential, in addition to any negative reinforcement required by our tables for composite slab design. The temperature and shrinkage reinforcement of grades D500N, 400Y or 450F can be treated as fire reinforcement if located and detailed in accordance with Figure 4.5—it may significantly reduce fire reinforcement, or even eliminate it. The location of reinforcement Ast.f– for Fire detail 1 is in a single top layer at a depth of dct below the slab top face (Figure 4.5). This detail is applicable to end and interior spans only. The location of reinforcement Ast.f+ for Fire detail 2 is in a single bottom layer at a distance of yb above the slab soffit (Figure 4.5). This detail is applicable to end spans, interior spans and simple spans. The fire reinforcement Ast.f+ must be continuous over interior supports. Concrete

The cross-sectional area of the additional reinforcement for fire design is designated Ast.f in our tables (D500N with φ ≥ 10 mm). The negative reinforcement ( Ast– ) and the additional fire reinforcement ( Ast.f+ or Ast.f- as applicable), must be located a distance xb minimum from the centre of any rib. D500N, 450F or 400Y reinforcement can be used for fire design. D500L reinforcement is not allowed as negative reinforcement in fire designs. The limitation is due to hinge formation requirements, which may not be satisfied with only 1.5% uniform elongation for D500L. Further research may be needed to determine the suitability of D500L reinforcement for fire design. D500N fire reinforcement may be replaced with 400Y or 450F grades, increasing the area of reinforcement by the factors shown in Table 4.4.

CONSTRUCTION The construction of LYSAGHT BONDEK composite slabs follows simple, familiar and widely-accepted building practice. Workers can readily acquire the skills necessary to install BONDEK formwork and finish the composite slab. Construction workers will normally be supplied with fully detailed drawings showing the direction of the ribs, other reinforcement and all supporting details.
5.1
SAFETY is available in long lengths, so large areas can be quickly and easily covered to form a safe working platform during construction. One level of formwork gives immediate protection from the weather, and safety to people working on the floor below. The minimal propping requirements provide a relatively open area to the floor below.
BONDEK
The bold embossments along the top of the ribs of BONDEK enhance safety by reducing the likelihood of workers slipping. Some LYSAGHT centres, may supply BONDEK with knurling on the upper face of the flutes, which provides even more safety against slippage. It is commonsense to work safely, protecting yourself and workmates from accidents on the site. Safety includes the practices you use; as well as personal protection of eyes and skin from sunburn, and hearing from noise. For personal safety, and to protect the surface finish of BONDEK, wear clean dry gloves. Don’t slide sheets over rough surfaces or over each other. Always carry tools, don’t drag them. Occupational health and safety laws enforce safe working conditions in most locations. Laws in every state require you to have fall protection which includes safety mesh, personal harnesses and perimeter guardrails where they are appropriate. We recommend that you adhere strictly to all laws that apply to your site. is capable of withstanding temporary construction loads including the mass of workmen, equipment and materials all in accordance with AS 3610—1995. However, it is good construction practice to ensure protection from concentrated loads, such as barrows, by use of some means such as planks and/or boards.
BONDEK
CARE AND STORAGE BEFORE INSTALLATION is delivered in strapped bundles. If not required for immediate use stack sheets or bundles neatly and clear of the ground, on a slight slope to allow drainage of water. If left in the open, protect with waterproof covers.

5.3.1
PROPPING Depending on the span of a bondek slab, temporary propping may be needed between the slab supports to prevent excessive deflections or collapse of the formwork. formwork is normally placed directly on prepared propping. Props must stay in place during the laying of BONDEK formwork, the placement of the concrete, and until the concrete has reached the strength of 15 MPa. BONDEK
Propping generally consists of substantial timber or steel bearers supported by vertical props. The bearers must be continuous across the full width of BONDEK formwork. Where the underside of bondek formwork is featured as a finished ceiling, wide form-ply strips attached to the bearers will minimise marking. The width of the form-ply strips depends upon the slab depth, BONDEK metal thickness and spans. Form-ply strips of 300 mm width have been used successfully. Propping must be adequate to support construction loads and the mass of wet concrete. The number of props you need for given spans is shown in our tables.
5.3.2
LAYING must be laid with the sheeting ribs aligned in the direction of the designed spans. Other details include the following.
BONDEK
•
The slab supports must be prepared for bearing and slip joints as required.
•
Lay BONDEK sheets continuously over each slab span without any intermediate splicing or jointing.
•
Lay BONDEK sheets end to end. Centralise the joint at the slab supports. Where jointing material is required the sheets may be butted against the jointing material.
•
Support BONDEK sheets across their full width at the slab support lines and at the propping support lines.
•
For the supports to carry the wet concrete and construction loads, the minimum bearing is 50 mm for ends of BONDEK sheets, and 100 mm for intermediate supports over which the sheeting is continuous.
•
Props where required
In exposed applications, treat the end and edges of the sheets with a suitable edge treatment to prevent entry of moisture.

5.3.3
INTERLOCKING OF SHEETS Overlapping ribs of BONDEK sheeting are interlocked. Either of two methods can be used in most situations, though variations may also work.
Method 1 Position Bondek sheet parallel with previously-laid sheet. Interlock sheets by applying pressure to either position.
In the first method, lay adjacent sheets loosely in place. Place the female lap rib overlapping the male lap rib of the previous sheet and apply foot pressure, or a light kick, to the female lap rib (Figure 5.2). In the second method, offer a new sheet at an angle to one previously laid, and then simply lower it down, through an arc (see Figure 5.2).
Method 2 Position Bondek sheet at an angle. Interlock sheets by lowering sheet through an arc.
If sheets don’t interlock neatly (perhaps due to some damage or distortion from site handling or construction practices) use screws to pull the laps together tightly (see Section 5.3.8, Fastening side-lap joints).
5.3.4
SECURING THE PLATFORM Once laid, BONDEK provides a stable working platform. Where additional security is needed (to prevent movement from construction activities and from wind) you can use:
Figure 5.2 Two methods of interlocking adjacent BONDEK sheets
•
weights;
•
screws or nails into the propping bearers; or
•
BONWEDGE and underneath.
BON-NUT
suspension systems pulling down from
Take care if you use penetrating fasteners (such as screws and nails) because they can make removal of the props difficult, and perhaps result in damage to the BONDEK.
5.3.5
INSTALLING BONDEK ON STEEL FRAMES BONDEK
may be installed directly on erected structural steelwork.
General fastening of bondek To provide uplift resistance or lateral restraint, the sheeting may be fixed to the structural steel using spot welds, or fasteners such as drive nails or self-drilling screws.
Place the fixings (fasteners and spot welds) in the flat areas of the pans adjacent to the ribs or between the flutes. The frequency of fixings depends on wind or seismic conditions and good building practice. Fixing at end of sheets
Fixing at intermediate slab supports over which the sheeting is continuous
Figure 5.3 Positions for fixing Bondek to steel framing
One fixing system is as follows. •
At the end of sheets: use a fixing at every rib (Figure 5.3).
•
At each intermediate slab support over which the sheeting is continuous: use a fixing at the ribs on both edges (Figure 5.3).
•
Fix
•
Drive nails should be powder-activated, steel nails 4 mm nominal diameter, suitable for structural steel of 4 mm thickness or greater.
•
For structural steel up to 12 mm thick, use 12-24 x 38 mm selfdrilling hexagon head screws.
•
For structural steel over 12 mm thick, pre-drill and use 12-24 x 16 mm hexagon head screws.
BONDEK

5 Construction
At a movement joint, the sheeting is not continuous over the support. If one sheet is fastened at the joint, the other is not.
•
Spot welds should be 12 minimum diameter. Use 3.25 mm diameter cellulose, iron powder AC/DC high penetration electrodes. Surfaces to be welded must be free of loose material and foreign matter. Where the bondek soffit or the structural steelwork has a pre-painted surface, securing methods other than welding may be more appropriate. Take suitable safety precautions against fumes during welding zinc coated products.
Fastening composite beams In projects of composite beam construction the bondek sheeting must be fastened in accordance with AS 2327, Clause 9.2 (Composite beams with slabs incorporating profiled steel sheets). This provision requires a fixing in each pan at each composite beam. Stud welding through the sheet has been considered a suitable securing method for the sheeting in a composite beam; however some preliminary fixing by one of the methods mentioned above is necessary to secure the sheeting prior to the stud welding. Stud welding should comply with the requirements of AS 1554, Part 2 and AS 2327, Part 1. Some relevant welding requirements are:
5.3.6
•
Zinc coating on sheeting not to exceed Z450;
•
Mating surfaces of steel beam and sheeting to be cleaned of scale, rust, moisture, paint, overspray, primer, sand, mud or other contamination that would prevent direct contact between the parent material and the bondek;
•
Welding must be done in dry conditions by a certified welder;
•
For pre-painted bondek sheets, special welding procedures may be necessary; and
•
For sheets transverse to beams, Stud welding must be between pan flutes to ensure there is no gap between mating surfaces.
INSTALLING BONDEK ON BRICK SUPPORTS Brick walls are usually considered to be brittle and liable to crack from imposed horizontal loads. Thermal expansion and contraction, long-term shrinkage, creep effects and flexural deflection of concrete slabs may be sufficient to cause such cracking. Bondek and reinforcement are not continuous through the movement joint

To prevent the cracking, BONDEK slabs are not usually installed directly on brick supports, although this is not always the case in earthquake construction. Slip joints Generally, a slip joint is provided between bondek and masonry supports (Figure 5.4). •
No fasteners are used between bondek and its support at a slip joint.
•
Slip joint material may be placed directly in contact with the cleaned surface of steelwork.
•
The top course of masonry should be level, or finished with a levelled bed of mortar to provide an even bearing surface. Lay the top courses of bricks with the frogs facing down.
•
The width of a slip joint should not extend beyond the face of the slab support.
•
The slip joint material must have adequate compressive strength to avoid it being compressed into irregularities of the mating surfaces and thus becoming a rigid joint.
Slip joint material must allow movement to occur, usually by allowing flow under pressure or temperature, however it must not run or solidify. Generically, the materials are a non-rotting, synthetic carrier impregnated with a neutral synthetic or petroleum-based material. Typical slip joint material is Alcor (a bitumen coated aluminium membrane).

INSTALLING BONDEK ON CONCRETE FRAMES When used in concrete-frame construction, the BONDEK sheeting is discontinuous through the supports (Figure 5.5). Concrete

CONSTRUCTION AND MOVEMENT JOINTS Joints used between BONDEK slabs generally follow accepted construction practices. Construction joints are included between slabs for the convenience of construction. Movement joints allow relative movement between adjoining slabs. The joints may be transverse to, or parallel with, the span of the BONDEK slab. Movement joints need a slip joint under the BONDEK sheeting. (Figure 5.4). Joints typically use a non-rotting, synthetic carrier impregnated with a neutral synthetic or petroleum based material like Malthoid (a bitumen impregnated fibre-reinforced membrane). Sometimes a sealant is used in the top of the joint for watertightness. The BONDEK sheeting and any slab reinforcement are not continuous through a joint. Design engineers generally detail the location and spacing of joints because joints effect the design of a slab. 33

5.3.9
FASTENING SIDE-LAP JOINTS If BONDEK sheeting has been distorted in transport, storage or erection, side-lap joints may need fastening to maintain a stable platform during construction, to minimise concrete seepage during pouring, and to gain a good visual quality for exposed soffits (Figure 5.6).

CUTTING AND FITTING EDGE FORM EDGE FORM is a simple C-shaped section that simplifies the installation of most BONDEK slabs. It is easily fastened to the BONDEK sheeting, neatly retaining the concrete and providing a smooth top edge for quick and accurate screeding. We make it to suit any slab thickness. EDGE FORM is easily spliced and bent to form internal and external corners of any angle and must be fitted and fully fastened as the sheets are installed. There are various methods of forming corners and splices. Some of these methods are shown in Figures 5.7 and 5.8.
Fasten EDGE FORM to the underside of unsupported BONDEK panels every 300 mm. The top flange of edge form must be tied to the ribs every 600 mm with hoop iron 25 mm x 1.0 mm (Figures 5.7 and 5.16). Use 10–16 x 16 mm self-drilling screws. Make sure that the zinc coating on EDGE FORM matches the corrosion protection requirements of your job (see Section 1.10 Corrosion protection). External corner 1. Notch top flange for the required angle
3. Bend corner of Edge Form to the required angle, overlapping bottom flanges.
2. Cut 'V' in bottom flange
Internal corner 2. Bend Edge Form to required angle. 1. Cut top and bottom flanges square.

SEALING Seepage of water or fine concrete slurry can be minimised by following common construction practices. Generally gaps are sealed with waterproof tape or by sandwiching contraction joint material between the abutting ends of BONDEK sheet. If there is a sizeable gap you may have to support the waterproof tape, and BONFILL may be found useful (Figure 5.9).

ITEMS EMBEDDED IN SLABS Generally use items in a manner which complies with AS 3600— 2001, Clause 14.2 (Embedded items and holes in concrete), and Clause 14.3 (Requirements for fixings). Included are pipes and conduits, sleeves, inserts, holding-down bolts, chairs and other supports, plastic strips for plasterboard attachment, contraction joint material and many more.

HOLES acts as longitudinal tensile reinforcement similarly to conventional bar or fabric reinforcement does in concrete slabs. Consequently, holes in BONDEK sheets, to accommodate pipes and ducts, reduce the effective area of the steel sheeting and can adversely effect the performance of a slab.

INSPECTION We recommend regular qualified inspection during the installation, to be sure that the sheeting is installed in accordance with this publication and with good building practice.
5.3.15
CUTTING It is easy to cut BONDEK sheets to fit. Use a power saw fitted with an abrasive disc or metal cutting blade. Initially lay the sheet with its ribs down, cut through the pans and part-through the ribs, then turn the over and finish by cutting the tops of the ribs.
5.4
REINFORCEMENT sheeting acts as longitudinal tensile reinforcement. The condition of sheeting should be inspected before concrete is poured.
BONDEK
Reinforcement in slabs carries and distributes the design loads and to control cracking. Reinforcement is generally described as transverse and longitudinal in relation to span, but other reinforcement required for trimming may be positioned in other orientations. Figure 5.12 shows a typical cross-section of a BONDEK composite slab and associated terms. Reinforcement must be properly positioned, lapped where necessary to ensure continuity, and tied to prevent displacement during construction. Fix reinforcement in accordance with AS 3600—2001, Clause 19.2.5 (Fixing). To ensure the specified minimum concrete cover, the uppermost layer of reinforcement must be positioned and tied to prevent displacement during construction (Section 3.4 Durability). Splicing of conventional reinforcement must be in accordance with AS 3600—2001, Clause 13.2 (Splicing of reinforcement). Where fabric is used in thin slabs, or where fabric is used to act as both longitudinal and transverse reinforcement, pay particular attention the required minimum concrete cover and the required design reinforcement depth at the splices—splice bars are a prudent addition.

5 Construction
Always place chairs and spacers on pan areas. Depending upon the type of chair and its loading, it may be necessary to use plates under chairs to protect the BONDEK, particularly where the soffit will be exposed. Transverse reinforcement may be used for spacing or supporting longitudinal reinforcement.
5.4.1
TRANSVERSE REINFORCEMENT Transverse reinforcement is placed at right-angles to the ribs of bondek. Deformed bar or fabric reinforcement may be used. In most applications the transverse reinforcement is for the control of cracks caused by shrinkage and temperature effects, and for locating longitudinal reinforcement. To control flexural cracking in the top face of the slab, transverse reinforcement in the top-face may be required over walls or beams which run in the same direction as the BONDEK sheets. For ease of construction, reinforcement for control of cracking due to shrinkage and temperature is usually fabric reinforcement (Section 3.11.3, Crack control for flexure).
5.4.2
LONGITUDINAL REINFORCEMENT Longitudinal reinforcement is positioned to carry design loads in the same direction as the ribs of BONDEK. Deformed bar or fabric reinforcement may be used. Design information is in Chapters 2, 3 and 4. Top-face longitudinal reinforcement is usually located over interior supports of the slab and extends into approximately a third of the adjoining spans. Bottom-face longitudinal reinforcement is located between supports of the slab but, depending upon the detailing over the interior supports, it may be continuous, lapped, or discontinuous. Bottomface longitudinal reinforcement may be placed on top of or below transverse reinforcement. Location of bottom-face longitudinal reinforcement in elevated temperatures requires special design (Figures 4.5 and 4.6).
5.4.3
TRIMMERS Trimmers are used to distribute the design loads to the structural portion of the slab and/or to control cracking of the concrete at penetrations, fittings and re-entrant corners. Deformed bar or fabric reinforcement may be used. Trimmers are sometimes laid at angles other than along or across the span, and generally located between the top and bottom layers of transverse and longitudinal reinforcement. Trimmers are generally fixed with ties from the top and bottom layers of reinforcement.
5.5 5.5.1
CONCRETE SPECIFICATION The concrete is to have the compressive strength as specified in the project documentation and the materials for the concrete and the concrete manufacture should conform to AS 3600—2001.
5.5.2
CONCRETE ADDITIVES Admixtures or concrete materials containing calcium chloride or other chloride salts must not be used. Chemical admixtures including plasticisers may be used if they comply with AS 3600— 2001, Clause 19.
5.5.3
PREPARATION Before concrete is placed, remove any accumulated debris, grease or any other substance to ensure a clean bond with the BONDEK sheeting. Remove ponded rainwater. 38

CONSTRUCTION JOINTS It is accepted building practice to provide construction joints where a concrete pour is to be stopped. Such discontinuity may occur as a result of a planned or unplanned termination of a pour. A pour may be terminated at the end of a day’s work, because of bad weather or equipment failure. Where unplanned construction joints are made, the design engineer must approve the position. In certain applications, the addition of water stops may be required, such as in roof and balcony slabs where protection from corrosion of reinforcement and sheeting is necessary. Construction joints transverse to the span of the BONDEK sheeting are normally located where shear forces are a minimum (such as the midthird of a slab span) and ideally over a line of propping. Locate longitudinal construction joints in the pan (Figure 5.13). Form construction joints with a vertical face—the easiest technique is to sandwich a continuous reinforcement between two boards.
BONDEK
Longitudinal construction joint
Figure 5.13 Typical construction joints
5.5.5
Prior to recommencement of concreting, the construction joint must be prepared to receive the new concrete, and the preparation method will depend upon the age and condition of the old concrete. Generally, thorough cleaning is required to remove loose material, to roughen the surface and to expose the course aggregate.
PLACING The requirements for the handling and placing of the concrete are covered in AS 3600—2001, Clause 19.1.3 (Handling and placing of concrete). The concrete is placed between construction joints in a continuous operation so that new concrete is placed against plastic concrete to produce a monolithic mass. If the pouring has to be discontinued for any more than approximately one hour, depending on the temperature, a construction joint may be required.
During pouring, the concrete should be thoroughly compacted, worked around ribs and reinforcement, and into corners of the EDGE FORMS by using a vibrating compactor. Ensure that the reinforcement remains correctly positioned so that the specified minimum concrete cover is achieved. Unformed concrete surfaces are screeded and finished to achieve the specified surface texture, cover to reinforcement, depths, falls or other surface detailing. Surfaces which will be exposed, such as EDGE FORMS and exposed soffits, should be cleaned of concrete spills while still wet, to reduce subsequent work.
5.5.6
CURING After placement, the concrete is cured by conventional methods, for example, by keeping the slab moist for at least seven days, by covering the surface with sand, building paper or polythene sheeting immediately after it has been moistened with a fine spray of water. Follow AS 3600—2001, Clause 19.1.5 (Curing and protection of concrete) and good building practice. Be particularly careful when curing in very hot or very cold weather.
39
5 Construction
Start pouring close to one end and spread concrete uniformly, preferably over two or more spans. It is good practice to avoid excessive heaping of concrete and heavy load concentrations. When concrete is transported by wheel barrows, the use of planks or boards is recommended.
Until the concrete has cured, it is good practice to avoid concentrated loads such as barrows and passageways with heavy traffic.
5.5.7
WHEN TO REMOVE PROPS Various factors affect the earliest time when the props may be removed and a slab initially loaded. Methods of calculating times and other guides are given in AS 3610—1995, Clause 5.4.3 (Stage III of construction—Formwork stripping and after placement of concrete).
5.6 5.6.1
FINISHING SOFFIT AND EDGE FORM FINISHES For many applications, BONDEK gives an attractive appearance to the underside (or soffit) of a composite slab, and will provide a satisfactory ceiling—for example, in car parks, under-house storage and garages, industrial floors and the like. Similarly, EDGE FORM will give a suitable edging. Additional finishes take minimal extra effort. Where the BONDEK soffit is to be the ceiling, take care during construction to minimise propping marks (refer to Installation— Propping), and to provide a uniform surface at the side-laps (refer to INSTALLATION—FASTENING SIDE-LAP JOINTS). Exposed surfaces of BONDEK soffit and EDGE FORM may need cleaning and/or preparation for any following finishes. The cleaning preparations are shown in Table 5.2. Table 5.2 Preparation of soffits and Edge Form
Prepainted soffit or edge
Galvanised soffit or edge
• Remove all protective plastic strips from rolled corners. • Concrete seepage marks and dirt may be removed by washing with water. For stubborn stains, use a mild solution of pure soap or non-abrasive detergent in warm water. • Grease or oil deposits may be removed by washing as described above. For stubborn deposits contact us for advice. Never use abrasive or solvent type cleaners (like turps, petrol or kerosene) on pre-painted steel. • Light corrosion marks indicated by white to grey staining due to wet bundles may be removed with a kerosene rag. If this is unsatisfactory, then wire brushing may be necessary. Take care not to unnecessarily remove any of the zinc coating. If zinc coating is removed, a suitable paint system must be used. • Grease or oil deposits may be removed with a kerosene rag. For stubborn deposits, use paint thinners. • Concrete seepage marks and dirt to be removed by washing as described above.
5.6.2
PAINTING Various painting systems are available for use with zinc coatings to provide a decorative finish and/or to provide an appropriate corrosion protection system. There are recommendations suitable for painting soffits and edges in Painting zinc-coated or zincalume steel sheet (BLUESCOPE LYSAGHT technical information booklet). Field (on site) painting systems from that booklet are summarised in Table 5.3. The performance of a paint system is influenced by the quality of preparation and application—closely follow the paint manufacturer’s instructions. For painted soffits, it may be preferable to cover the gaps of the ribs prior to painting. BONSTRIP snaps into the gaps of the ribs of the BONDEK sheeting and produces an attractive appearance (Figure 5.14). The gap at the side-lap joint can be filled with a continuous bead of silicon sealant prior to painting. 40

PLASTERING Finishes such as vermiculite plaster can be applied directly to the underside of BONDEK with the open rib providing a positive key. With some products it may be necessary to treat the galvanised steel surface with an appropriate bonding agent prior to application. Plaster-based finishes can be trowelled smooth, or sprayed on to give a textured surface. They can also be coloured to suit interior design requirements.

5 Construction
Where a building is being refurbished, or there is a change of occupancy and floor use, you may need to increase the fire resistance of the BONDEK composite slabs. This may be achieved by the addition of a suitable fire-protection material to the underside of the slabs. The open ribs of BONDEK provide a positive key to keep the fire spray in position. Such work is beyond the scope of this manual.
5.7.2
SUSPENDED CEILING Ceilings are easily suspended from bondek slabs using Ceiling Suspension Nuts, BON-NUT suspension nuts, or BONWEDGE suspension brackets which comply with the load capacity requirements of AS 2785. Threaded rods or wire hangers are then used to support the ceiling. Alternatively, hangers may be attached to eyelet pins powder-driven into the underside of the slab, or to pigtail hangers inserted through pilot holes in the BONDEK sheeting before concreting (Figure 5.16).
5.7.3
SUSPENDED SERVICES Services such as fire sprinkler systems, piping and ducting are easily suspended from BONDEK slabs using BON-NUT suspension nuts which comply with the load capacity requirements of AS2118 (Figure5.16). Ceiling Suspension Nuts or BONWEDGE suspension brackets are suitable for services other than fire sprinkler systems—threaded rods being used to support the services.

The crack control for flexure is not required, consequently two options may be considered (see Section 3.2). The reduced weight of lightweight concrete may be ignored (see Section 3.5.4). The ratio of longer to shorter span length does not exceed 1.2, reinforcing bar is 10 mm diameter, thus all necessary data can be read directly from the design tables. Solution 1: Slab is designed as continuous for strength and serviceability The data in the tables are applicable to both end and interior spans. From the table on Page 104: D = 140 mm; 2 rows of propping; 480 mm2 of negative reinforcement laid to standard Pattern 1 (Figure 3.1). From the table on Page 105: additional fire (longitudinal) reinforcement of 360 mm2 must be placed as required for Fire Detail 2 (Figure 4.5). From Table 3.6, mesh SL62, laid on the top (Figure 1.1), may be used to control cracking due to temperature and shrinkage effects. Concrete cover is 20 mm. Solution 2: Slab is designed as a series of simply-supported slabs. From table on Page 68, Dcs = 170 mm; 2 rows of propping, no negative reinforcement is necessary. From the table on Page 69: additional fire (longitudinal) reinforcement of 510 mm2 must be placed as required for Fire Detail 2 (Figure 4.5)—the only option for simply-supported slabs. The mesh SL72, laid on the bottom, may be used to control cracking due to temperature and shrinkage effects. The choice between these two options may depend on which option is more economical. 43

base metal thickness = 0.6 mm
Fire design: not required Vertical flexibility of support beams is small enough to be ignored. The ratio of longer to shorter span length does not exceed 1.2, thus all necessary data may be read directly from the design tables. Support B From the table on Page 116: Dcs = 190 mm for the end span (A–B); 2 rows of propping; 890 mm2 of negative reinforcement with bar 10 mm diameter, grade D500N only. Span length must be 5.1 metres, so don’t consider length of interior span of 5.2 metres. If the soffit is to be exposed, it is desirable to use form ply strips, 300 mm wide, for props to avoid localised damage to the BONDEK. However, L-grade reinforcement was specified, thus the area of negative reinforcement must be increased for all support regions because moment redistribution is not allowed for L-grade reinforcement (Section 3.10): Ast– = 890 x 1.43 = 1273 mm2. Proper compacting and placing of concrete is possible (Section 3.8.3). The negative reinforcement pattern is a standard one (Figure 3.1). The RL818 mesh, placed on top, may be used to control temperature and shrinkage effects.
44
Support A The design of the top negative reinforcement (Figure 1.1) must be based on rotational restraint provided by the end band-beam (similar to the left side of Figure 3.1); and can be taken conservatively as for Support B. Supports D The span length is taken as 4.5 m (maximum of 4.4 m, and 4.5 m). Our design tables would give a thickness less than 190 mm. You may design the slab with that reduced thickness or keep 190 mm throughout. In both cases 820 mm2 of negative reinforcement is acceptable, though a bit conservative for 190 mm. A 160 mm option would require Pattern 2 of negative reinforcement (Figure 3.2). Ast– = 820 x 1.43 = 1173 mm2 Note that the first interior span (B-C) must always have the same thickness as the end span. Anchorage reinforcement: End support w/L = (2 x 0.5) / 5.1 = 0.2 (Table 3.8) Aanchorage = 0.23 x 890 = 205 mm2 (D500L or D500N) Anchorage reinforcement: Support B Aanchorage = 0.16 x 890 = 142 mm2 Anchorage reinforcement: Support D Aanchorage = 0.16 x 820 = 131 mm2 For fire-rated buildings, the bottom fire reinforcement can also be treated as anchorage reinforcement. To get a more economical design you could run BONDEK 2003, because our design tables were developed for steel-frame and masonry-wall construction and don’t allow for the positive effect of band-beams on deflections and propping. BONDEK 2003 is likely to give: a thinner slab;
•
less reinforcement for interior spans;
•
slabs for interior spans may be designed thinner than end spans;
•
less negative reinforcement required if D500N is specified for shrinkage reinforcement; and
•
less temporary props.

base metal thickness = 1.00 mm
Fire resistance period = F60 Our Design Tables are worked out for normal weight concrete with superimposed dead load not exceeding 1 kPa. The superimposed load in this example is 3 kPa and must be transformed into additional live load as described in Section 3.5.5. This can be done using the advantage of light-weight concrete: Additional Live load = (3 - 1 - (25 - 21) x 0.2) x 2 = 2.4 kPa (where Dcs = 200 mm - preliminary slab thickness from the table on Page 58). Total transformed live load = 5.4 kPa. From the table on Page 58: Dcs = 190 mm; 1 row of propping. From the table on Page 59: additional fire (longitudinal) reinforcement of 460 mm2 (≥10 mm diameter, D500N) must be placed as required for Fire Detail 2 (Figure 4.5)—the only option for simply-supported slabs. The mesh RL818, placed on the bottom, may be used to control shrinkage and temperature effects.

BONDEK 2003 SOFTWARE Our latest version – BONDEK 2003 software gives solutions that conform to AS 3600—2001 Concrete structures. The old version BONDEK 2000 was used to generate the design tables in this book. BONDEK 2003 should be used to get more economical solutions, than you may get from the tables, because it offers many additional design options (see below). Additional options • Design with interior spans thinner than end spans • Design of concrete-frame buildings with specified dimensions of band beams and refined deflection calculations (slab thickness thinner than given in the tables of Chapters 7 and 8) • All reinforcement grades and bar diameters, in any combination, for negative, fire and shrinkage reinforcement • An option of D500N grade for shrinkage reinforcement, which significantly reduces the amount of fire and negative reinforcement (eliminates any need for these reinforcements for short spans) • Specified number of continuous spans (two-span, three-span etc.) • Equal spans • Lightweight concrete • Superimposed dead load other than 1 kPa • Option which checks your chosen slab thickness and designs the rest of the parameters • 20 MPa live load • Fire rating of 4 hours • Storage live loads (ψs = 1, ψl = 0.6) • Design with no crack control requirements • Design of formwork as continuous or discontinuous over permanent supports • A2 exposure classification • Enhanced fire design What’s on the CD The CD contains: • The
BONDEK
2003 software;
• A help file for the application; and • The manual Using Bondek: Design and construction, in Adobe Acrobat (.pdf) format. Running the CD The BONDEK 2003 CD-ROM is fixed on the inside back cover of this book. To run BONDEK 2003 your computer must have Microsoft Excel 98, or a later version, on either Windows or Apple platforms. To read the manual you need Adobe Acrobat, an application available free from www.adobe.com. On your hard disk, create a directory (folder) called Bondek 2003, and place the files from the CD into the folder. Run the applications, in the usual way, by double-clicking on the icons. Run the help file by clicking on the help button on the bondek application. 120
