Abstract: Shear walls are a type of structural system that provides lateral resistance to a building or structure. They resist inplane loads that are applied along its height. The applied load is generally transferred to the wall by a diaphragm or collector or drag member. The seismic motion that reaches a structure on the surface of the earth is influenced by local soil conditions. The subsurface soil layers underlying the building foundation may amplify the response of the building to earthquake motions originating in the bedrock. Three types soil are considered here:Hard soil ,Medium soil,soft soil.In this paper, a typical multi storey building is analyzed using software ETABS by dynamic (Response Spectrum) analysis. All the analyses has been carried out as per the Indian Standard code books. Analysis is done on thirty storey high and provided with box shape Shear Walls at the center under different type of soil. Seismic performance of building model is evaluated. This study is done on RC framed multistory building with RC shear walls with fixed support conditions In present work, thirty storey buildings for earthquake zone V in India. This paper aims to study the behaviour of reinforced concrete building by conducting dynamic analysis for most suited positions and location of shear wall under different type of soil . Estimation of structural response such as; storey displacements, storey moment ,storey shear, storey drift , Pier Forces, column forces is carried out. Dynamic responses under zone V earthquake as per IS 1893 (part 1) : 2002 have been carried out. In dynamic analysis; Response Spectrum method is used.
