Important Note – These are descriptions to changes implemented in WoodWorks Shearwalls for version 10.31 and may not reflect current behavior.
Released October 7, 2014 with Design Office 10, Service Release 3a
Starting with version 10.2, when manually input rigidities are selected as the rigidity method in the Design settings, the program re-set all relative rigidities to one when distributing loads.
Since load distribution is done before design, it was no longer possible to set manual rigidities that are then used in design, and the manual option was identical to the "equal rigidities" option. This has been corrected and the program again allows you to manually set the rigidity to be used for each wall in the structure.
If you change the manually input relative rigidity for one wall in a standard wall group, the program no longer applies it to all walls in that group, nor does it present a message box warning you of this. Instead, different walls within different groups can have different relative rigidities.
Note that the program did not apply the relative rigidity to all walls within a line walls in a line. The behaviour for design groups is now consistent with that approach. Rigidity usually depends on the geometry of the wall so it cannot be specified for all walls within a group or line containing walls of differing lengths.
The program still includes relative rigidity amongst those parameters in a Standard wall that can be used to create the initial values for a set of walls. However, it no longer includes rigidity among those parameters that define a standard wall when identifying what standard wall a physical wall pertains to.
