Soft Storey and Retrofit of Existing Multi Storeyed Buildings in India: A Critical Review

Nakul Singh, Vikram Singh Kashyap, Rishikesh kumar


Soft first storey is a typical feature in the modern multi-storey constructions in urban India.  Though multi-storeyed buildings with soft storey floor are inherently vulnerable to collapse due to earthquake, their construction is still widespread in the developing like India. Functional and Social need to provide car parking space at ground level and for offices open stories at different level of structure far out-weighs the warning against such buildings from engineering community. With the availability of fast computers, so that software usage in civil engineering has greatly reduced the complexities of different aspects in the analysis and design of projects.  In this paper an investigation has been made to study about soft storey building with different arrangement in soft storey building when subjected to static and dynamic earthquake loading and retrofit strategies of existing multi storeyed building in Indian scenario and is observed that, providing infill wall improves resistant behaviour of the structure when compared to soft storey provided.
