Diaphragm shear stiffness
WebSep 1, 2016 · Diaphragm stiffness is a function of the in-plane stiffness of the corrugated panels, the stiffness of fasteners placed through the panels (both structural and sidelap) and the warping behavior of the corrugated panels. WebThe shear capacities of the diaphragm panels will automatically be multiplied by 1.4 for wind forces if the Wind ASIF function is enabled. Wood Diaphragm Design Rules Note that these are only available in a combined RISAFloor/RISA-3D model. Here you can input the parameters for your diaphragm design.

In their … 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 ...
