The urban multi-storey buildings in India today have open ground storey primarily being adopted to accommodate parking, communication hall, reception lobbies or offices etc. Providing open ground storey in buildings reduce the stiffness of the lateral load resisting system. Many collapse of buildings observed during past earthquakes due to open ground storey. The present paper review on the seismic performance of soft storey of RC frame building using static and dynamic analysis. Analysis are carried out using various software like Etabs, Staad Pro and Sap2000. It is observed that, increasing the size of columns in an open ground storey to balance the stiffness is adopted. To strengthening the soft storey building the different techniques are provided i.e. shear walls, dampers and bracing which improve the seismic behaviour of the structure and also reduces the stiffness irregularity. Thus by improving lateral strength and stiffness, the maximum building resistant against collapse during earthquakes.
