Diaphragm shear calculation
WebThe diaphragm shear transfer calculations on calc page 350 do not appear to include rho in the calculation. For example, at Story 3 Pier CA, page 302 indicates that rho_Vn_max = 520 kips, however V=380 kips per page 350. Please clarify how the forces on Page 350 are determined. Furthermore, please clarify why the pier forces starting on 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. parkway chevrolet sherman txWebAn air operated double diaphragm pump is a pneumatic pump that uses an air valve that directs compressed air between two sides of the pump, back and forth.
