This Project summarizes estimated seismic response results from soil strucuresintereaction , by supporting on pile foundation for different soil condition , mostly the structure analysis should be able to provide optimum balance between the function and economy , moreover , pile foundations are not designed to resist major or moderate earthquake , for such a designing we are usually done by considering gravity loading only without considering the earthquake loads, which makes these pile foundations vulnerable during an earthquake. It is therefore essential to consider the effect of earthquake loadings, while designing the pile foundations to mitigate the effects of major earthquake. Since earthquake is a natural phenomenon, which generate in the earth’s crust .The magnitude of the seismic loads on the structure during an earthquake depend upon the factors like the mass of the pile foundation, dynamic properties of the pile foundation, the intensity of ground motion and its damping characteristics. The severity of ground shaking at a given location during an earthquake can be minor, moderate and strong .Minor shakings occur frequently; moderate shakings occurs occasionally and strong shakings occurs rarely. This is a major objective of seismic design codes throughout the world. In the present study, finite element analysis of pile foundation supported on different soil types and carried out ,Then the effect of the soil structure interaction are studied. An effort is made to study the effect of seismic loading on these structures. so in this we are considering five storeystructure,for different seismic zones and analysis was carried out by using the software of SAP2000 software, The main aim of the present study is to analyse the five storey building that is supported on pile foundation for different soil conditions and compare the results of maximum displacement, maximum acceleration for all the conditions of the soil and the structure.
