Wood-Armer overview
OVERVIEW
Wood-Armer is a post-processor to the SuperSTRESS frame analysis package and is used to aid the design of a reinforced concrete slab idealised as a grid frame or space frame. The program will only operate with the SuperSTRESS grid frame and space frame modules. The program is based on one originally developed by Babtie Shaw and Morton (now Babtie Group). This was given DTP approval number MOT/EBP/268C. To use Wood-Armer, you should be fully familiar with SuperSTRESS frame analysis, the program environment utilities and the input and output methods of SuperSTRESS. Wood-Armer uses the SuperSTRESS analysis results to determine the reinforcement moments in the top and bottom of the slab according to the basic Wood and Armer equations. The method is strictly applicable to solid slabs, but it is generally accepted that it can be used with slabs that are voided if the voiding is not significant and the top and bottom surfaces of the slab are continuous. These surfaces need to be continuous since it is assumed that they provide the means by which torsion is redistributed. (See references 3 and 4 for more information on the applicability of this method.) The following topic describes the method of running Wood-Armer from the SuperSTRESS Explorer and Main menu bar.
1.2
Wood-Armer running
Wood-Armer should be seen as a SuperSTRESS Tool, similar to SS-SURF. If you have analysis results for a grid frame or space frame, you can access WoodArmer from the Explorer or the tools menu on the main menu bar within SuperSTRESS. Explorer

You must be familiar with the methods of arranging the geometric layouts of grillage beams to simulate the behaviour of slab and pseudo-slab decks, and also the methods of calculating and apportioning the structural parameters required for the analysis. These techniques will be necessary when modelling the slab in SuperSTRESS. See grillage idealisation and references for more information. It is assumed that you have specified the required loading patterns prior to the SuperSTRESS analysis.
1.4
Wood-Armer limitations
The axis of the main reinforcement and the longitudinal members of the grid frame must be aligned with the g lobal X-axis of the structure. The program is essentially only intended for regular meshes, either orthogonal or skew. The internal, as opposed to the peripheral nodes, will generally have four members framing into them, which the program recognises as two pairs of opposing members. The program can cope with an additional pair of members at each node. These are referred to as unaligned members, since they are not aligned with the main axes of the deck. Typically these occur at the transverse edges of the deck. All pairs of members must be collinear and on opposite sides of the node. This is also true for peripheral nodes, except that here one half of a pair of members may not be present. See Member Width Table for a further explanation of aligned and unaligned members.

Wood-Armer sign convention
OVERVIEW
Refer to the SuperSTRESS sign convention for information on the grillage moment conventions. The sign convention for the reported global slab moments is as shown below, and is the same as that used by Wood.
The Reinforcement Skew Angle A is the angle from the global X axis to the transverse reinforcement. It is positive when clockwise in plan. Note the difference between the slab moments, where Mx is a moment in the global X direction, ie about the global Y axis, and SuperSTRESS , where MX is a moment about the global X axis. The sign convention for the Wood-Armer moments is that the top steel design moments are always given as negative values and the bottom ones as positive.

Wood-Armer units
This release of Wood-Armer uses fixed units for input and output. These are: Dimensions: m Angles: degrees Moments: kNm/m

Wood-Armer data
2.1
Reinforcement skew angle
DATA
The reinforcement skew angle dialog will appear if reinforcement angle is selected from the Explorer or Tools menu. The major steel runs parallel to the global structure X-axis (see sign conventions) and also the longitudinal members. The angle between the major steel and the minor steel is defined as the reinforcement skew angle and this angle is considered positive when measured in a clockwise direction when viewed in plan. The angle must be in the range -90° to -10°, +10° to +90°. The entry will be checked to make sure that the reinforcement angle has been set to an appropriate value. If this check fails the message box below will be displayed.
2.2
Member width and alignment table
All entries in the table default to a member width of one metre and 'aligned'. It is your responsibility to enter appropriate values for the current job. The table may be filtered by Structure Set so only those members that have valid member width properties need be included. To filter right-click in the table. The table behaviour is just as other SuperSTRESS input tables. The table will be updated automatically if any changes are made to SuperSTRESS data, such as joint or member editing. Page

Wood-Armer
DATA
Copy and block fill are enabled in the table. Width
The forces obtained from the analysis relate to the members used to model the slab as a grid frame. Those forces therefore represent the forces carried by a width of the slab modelled by each member. To derive the force per unit width of slab for the Wood-Armer calculations you must specify the width of slab carried by each member. The default width is 1m. The width is checked to ensure that it is in the range 1mm < width < 100m, and that it contains only valid numbers. The following error pop-up will be displayed if errors are found.
If invalid data is imported into the table, the cells will be coloured red with yellow text. Member alignment
Members must be specified as being aligned or unaligned. This is a drop-down list and no alternatives are available. Aligned members are those that are parallel to the majority of members, in either the longitudinal or transverse directions. There may only be a maximum of four aligned members at any node. Unaligned should usually only be specified for members on the edge of the slab which run at a different angle to the internal transverse members. This will typically occur in a skew slab when the transverse members are perpendicular to the Page

Wood-Armer
DATA
longitudinal members. However, unaligned members may be used internally, as in the diagram above, but there may only be a maximum of two at any node. The table may be filtered by opening the properties dialog for the table (right-click on the table), or from the main menu bar View / Properties.
The structure set facility enables you to filter by any existing set, including ALL and CURRENT. The check box must be ticked for the filter to have effect. The Member List facility enables you to filter by member list – see List Input. The default is ALL. The check box must be ticked for the filter to have effect. On closing the dialog, the set and list are checked and appropriate error messages displayed if necessary. To be in the table, a member must occur in both the structure set and the member list.
2.3
Calculation set
The calculation set dialog above will be shown when calculation set is selected from the Explorer or Tools menu. You may select ALL (the default), CURRENT, or one of the previously defined SuperSTRESS structure sets. A calculation set is a SuperSTRESS structure set on which the Wood-Armer calculations will be made. It may be part of a grillage or space frame, and, on closing the dialog, the following criteria are checked to make sure the members in the set comply with basic program assumptions and limitations. If any of these checks identifies errors, the calculation will not proceed. All members/joints within a structure set will be checked for errors irrespective of whether a previous member has failed. All joints in X, This will check that the Z co-ordinate is the same for all joints within Y Plane the calculation set. Joints will be compared to the first one in the structure set.

structure set but are attached to joints that are within the structure set will also be checked. If any such members are found not to be in the X-Y plane, these members will be ignored within the calculation but you will be warned with the following message. 'Moments from members connected to the calculation set but which are not in the same X-Y plane have been ignored within the calculation'. If members (whether in the set or not) attached to joints in the calculation set are within the X-Y plane the fixed end moments for the appropriate end of the member will be taken into account within the Wood-Armer calculations. The tolerance is 0.0001m. f this check fails the following message will be displayed. 'The calculation set must all be in the same X-Y plane'. Longitudinal All members that are within the structure set that are set to Aligned Criteria and are parallel with the X-axis will be assumed to be the longitudinal members of the grillage. The members will be checked to make sure they are parallel with the X-axis. The tolerance is 0.01°. If this check fails the following message will be displayed.
'There is an error in the geometry of the grillage. Please review the Help file for more information on resolving grillage geometrical errors'. Transverse Criteria
This will check that all members which are not parallel to the X axis and have been set to Aligned by the user are parallel with each other. See the deck layout diagram above. Members will be compared to the first one in the structure set that has been set to Aligned and is not parallel with the X-axis and all errors will be listed based on this comparison. The tolerance is 0.01°. If this check fails the following message will be displayed. 'There is an error in the geometry of the grillage. Please review the Help file for more information on resolving grillage geometrical errors'.
Aligned Criteria
This will check that there are a maximum of four Aligned members at any one node, as shown in the deck layout diagram below. If this check fails the following message will be displayed. 'There is an error in the geometry of the grillage. Please review the Help file for more information on resolving grillage geometrical errors'.
Unaligned Criteria
This will involve checking that there are a maximum of two Unaligned members at any one node and that pairs of Unaligned members framing into a node are collinear, as shown in the deck layout diagram below. If this check fails the following message will be displayed. 'There is an error in the geometry of the grillage. Please review the Page 10

In addition to the above checks, the calculation set is rechecked to make sure it has not been deleted, and the reinforcement angle is rechecked. Within the calculation the chosen structure set will be considered in the following way. •
•
All selected joints within a structure set will be included in calculation output. The results will be based on the end moments of all members that frame into the included joints whether part of the structure set or not.

Wood-Armer calculations overview
CALCULATIONS
The Wood and Armer moments can be calculated for any basic, pattern or combination loadcase analysed by SuperSTRESS. You may select or deselect each loadcase and combination from properties in the output table. The calculation procedure is automatic when the table is opened or filtered. For each of the selected loadcases and combinations, Wood-Armer calculates the following: •
The moment triads at the member ends for each node of the grid frame. This is the resolution of the moments at the ends of each member coming into a joint with respect to the global X and Y axes.
•
•
3.2
Wood-Armer theory
The global slab moments. The resolved triad moments for a pair of members at a particular node are averaged across the node in accordance with Wood and Armer theory. The global slab moments MX, MY, MXY are then aggregated from these averaged values. Finally the Wood and Armer moments are calculated for the slab. These are the moments of resistance required to be generated by the top and bottom reinforced concrete sections in the longitudinal and transverse directions.
The Wood and Armer method calculates the moment of resistance required by reinforcement placed in two directions in a slab. The steel may be either at the top, bottom, or both. This means that up to four values of reinforcement moment can occur at any point. The moments in the direction of the reinforcement are defined as M*x and M*y. Generally M*x is considered the major steel moment and M*y the minor steel moment. The Wood and Armer moments at a point in the slab are derived from the global slab moments at that point. The method assumes that the global slab moments, the moments about two orthogonal axes plus the torsion, are in equilibrium with the applied loading at the point. The moments and torsions in each member framing into a joint are averaged to give the global slab moments. These are then available for output after the calculation of the moments has been completed.
3.3
Grillage idealisation
The Wood-Armer method assumes that the members of the grillage under consideration represent an idealisation of a two-way slab. The slab should be divided into strips of uniform width, and each strip idealised by a SuperSTRESS member of the correct stiffness placed along the central axis of the strip. Suppose such a strip has width w and depth d. The properties of the SuperSTRESS member should then be: Iy = wd3 12
Page 12
Wood-Armer
CALCULATIONS
Ix = wd3 6 Note that the torsional stiffness Ix is half what would be expected for that of a thin beam of the same dimensions. This is explained in Hambly (see references). If edge members represent narrower widths of slab than internal members, the stiffnesses should be reduced correspondingly.
3.4
Global slab moments calculation
U, V
local member axes (V = SuperSTRESS member x axis, U = y axis)
α

Moments are positive clockwise looking in the p ositive axis direction The calculation of the global slab moments MX, MY, MXY at each node in the selected structure set is carried out in three stages. 1.
The end moments and torques of each member framing into the node are resolved into component forces in both the X and Y directions. This is clearly only necessary for members which are not aligned with either the X or Y global axes. The method of transformation of the forces is as follows. a.
The slab moments per unit width are calculated from the SuperSTRESS moments.

CALCULATIONS
Where Mx and My are the SuperSTRESS member end moments and W is the width of slab represented by the member (from the member width table). b.
The slab moments are now expressed with respect to the global axes.
and
c.
So far, the method of transformation is similar to that outlined by West (see references), but Babtie took the process a step further by apportioning the resolved moments to both axes with regard to the skew angle of the member. By transforming the moments to both axes, they would be counted twice, so the components are reduced by sinα and cosα. The method is a conservative one in that algebraically the sum of the resolved moments is greater than the initial moments, but the transformation is likely to be more appropriate given a range of skew angles.
and
3.5
Wood-Armer moments calculation
2.
The forces derived in 1. above are calculated for each pair of members at a node and then averaged. The sum of the forces so calculated for each pair of members is then aggregated at the node to produce two pairs of forces
3.
The global slab moments at the node are then calculated as follows.
The calculation of the Wood-Armer moments for the top and bottom steel is based on formulae originally proposed by Dr R H Wood and subsequently amplified by G S T Armer (see references).
Page 14
Wood-Armer
CALCULATIONS
The program has been written to accommodate any combination of positive and negative values of the moment triad elements and the skewing of the transverse steel to an angle other than 90 degrees. The method used is as follows. Assume global slab moments MX, MY, MXY and a skew reinforcement angle A, where A is considered to be negative when measured anticlockwise with respect to the longitudinal steel or global X axis. Bottom steel design moments
By convention these moments are always positive.
The above formulae 1. and 2. are only applicable if the results prove to be positive. If either is negative, then alternative formulae are used as described below.
Top steel design moments
By convention, these moments are always negative.
The above formulae 7. and 8. are only applicable if the results prove to be negative. If either is positive, then alternative formulae are used as described below.

OUTPUT
The output options in Wood-Armer provide very selective printout of individual loadcases and loadcase envelopes to either the screen or printer. The screen output options are covered in Global slab moments output table and Wood-Ar mer moments output table. The printer output options are covered in Reports . All types of output have options to select the loadcases for output and to filter the output in various ways. These are explained in the following topics.
4.2
Wood-Armer output reports
The output in Wood-Armer is produced from the Reports option from Results on the main menu bar, or by double-clicking on Reports in the Explorer.
Wood-Armer Reports are additional sets of output to add to the standard SuperSUITE Reports. The general operation of Reports is described in SuperSTRESS Reports to which you should refer. This topic describes only the additional Sections provided by Wood-Armer. To access the Wood-Armer Sections from the New Section di alog, pick Wood-Armer from the mode selector at the top of the dialog. You may also add Sections from different modules to the same Report. In the Reports dialog, SuperSTRESS Sections are prefixed with 'SS:', Wood-Armer with 'WA:', and so on.
