Deflection Analysis

Shearwalls calculates the deflection of all wall segments between openings or wall ends for each design case (wind, seismic, rigid, flexible, E->W, W->E) in order to

• determine the storey drift, and check that it is within allowable limits, for both seismic and wind design
• distribute loads to segments within a shear line based on equal deflection of segments,
• determine rigidities for the rigid diaphragm method of distributing loads to shear walls.

Deflection analysis is performed by Shearwalls only if the Include deflection analysis setting in the Design Settings is checked.

The sources of deflection and calculation procedures are described under Deflection Equation and Components.
