Abstract
:Inelastic response of the buildings are often developed without considering soil structure interaction where the base is assumed to be fixed. The present study presents the soil structure interaction and ambiguity effects in soil properties such as Poisson’s ratio of the multy storied framed structure in three different types of soil, namely soft, medium and hard soil with fixed and flexible base considering soil structure interaction. In this paper, a model of G+10 storey building with fixed and flexible base considering raft foundation was analysed using SAP2000. From the analysis, it was observed that the results of lateral displacement, storey displacement, base shear, moment values and the time period were on higher side in the flexible base considering soil structure interaction. The requirements of considering soil structure interaction during design of structure can be understood.
