Important Note – These are descriptions to changes implemented in WoodWorks Shearwalls for version 10.0 and may not reflect current behavior
When you selected low rise wind loads, the seismic rigid diaphragm torsions were set to zero in the rigid diaphragm distribution method, so there was no additional torsional component to seismic shearline forces for rigid diaphragms, and the direct forces only were used. When the all heights wind load procedure was selected, the seismic torsions were correct. This has been corrected and seismic rigid diaphragm torsions are always calculated.
