Abstract

A systematic seismic vulnerability assessment of a benchmark 8-story structure representing pre-seismic code frame buildings in a highly populated and seismically active area is conducted in this study. Detailed structural design and fiber-based modeling are carried out for the reference structure. Forty earthquake records are selected to represent potential earthquake scenarios in the study area. Al large number of inelastic pushover analyses (IPAs) and incremental dynamic analyses (IDAs) are performed to select the performance criteria and to derive fragility relationships for the reference building. It is concluded that this category of pre-code structures is substantially vulnerable to seismic loads. The derived fragility curves for the retrofitted reference structure using Buckling Restrained Braces (BRBs) proved that such technique is efficient in reducing the seismic losses of pre-code frame structures and increasing public safety. Keywords: vulnerability assessment, pre-code RC frames, seismic retrofit, inelastic dynamic simulations, BRB.
