Diaphragm shear calculation

WebDec 11, 2013 · Background. The NDS and IBC etc. provide an equation for a simple span diaphragm spanning between two resisting shear walls. The formula takes into account flexural type bending and shear deformation in the diaphragm, nail slip, etc. However, for a three-sided building with an open front (i.e. two side and one rear shearwall) the … WebDec 17, 2024 · Should the shear wall force be obtained by simply multiplying the cantilever width with the diaphragm force, or should it be analyzed like a true cantilever beam, the shear wall force being equal to the reaction at the beam support? The selection of analysis begins to unravel for me when the results can vary so significantly.
