Seismic vulnerability assessment of mid-rise reinforced concrete building in Ahmedabad

Abstract

The city of Ahmedabad is one of the most urbanized and crowded cities in the western part of India. The vulnerability associated with this city has increased due to haphazard development, owing to rapid urbanization and industrial development. This article focuses on evaluating the performance of an existing mid-rise RC frame building in a densely populated area of the city. The selected stock building is precisely modeled in SAP2000 for carrying out its pushover analysis from which the capacity spectrum is obtained as per the recommendations of ATC-40. Finally, the Fragility curve is produced as per the guidelines of HAZUS and the damageability function of the building is calculated. From the results of fragility curve and damage probability function, it is deduced that the building will suffer extensive damage during a seismic event.
