EVALUTING THE PERFORMANCE LEVEL OF RCC FRAME STRUCTURE BY PERFORMANCE BASED ANALYSIS USING SAP 2000

Abstract

In every part of the world earthquakes are very common. Geographical figures of India show that almost 54% of the land is at risk to earthquakes. A report by the World Bank & United Nations estimates that about 200 million city inhabitants in India will be exposed in few years to earthquake. Due to the earthquakes, excessive destruction of infrastructure and buildings can be caused. Increasingly, the non-linear analysis are a popular and relatively new and powerful way for seismic performance evaluation of new and existing building structures. Persistent hard work to resolve the variances between the actual observed performance and the expected performance of building structures is needed. It is expected that on the structural system and its components, the pushover analysis will provide sufficient data on seismic demands imposed by the design ground motion. The main objective of present study is to find the performance of building structure under earthquake using performance based seismic design analysis. Nonlinear (Pushover) static analysis is method to evaluate the performance level of building. In this report, pushover analysis is carried out for a 9 stories building situated in ZONE IV to check the seismicity effect and performance level of a building by SAP2000. Pushover Analysis produces a Pushover curve consists of capacity spectrum, demand spectrum and performance point.
