Deflection Analysis

Shearwalls now calculates the deflection of each wall segment between openings for each design case (wind, seismic, rigid, flexible, E->W, W->E) according to CSA O86 9.7. It uses this deflection to

• determine the storey drift, and check that it is within allowable limits
• distribute loads to segments within a shearline based on equal deflection of segments
• determine rigidities for the rigid diaphragm method of distributing loads to shearwalls

As deflection analysis can be costly in terms of processing time, this feature is optional. It is controlled by a checkbox in the design settings.
