Warning

: Bug in the calculation ofK (reduction factor that corrects the deflection to allow for the influence of axial load) fixed for wall design. The bug is more prominent in cases of longer slender wall as additional slenderness moment is a function of K and h (height of wall). The incorrect calculation ofK will result in a lower slenderness moment hence rendering the wall to be under design. This bug was fixed in version 7.5.44.0 onwards. You can study the example "Slender wall design-7.5.42.0-2503091201.zip" provided in the installation CD under sub-folder "\Projects " for clarity. Open the project.

You can study the example "Partial transfer wall-7.0.362.0-0705091447.zip" provided in the installation CD under sub-folder "\Projects " for clarity. Open the project. Batch run 2D and 3D analysis with beam design. Observe the shear force from the "Plan Loading and Result Diagram" 2D sh ear f or ce di agr am o n b eam g b1

3D sh ear f or ce d iagr am o n b eam g b1

Open the beam design full report and check the shear & torsion design calculation.

SHEAR & TORSION DESIGN CALCULATION LOCATION : SECTION 1 LEFT SUPPORT (B:0 mm E:1500 mm from le ft grid of spa n) Maximum Torsion within Zone, T = 19.6 kNm Shear at Location of Maximum Torsion, V = 251.8 kN

p60


The design shear of 251.8 kN is taken correctly from the 3D analysis results. If you run the same model with a version lower than7.5.7.0 you will discover that the 2D analysis results will be chosen hence the bug! When the wall sits across the whole length of the beam between the column, the strut and tie method would be employed to design the beam hence beam is deemed safe. In cases of transfer columns the accumulation of loading from all upper floor 2D analysis are generally more conservative than the 3D analysis results. User are advice to check and satisfy themselves with the design results. This bug has been fixed from version7.5.7.0 onwards.

3. Slenderness 7.5.89.0). ratio of wall design is now checked against "Limits of Slenderness" (version 4. Beam mark using grid info as mark previously not shown in design report is fixed. 5. Column On Beam(COB) must now be fully supported to integrity chec k.(Figure 2 & Figure 3 )

Figure 1 : The error message will warn user regarding the COB is not fully supported

The COB is Not Fully Supported

Reminder

: To avoid multi-grids at intersection as in example in the model below, user gird trimming.

p61


This is to avoid the element locking into different nodes, to prevent inaccurate meshing. User can trim grid lines to such an extent that it does not produce unnecessary grid nodes (generated at intersection of grid lines) using trim gridline

.

7. Continuous column (not from lowest floor) going down to foundation support condition now strictly follows the 3D column support parameter. 8. Wall restraint information window pops up at the right click command of a wall selected. 9. Beam mark parameter "Show Dimension" default set to TRUE. 10.
