Due to increasing in population as well as less availability of land it is necessary to construct multi-storey building. Underground storeys (basements) are an important component of urban building construction for reducing parking problem. To study the behaviour of this type of building under seismic loading is main objective of this analysis. When we are considering underground storeys it is necessary to consider Soil-Structure Interaction effect. The dynamic interrelationship between the response of the structure is influenced by the motion of the soil and the soil response is influenced by the motion of structure is called a soil structure interaction. Here, we are considering Soil-structure Interaction effect on building with vertical irregularities. G+14 storey building is selected for modelling and analysis. Response spectrum and Time History Analysis is done in SAP2000. Response spectrum analysis and Time history analysis is carried out according to IS 1893:2002 and acceleration data of past earthquake respectively. The effect of SSI on various structural compound like time period ,base shear, roof displacement ,are studied and discussed.
