Abstract – Flat slab buildings are commonly used for the construction because use of flat slab building provides many advantages over conventional RC Frame building in terms of economical, use of space, easier form work, architectural flexibility and importantly shorter construction time. The structural efficiency of the Flat slab construction is most difficult by its poor performance under earthquake loading. It is necessary to analyse seismic behaviour of buildings for various heights to see what are the changes are going to occur for the conventional RC frame building, flat slab building with and without drops. In the present study, the analysis of G+9 multi storey buildings having conventional RC frame building, flat slab with drop and flat slab without drop with the model cases of Structure without shear wall, Structure without masonry infill, Structure with considering Equivalent Diagonal Structure, Structure with considering Shear wall, Structure with considering Bracing system. Model of the structure is created by using STADD Pro software. Seismic loads are determined by Response spectrum method. Load combinations are considered as per IS 1893:2002. The seismic evaluation result can be done based on the parameters storey drift, lateral displacement, seismic base shear, natural time period.
