Abstract – Recent earthquakes in which many concrete structures have been severely damaged or collapsed, have indicated the need for evaluating the seismic adequacy of existing buildings. About 60% of the land area of our country is susceptible to damaging levels of seismic hazard. One of the procedures is the nonlinear static pushover analysis which is becoming a popular tool for seismic performance evaluation of existing and new structures. By conducting this pushover analysis, we can know the weak zones in the structure and then we will decide whether the particular part is to be retrofitted or rehabilitated according to the requirement. In the present study the push over analysis is performed on RC building frames by changing the footing, infill wall, aspect ratio and introduction of bracings on the SAP2000 (version 14). These four features have the capacity to increase the seismic performance of the building and the bracings can be used for retrofitting for buildings which are structurally weak.
