Seismic Vulnerability Assessment of Open Ground Storey Buildings
Abstract Open Ground Storey (OGS) in multistoried buildings is meant for a parking space within a building plan. These buildings have reduced stiffness at the ground storey due to absence of in-fill walls. The abrupt change in the stiffness of the open ground storey compared to the stories at the top result in huge seismic displacement demand, to be borne by the ground storey itself. Conflict demand between seismic safety and functional requirement, and moreover huge number of OGS buildings in urban areas in India, necessitates the seismic vulnerability assessment of OGS buildings. In the present paper, a simplified procedure to assess the level of severity of OGS building is developed using plastic hinge concept. The simplified procedure is validated with the shake table experiment conducted on three-storey model OGS building. The simplified procedure will help to identify the urgency for repair and rehabilitation of OGS buildings.
