WebXu et al (Chengxiang et al. Citation 2024) carried out a seismic fragility analysis of steel-reinforced concrete frame structures with OpenSees software and investigated the differences in the seismic fragility curves based on the peak inter-storey drift ratio (IDR) and two damage indices, demonstrating that the analysis based on the damage ...
http://support.i-car.com/download/574 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 …
