Diaphragm shear calculation
WebT = Ve = seismic shear times eccentricity = torsion applied to the diaphragm, when V is due to a seismic shear acting in the y direction it is called V y and a separate loading case V … WebFigure 2: Eccentric Shear Replaced With Statically Equivalent, T and V y: (a) Torsion About C.R., (b) Direct Shear Acting Through C.R. 7 Torsional Shears The seismic shear force, V, acts through the center of mass (see Figure 1). Since the center of mass does not coincide with the center of rigidity, the seismic shear force causes torsion.
