EVALUATION OF THE SEISMIC ANALYSIS AND PERFORMANCE OF BUILDING IN ZONE III AND ZONE V

Abstract

Reinforced Concrete buildings are very popular practice in today’s context. The Reinforced concrete buildings in India are designed considering the IS 875 and IS 1983:2016 code guidelines. In this research, the seismic performance of reinforced concrete RC frame has been studied using linear and nonlinear analysis. The seven-story building has been modelled according to Indian standard code with the help of Finite Element Software ETABS v21.0.0. The response of the buildings in terms of Base shear, story displacement was studied for both building in zone III and V. The capacity of building is evaluated using displacement controlled nonlinear static analysis (Pushover). The time history load is applied to the structure to determine the seismic demand of the building at different PGA levels. The hazard levels have been quantified by plotting fragility curve for both Zone III and Zone V. For different damage state, the capacity and demand value are used to obtain the probability of exceeding at different PGA levels. The fragility curve is developed using First Order Second Order Method (FOSM). From the study, it is found, the buildings of Zone V are more vulnerable than compared to buildings of Zone III.
