Abstract


In this research, an assessment of seismic performance of multi-story reinforced concrete structures in Egypt is performed. Five structural models designed according to the Egyptian code of loads and practice are se-lected to investigate their seismic response under twelve ground motions using SeismoStruct software. In order to understand the overall response of selected structures natural periods and mode shapes are obtained from eigenvalue analysis using SeismoStruct software. Horizontal capacity of the selected structures is esti-mated through nonlinear static pushover analysis using SeismoStruct software, where the models subjected to static triangular load distributions at each floor. Incremental dynamic analysis curves are presented for each structural model. In this research, four damage limits are considered; fully operational (FO), operational (OP), life safe (LS), and near collapse (NC) damage limit, these limits are defined according to the interstory drift ratio with values of maximum permissible interstory drift ratio according to SEAOC vision 2000
