Title: Evaluation Seismic Response for Soft Storey Building Retrofitted with Infill, Steel Bracing and Shear Wall
Abstract: Open ground construction is quite prevalent from last 25 years in metropolitan India. Buildings with open ground stories are to be particularly exposed to collapse, and severe damage under earthquake excitation. Although, many buildings constructed in recent times have been observed adverse effect during Bhuj earthquake. The study has been performed to work out the performance of RC building with open ground storey subjected to seismic loads. In present work, twelve storied building are taken into account and the performance of structure evaluated by using pushover analysis in SAP 2000 software. The analytical results discussed in the nature of capacity curve, structure performance point and plastic hinge development pattern. Result indicated that, there are formations of plastic hinges at ground storey column level. To counteract the total collapse of soft storey structures, there is need to retrofit the open storey. Therefore, the alternative measures are recommended to get better the reaction of soft storey like RC shear wall, steel bracing, and infill wall.
