6. Bug where the column reduction factor was not updated in the analysis and causing the column to fail in the analysis is now fixed. (fixed in version 7.6.71. C Net 2.0 onwards). Meaning, unbraced slender columns which failed previously in analysis will now pass because it is now able to update the reduction factor used in reducing the moment in the analysis.

Previously, the end bars were not anchored into the columns.

3. Beam detailing. Tension lap will be used when there is a sagging moment at the support. The 2D Full Moment will be used to decide whether tension or compression lap is used. For more details, go to Technical Documentation > Beam > Detailing > "Use tension bar lapping for sagging moment at support".

48. The loading shown on pad footing detailing is the equivalent design service load, (equivalent column load + pad footing self-weight). Please refer to User Manual > Main Menu > Design Results > Pad Footing > Detailing for detailed explanation.

7.5.84.0 C .Net 2 (11 May 2009)

1.

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. Batch run 2D and 3D analysis with wall design. Click "Design Report > Wall" and check on the summary report.

The wall would fail in design.

If you create the same model and repeat the same steps mentioned above in version lower than 7.5.44.0 you will find that the wall will pass in design.

_Warning

_:

Any version before 7.5.7.0 does not take into consideration the 3D Analysis results for the shear/torsion design of beams. Critical it will cause under design in shear/torsion of transfer wall partially sitting on transfer beam as the design of this beam requires the 3D results which is not taken into account.

(60)

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"

(61)

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 ratio of wall design is now checked against "Limits of Slenderness" (version_7.5.89.0). 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 &

Reminder

:

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

(62)

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.
