Abstract: Soft first storey is a typical feature in the modern multi-storey constructions in urban India. Social and functional need to provide parking space at ground level leads seismic vulnerability of such a building. The computer software usage in civil engineering has greatly reduced the complexities of different aspects in the analysis and design of projects. In the present study an attempt has been made to investigate the seismic behaviour of a multi-storey building with soft first storey. When subjected to seismic loads, it was observed that soft storey frames are less resistant when compared to infill frames
