Abstract: Many cities exist in seismically hazardous region. As relocation is neither desirable nor practical, these metropolises present the modern engineers with the challenge of creating safe and robustic structures which are capable of withstanding inevitable seismic events. Thus the engineer must evaluate seismic performance in dense, urban environments. In the analysis and design of multi-storey building it is generally assumed that underlying soil is perfectly rigid or bounded to the structure. This postulation leads to gross error in evaluation of overall response under dynamic loads. As a result the accuracy in assessing structural safely during earthquake cannot be accounted accurately. So investigation of energy transfer mechanism from soils to buildings during earthquake is vital for the design of earthquake resistant structures and for retrofitting existing structures. Hence the soil -structure interaction analysis of framed structures is the main focus of this study. The effects of soil-structure interaction are analyzed for typical multi- storey building resting on different soils. The analysis is carried out using a finite element method software package ANSYS under normal loads and seismic loads. Various load combinations are considered as per IS-1893 (part-1):2002 and the mass is assumed to be lumped at various discrete locations. The obtained results are compared with and without soil-structure interaction.
