Seismic risks of rc structures in india an analytical study

In the present scenario building with open ground story has become an unavoidable due to the parking demands in most of all cities. Though many works have concluded that open ground storey buildings are vulnerable to earthquakes, still these kinds of buildings are constructed till date across much part of cities falling under lower zones without considering earthquake loadings. In this present study an attempt is made to know the capacity of the column sections (200x450mm and 300x300mm) which are used in the present construction sites of low-raised buildings to sustain the earth quake loads which may occur in future and this study is based on the column P M M capacity and analysis is done based on the equivalent static analysis without considering infill effects. This study is taken to know the risk of earth quake in lower zones and to create awareness about seismic risk which has to be considered for selecting section of columns.
