Abstract: In present era, Flat slab buildings are capturing much importance and are commonly adopted for the construction. In high seismic regions, the structural efficiency of flat slab system poses a significant risk due to lowly-ductile. The collapse of the structure is due to brittle punching shear due to transfer of shearing forces and unbalanced moments between slab and columns. In the present work another model is generated by using alternate arrangement of conventional beam slab and Flat Slab building model. The performance of conventional RC Frame building, flat slab RC Frame building and alternate flat slab - beam slab building models with shear walls of G+30 storey under different load conditions were studied and for the analysis, seismic zone V is considered. The object of the present work is to study the performance of alternate flat slab – beam slab structure and compare the behaviour of three structures i.e. conventional beam slab structure, flat slab structure with that of alternate flat slab – beam slab structure under seismic loads. This paper presents good source of information on the parameters modal participation mass ratios, spectral acceleration, time period, storey drift, storey shear, column forces and shear wall forces.

Keywords: conventional beam slab, flat slab and alternate flat slab-beam slab structures.
