Since the center of mass does not coincide with the center of rigidity, the seismic shear force causes torsion.
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
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?
