Abstract:

In the conventional analysis of a multi-storey building frame we consider the frame as an isolated structure which is not affected by the nature of soil, but practically the building frame rests on a settable soil mass. So it is necessary to consider the differential settlement of the foundation which may change the forces of the structural member significantly. In the soil structure interaction analysis, the building frame, foundation and soil mass consider as a complete structure which is subjected to different types of loads like dead load, live load, wind load, seismic load etc. Seismic load is essential in case of multi-storey building.In the present work, the linear interaction analysis of a three-bay eight-storey plane building frame-homogeneous soil system under seismic loading has been carried out using the software ANSYS based on finite element method. The frame and the soil mass both have been considered to act in a linear elastic manner. The change in axial forces and bending moments in the columns due to differential settlements of the soil mass is investigated.
