Comparative Study of Flat Slab and Conventional Slab Structure Using ETABS

civil Engineering

In today’s construction activity the use of flat slab is quite common which enhances the weight reduction, speed up construction, and economical. Similarly from the beginning conventional slab has got place in providing features like more stiffness, higher load carrying capacity, safe and economical also. As the advancement era began practice of flat slab becomes quite common. In the present dissertation work a G+9 commercial multi-storeyed building having flat slab and conventional slab has been analysed for the parameters like base shear, storey drift, axial force, and displacement. The performance and behaviour of both the structures in all seismic zones of India has been studied. In the present work the storey shear of flat slab, the axial forces on flats slab building, the difference in storey displacement of flat and conventional building are approximately calculated by using ETABS software. The present work provides reasonable information about the suitability of flat slab for various seismic zones without compromising the performance over the conventional slab structures. The main objective of the present work is to compare the behaviour of multi storey buildings having conventional RC frame, flat slab without drop and to study the effect of height of building on the performance on these types of buildings under seismic forces. Linear dynamic response spectrum analysis and nonlinear dynamic time history analysis is performed on the structure to get the seismic behaviour.
