Abstract

The vulnerability of existing reinforced concrete building in India has been exposed to recent earthquakes. The Bhuj earthquake (2001) has caused significant damage to multi-story buildings in Gujarat's urban area. The many existing Indian RC buildings, mainly designed for gravity loads, were seriously threatened. Following the damage and collapse of numerous concrete structures during recent earthquakes, the need to assess seismic adequacy of existing structures became clear. A simplified assessment process is highly needed for a country such as India that is prone to earthquakes in order to carry out a seismic assessment. The response of buildings to earthquakes in terms of reservation of life and risk management is important to estimate. The Response Spectrum analysis procedure is used to evaluate the existing design of a bare black frame of reinforced concrete, infill frame, and infill frame and soil effect. The response spectrum analysis for the seismic assessment of existing buildings is performed in order to assess the performance of these models. The analysis reinforcement needed in each format is determined and retrofitted accordingly. In this study, a different retrofitting method is studied. In seismic evaluation of existing RC buildings, it is also concluded that the effect of infill plays a critical role
