Comparative study of lateral displacement and storey drift of flat slab and conventional slab structures in different seismic zones

In the present era, flat slab buildings are commonly used for construction as it has many advantages over conventional slab buildings in terms of architectural flexibility, use of space, easier formwork and shorter construction time. As due to this old traditional construction net height of room is reduced. Hence to improve aesthetical and structural aspect of multi storey, shopping mall, offices, warehouses, public community hall, hospitals etc. are constructed in such a way were slab are directly on columns. This types of slab directly supported on column is termed as flat slab. The main objective of the present work is to compare the lateral displacement and storey drift of solid flat and conventional slab structures in seismic zone II, III, IV and V with type II medium soil and to study the effect of height of buildings on the performance of these buildings under seismic forces. For this purpose 5, 10 and 15 multistoried buildings of fixed structural and material properties having flat slab with and without drop panel and conventional slab have been considered. Linear dynamic response spectrum analysis was performed on the structure to get the seismic behavior.
