Abstract :
In this paper seismic capacity of structure to resist earthquake force was estimated by the capacity spectrum method. To evaluate the performance of frame building under future expected earthquakes, non linear static pushover analysis was conducted following ATC 40 guidelines. A 2D Reinforced Concrete frame was modeled in SAP 2000 by incorporating plastic hinges at the end of the structural element. Capacity of the structure was obtained from pushover analysis. BNBC 1993 response spectrum was converted into ADRS format. Performance point of the structure was achieved from the intersection between capacity curve and ADRS spectrum.
