NON-LINEAR STATIC PUSHOVER ANALYSIS OF RC FRAME BUILDINGS

Abstract

The existing building can become seismically deficient since seismic design code requirements are constantly upgraded and advancement in engineering knowledge. Further, Indian buildings built over past two decades are seismically deficient because of lack of awareness regarding seismic behaviour of structures. Of the several assessment methods, Response spectrum and pushover analysis procedures have been widely used for seismic evaluation. In this project the theoretical background of these methods is studied in brief and above methods are applied to assess the seismic performance of five storied reinforced concrete buildings. The buildings taken for study are located in Zone V. The analysis was performed using SAP 2000 software. In the response spectrum analysis first the building is designed for gravity and earthquake loadings taking into consideration different (I/R) ratios. In pushover analysis the sequence of hinge formation and performance point were observed and their significance on the performance of the building have been discussed
