Abstract
The seismic evaluation of existing buildings is a more troublesome assignment than the seismic design of new buildings. The need for seismic evaluation for buildings becomes necessary to know the level of structural damage and how to cure it due to earthquakes. The seismic evaluation shows how the structure’s behavior under seismic loads and determines the ultimate capacity for the structure, there are several methods used in seismic assessment in the analysis which may be static or dynamic. In this study, an educational building located in Egypt has been evaluated for the seismic load to decide if there is a need for retrofitting or not. The seismostruct program is used for modeling and analyzing three dimensional reinforced concrete (RC) buildings with different stories; Ground +4 stories (G+4), Ground +7 stories (G+7), Ground +10 stories (G+10), and Ground +13 stories (G+13) RC building located in different seismic zones; II, III, IV, and zone V. A nonlinear static pushover analysis (POA) using the displacement coefficient method was used to evaluate the seismic performance of the existing building. The analysis results are disseminated in terms of inter-story drift ratio, capacity curves with performance point, and performance criteria checks for each model.
