In every structure, the super structure and the foundation executed on soil, represent an entire structural system. The analysis of a framed structure while not modeling its foundation system and its rigidity could mislead the axial forces, moments due to bending and due to settlement. It is, thus necessary to hold out the analysis considering the type of soil, foundation and above the sub structure i.e. (super structure). Hence the analysis of the single bay single storied building frame resting on soil (Clayey Soil) is taken for present study. The analysis is carried out using “ANSYS 16.0”. In this paper the effect of soil interaction on building frame design parameters as change of modulus of sub-grade reaction from 0.010 to 0.050 N/mm3.Shear force, Bending moment and settlements have been studied for different footing sizes of 1mx1m to 4.5mx4.5m the effect of SSI is quantified using finite element analysis. The following conclusions have been drawn from the study, the shear force and axial force value in the beam and column is constant from finite element analysis are not having considerable difference. The analysis is predicting that percentage difference in bending moment in beam, column and footings are at lower EFS value i.e 0.010N/mm3 at lower footing size 1mX1m is greater than when compared to higher EFS value i.e 0.050N/mm3 at higher footing size 4.5mX4.5m which considers soil interaction. But in case of the footings they undergo some settlement the percentage difference of settlement is 14.41% and 6.72% at lower EFS value i.e 0.010N/mm3 at lower footing size 1mx1m when compared to higher EFS value i.e 0.050N/mm3 at higher footing size 4.5mx4.5m respectively, which considers soil interaction.

Urbanization with its advantages has been constantly attracting people towards towns and cities. Land availability for providing facilities for residential and commercial activities has become a major problem. The engineering solution to this crisis has been addressed through the construction of multistoreyed buildings. Conventional structural design methods neglect the Soil-structure interaction (SSI) effects which is the major concern for risks. The differential settlements and underestimation of foundation pressure are the negative effects of SSI which are to be addressed for urban disaster risk management. In this aspect, an attempt is made in this paper to address some of the issues related to SSI. To quantify the parameters influencing the SSI, A Rectangular footing with L/B (Plan dimensions L, B) Ratios varying from 1.2 to 2 is modeled in ANSYS using SHELL63 elements. The SHELL63 element is capable of modeling the soil underneath the footing. The loss of contact of footing with soil is quantified by Relative Rigidity (RR) and Critical Relative Rigidity (CRR). The analysis is carried out by varying the eccentricity of concentrated load, plan dimension ratio and the Poisson’s ratio of soil. It is found that, as eccentricity of concentrated load increases the CRR decreases from 77 to 81%, for a particular L/B Ratio and Poisson’s ratio of footing. As the poisons ratio µ increases the CRR value decreases from 6 to 8%, for a particular L/B ratio of footing.
