Abstract: In the present scenario, Conventional slab buildings are commonly used for construction. The use of Flat slab building provides many advantages over Conventional slab building, like the use of space, easier formwork, architectural flexibility, and shorter construction time. The structural efficiency of the flat slab construction is obstructed by its poor performance under earthquake loading. In the present study, two Conventional RC slab and Flat slab buildings of G+8 storey building models are considered. Seismic zone III is considered for the analysis. The analysis is done using ETABS software. It is necessary to analyse the seismic behaviour of buildings with the same heights to see what changes are going to occur in conventional slab buildings and flat slab buildings. Therefore, the characteristics of the seismic behaviour of flat slab and conventional slab buildings suggest that additional measures for guiding the conception and design of these structures in seismic regions are needed and also to analyse the performance of buildings having conventional slab and flat slab under seismic loading. The object of the present work is to compare the behaviour of multi-storey commercial buildings having flat slabs and two-way slabs with beams under seismic loads. Present work provides a good source of information on the parameters: storey displacement, storey drift, storey shear, storey stiffness, and time period.

Keywords: Flat slabs, seismic zone.
