Abstract: Structures susceptible to earthquake ground motions and damage them. Mostly the local soil properties ignored and carried out in fixed support conditions to make the seismic analysis simplifier. But, from the past results showed that the earthquake ground motion on different foundation soils influences the response of structures. This paper explores the investigation of earthquake ground motion on three dimensional ten storied reinforced concrete structure supported on different foundations by considering the soil-structure interaction in hard, medium and soft soils and without soil-structure interaction i.e., fixed condition. Structure was modeled and analyzed for linear time history analysis by using SAP-2000 which is finite element analysis procedure and the foundation was modeled by soil springs. The Koyna earthquake (1967) accelerogram selected for the purpose of analysis. The results of this paper shows that the behavior of structure in different foundations and the soil-structure interaction will effect the performance of the structure. There is need to analyze the structure for Time History Analysis to ensure safety against seismic forces.
