Abstract:

In this research article under seismic loading effects the soil underneath and it causes development of stresses in soil which in turn shown an impact on the frame intact. The stresses in the soil effects the structure motion and in reverse the structure motion alters the soil response. This is called Soil-Structure-Interaction. A stress developed in the soil finds a way to move to free space, whereas when a frame located on a soil mass receives the total stresses through foundation and delivers direct and shear stresses through its grain mass and this grain skeleton behaviour depends on many factors like void ratio and confining pressure. These effects are to be considered most important as they show heavy impact on the super structure. The seismic effect on the super structure depends mainly on soil amplification effect, inertial and kinetic interaction.
