The objective of this study is to assess the comparative seismic performance of flat slab buildings vis-a-vis grid slab buildings. Dynamic analysis of three different high rise buildings having 12, 15 & 18 stories is performed using response spectrum method for all four seismic zones of India, as categorized by the Indian code for earthquake resistant structures. The assessment of the seismic response is based on the maximum inter-story drift, roof displacement, Time period and the base shear. E-TAB v9.7.3 software is used for the analysis. It is observed that the seismic performance of grid slab buildings was better as compared to that of flat slab buildings.
