Abstract. An extensive study is performed on the behavior of raft foundation considering soil structure interaction. The foundation is modelled using SAFE2016 software considering thick plate. A parametric study is carried out on raft foundation using finite element method considering static load condition. Several parameters, such as thickness of raft, modulus of subgrade reaction, load pattern, soil condition affect the soil-raft-structure response. The study revealed the analysis of the structure on raft foundation system considering the raft and soil properties. Displacement of raft foundation is decreased as increased in raft thickness. However, displacement of raft foundation is increased as decreased in subgrade modulus. Maximum soil pressure is decreased with increase in raft thickness. Soil pressure is increased with the increase of subgrade modulus. Punching shear ratio for raft foundation is decreased as increased in raft thickness. Punching shear ratio for raft foundation is decreased slightly as increase in subgrade modulus. Thickness of raft is important for designing raft foundation. The soil conditions are affecting the raft characteristics like deflection, soil pressure, punching shear. Increase of edge distances from the center of column decreases the upward soil pressure intensity.
