WebA simplified pushover method for rapidly assessing the seismic capacity of shear-type frames is presented. The frame global force-displacement capacity is described as a trilinear curve passing through three limit states (LS): Damage LS (DLS), Life safety LS (LLS), and Collapse LS (CLS). The global LSs are obtained consequently to the … WebTo investigate the damage response of steel members and frames subjected to large-strain and low-period cyclic loading, a damage initiation criterion of structural steel is …
