Seismic Analysis of Multistorey Building with Bare Frame, Bare Frame with Slab Element and Soft Storey at Different Levels of the Building for Various Seismic Zones

Abstract: Soft storey is an unavoidable feature in the multistorey building. It is open for the purpose of parking or reception lobbies and soft storey at different levels of the building for office use. It is also called as stilts storey. Masonry infills are normally considered as non-structural elements and their stiffness contributions are generally ignored in practice, such an approach can lead to an unsafe design. In the soft storey, the inter storey drifts and seismic demands of the columns are excessive that causes heavy damage or collapse of the buildings during a severe earthquake. The masonry infill walls though constructed as secondary elements behaves as a constituent part of the structural system and determine the overall behaviour of the structure especially when it is subjected to seismic loads. In modeling, the masonry infill panels the Finite Element Method is used and the software ETABS is used for the linear dynamic analysis of all the models.
