Abstract
The analysis of soil-structure interaction problem is affected by various structural parameters and behavior of the soil mass. The nonlinear soil behavior plays a vital role in the redistribution of the forces in superstructure. Consequently, the forces in the frame members significantly get altered due to differential settlement of the soil mass. The study of interaction behavior due to these parameters requires the use of finite element method. The physical modeling of the interaction system is achieved by use of variety of elements. The unbounded domain of the soil mass is discretized with coupled finite-infinite elements and proper location of truncation boundary is established. The structural parameters like relative stiffness of columns and beams, type of connections between beams and columns, bay width, storey height, number of storeys, number of bays, type of soils, loading conditions and many other factors have significant influence on interaction behaviour of building frame-soil system. The present study investigates the effect of change of bays and storeys on the linear and nonlinear interaction behaviour of plane frame-soil system and the forces in the frame members, vertical settlements and contact pressures below foundation beam have been evaluated. The constitutive law of nonlinear behaviour of the soil mass is modeled using hyperbolic model. The effect of these parameters on differential settlement of soil mass is also discussed.

Effect of Geometrical Parameters on Nonlinear Soil-Structure Interaction Behavior of Plane Frame-Soil System

The analysis of soil-structure interaction problem is affected by various structural parameters and behavior of the soil mass. The nonlinear soil behavior plays a vital role in the redistribution of the forces in superstructure. Consequently, the forces in the frame members significantly get altered due to differential settlement of the soil mass. The study of interaction behavior due to these parameters requires the use of finite element method. The physical modeling of the interaction system is achieved by use of variety of elements.
