Comparative Study and Punching Shear Behaviour of Flat Slab System

Flat slabs are now a day’s becoming more popular and they are economical as compared to beam-column connections. RC frame buildings are commonly used for the construction. The use of flat slab building provides many advantages over RC frame building in terms of architectural tractability, use of the space, easier formwork under earthquake loads. In the present work flat slab building of G+8 storey building models are considered. The design of flat slab building with direct design method and also we have discussed the results obtained by performing Non-linear pushover analysis on flat slab building of various shapes and different types also by using software ETAB2015. To improve performance of building, it is necessary to analysis the seismic behavior of building, provision of flat slab with drop and without drop on the performance of these two types of buildings. As per IS 456:2000 codes provisions present work gives the information onthe parameters max strip moments, base shear, max storey displacement and storey drift.
