Abstract

The soil structure interaction (SSI) is gaining a lot of importance in structural engineering with the development of huge constructions on soft soils like huge concrete and stuff dams, tall buildings, long span bridges, wide tunnels and underground structures which require a very careful attention. In every structure, the super structure and the foundation executed on soil, represent an entire structural system. It will not be analyzed without considering the both. The analysis of a framed structure while not modeling its foundation system and its rigidity could mislead the axial forces, moments due to bending and due to settlement. It is, thus necessary to hold out the analysis considering the type of soil, foundation and above the sub structure i.e. (super structure), that taken as a single unit. In this paper the effect of soil interaction on design parameters in a multi storied building such as, Shear force, Bending moment and settlements have been studied and compared with a conventional case of considered building resting on unyielding supports and the effect of SSI is quantified using finite element analysis.
