Abstract:The static pushover analysis is becoming a popular tool for seismic performance evaluation of existing and new structures. The existing building can become seismically deficient since seismic design code requirements are constantly upgraded and advancement in engineering knowledge. Further, Indian buildingsn built over past two decades are seismically deficient because of lack of awareness regarding seismic behavior of structures. The widespread damage especially to RC buildings during earthquakes around the world generated agreat demand for developing a simple yet efficiently accurate new method known as “pushover analysis” for seismic evaluation. The expectation is that the “non-linear static analysis” popularly known as “pushover analysis” will provide adequate information on seismic demands imposed by the design ground motion on the structural system and its components and consumes very less time compared to non-linear dynamic analysis. In a real structure the strength of concrete and steel may not be the same as assumed in the analysis, it may be more or less, Since the output of the analysis is very much sensitive to design parameters, in the present thesis,attempt is made to understand the sensitivity of design parameters like strength of concrete, strength of steel andcover to reinforcement on performance of structures namely bare frame structure and frame with rigid slab and compare the variation in performance within these two.

Keywords:Non-linear static Pushover analysis, sensitivity of strength of concrete and steel, seismic evaluation
