Webwalls; this is similar to that described by Clough. The frame will primarily deform in shear mode when subjected to lateral forces and the wall will deform in a bending mode, see Figure 1. The connection of the frames and walls to a diaphragm requires deformation compatibility to exist for the entire structure. This compatibility restraint ... WebJun 6, 2011 · All shear forces for a steel diaphragm with no sidelaps must be transferred through the joist fasteners, usually puddle welds. Also with no sidelaps, you obviously are going to have more deflection/diaph. movement, because of the lesser stiffness of the entire system like JAE said.
