Seismic Behavior of RC Framed Building with Soft Storey

Abstract

Open ground storey system is being adopted in many buildings presently due to the advantage of open space to meet the economical and architectural demands. For offices or for any other purpose such as communication hall etc. soft storey at different levels of structure is constructed. Hence in this study an attempt has been made to investigate performance of a building with soft storey (G+14) at different level along with ground level. Also it has been tried to investigate on adding of shear wall to structures in order to reduce soft storey effect on seismic response of building. The linear response spectrum analysis was carried out and the results obtained from models were compared in terms of storey displacement, storey drift, storey shear, time period and best alternative for construction in earthquake-prone area was selected.
