Abstract
The impact of recent earthquakes on concrete structures, in which many buildings suffered significant damage or collapsed, has highlighted the need to assess the seismic adequacy of existing structures. In particular, the seismic rehabilitation of older concrete structures in high seismicity areas is a matter of growing concern, since structures susceptible to damage must be identified and an acceptable level of safety must be determined.Reinforced concrete structures designed according to the Egyptian seismic code are expected to undergo excursions in the nonlinear range. Such behavior cannot be predicted by conventional seismic analysis methods. Thus, an alternative approach called "pushover analysis" can be used. In this study, a pushover analysis of a reinforced concrete frames designed according to the Egyptian code is carried out. The results obtained suggest that pushover analysis is attractive and can help the structural engineer better understand the behavior of a structure for the design of new structures and also for the rehabilitation and retrofit of existing structures.
