The diaphragm between the walls in a shear line would essentially remain rigid, and just bend between the shear lines themselves. Still, we agree that our initial design was a little liberal in what could be considered the same ... WebDDM03 presents diaphragm shear strength and stiffness equations for various steel deck profiles and commonly used attachment types (welds, power-actuated fasteners, or screws).

Webdiaphragms impractical in regions of high seismicity. This factor was derived from a parametric study completed during the DSDM research. This is having a large impact on ... calculated if the shear stiffness or slip stress of bearing pads is known. Consideration of anchorage where welded reinforcement is used together with headed anchor studs Web2. AISI S310/DDM Calculations for Shear Stiffness Corrugations in the diaphragm cause reductions in the in-plane shear stiffness below that of an equivalent flat plate, and the estimate for the reduced shear stiffness is essential for design. The deformations in a shear loaded diaphragm are assumed to be composed of deformations from pure
