This study has been undertaken to investigate the effect of soil structure interaction on various properties of R.C. building. In conventional design of structure soil flexibility is ignored which affects the performance of structure. The attempt has been made to describe the effects of SSI on performance of R.C building.. In present study 3 SSI models fixed base, flexible base and elastic continuum model are used. In this study 3 building frames G+5, G+7, and G+10 with 4 bay in both direction were considered. Three types of soil i.e. hard, ,medium hard and soft soil are used for study. The dynamic analysis of structure is carried out using response spectra of IS:1893-2002. The soil flexibility is incorporated in analysis using Winkler approach. Software analysis is carried out using SAP2000 for given structural models. Various structural parameters i.e. natural time period, base shear, roof displacement, beam moment, and column moment are studied. The comparison is made between the approaches SSI models. The study shows that SSI significantly affects the response of the structure.
