STUDY THE BEHAVIOR OF A MULTI-STOREY BUILDING UNDER SEISMIC CONDITIONS

Abstract

sometimes become the cause of disaster, in case of earthquake. Therefore seismic analysis and design is required to make the structure earthquake resistant and dynamic analysis of building structures by Response Spectrum Method is most suitable. In the present work, the various aspects of dynamic analysis are considered. Seismic analysis according to Indian codes is studied and an overview of the topic is developed. Modelling of a multi storyed building is done in STAAD Pro software. The material property, loading details and soil types are assigned to the model, and then its dynamic analysis is carried out. Then displacement and peak storey shear at each floor for different zone factor and soil type are obtained from output file of STAAD pro. Also, the base shear for different modes is obtained for different zone factor and soil type. Then comparison of base shear, peak storey shear and displacement between different response reduction factor while keeping the zone factor and soil type constant is carried out and % variations of output parameters with variation of response reduction factor are plotted. Then finally the outcomes and results are stated, comparisons are made.
