The objective of the present study is to estimate the realistic displacements and force quantities in the structural members, accounting for their three dimensional behaviour and non-linear constitutive relations of soil. This demands usage of proper constitutive model for soil and its numerical model, which is validated experimentally. A program has been developed in the present work to compare soil-structure interaction analyses of a three dimensional frame resting on mat foundation for linear and non-linear constitutive relations of soil. For linear analysis initial tangent modulus is used. For non-linear analysis hypoelasticity model is adopted. This hypoelastic model, used, is validated for a plate load test. Results of non-linear analysis are compared with non-interactive analysis and linear analysis to establish its worthiness.
