“…Strength considerations primarily involves ensuring that the loads on foundation remain well below the allowable bearing capacity specified underseismic conditions and the serviceability of foundation is ensured by designing the substructure as per the estimated permanent ground deformation. [5] The responses of structures during an earthquake are usually analysed assuming that the foundations are rigidly fixed at their base. Such analysation generally anticipates overturning moment at the base that transcends the maximum allowable overturning resistance because gravity force, meaning that a part ofmat foundation would occasionally exhilarate during an earthquake.The nonlinear behaviour of shallow foundations during excessive amplitude earthquake-induced loading can disperse the seismic energy by the soil yielding mechanism underneath the foundation .The upliftment along with the yielding causes extreme fugitive and enduring deformities such as sliding, rocking andsettlement [6].…”

As we know,shaking due to seismic waves causes damage to buildings. The damage maybe influenced by the characteristics of soil in the affected area.The objective of the paper is to show the effect of the earthquake on different types of foundations such as shallow, mat/raft, pile and structures like gravity dam, arch dam etc. The reaction of soil to the loading of the building when a building undergoes an earthquake disturbance as a behaviour of deflection is known as the soil structure interaction. The movement of ground during theearthquake induces kinematic and inertial loading which decreases the bearing capacity and increments the settlement of shallow foundations. In seismic regions, where kinematic interactions have been observed, the mat foundations experiences overturning moments. Pile foundations are influenced by both kinematic and inertial interactions which causes many failures. The convoluted oscillating arrangement of acceleration and ground motion in a gravity dam,developing ephemeral dynamic loads because of inertia of dam and confined water is the seismic activity generated in these dams. The arch dam foundations undergoes effects of inertia and flexibility due to the propagation of seismicwaves.

Abstract. Recent studies have shown that the e ects of Soil-Structure Interaction (SSI) may be detrimental to the seismic response of structure, and the neglect of SSI in analysis may lead to an un-conservative design. The objective of this study is to simulate the performance of multi-storey building-foundation systems through a Winklerbased approach. Four typical steel Moment-Resisting Frame (MRF) buildings on three soil types with shear wave velocities of less than 600 m/s subjected to actual ground motion records of varied hazard levels are modeled with and without SSI. It is observed that the performance level of models supported by exible foundation, particularly in an intense earthquake event, may alter signi cantly in comparison to xed-based structures. Moreover, for MRFs on soft soil, the nonlinear foundation is found to have a signi cant e ect on the force and displacement demands. This indicates the necessity for consideration of exible foundation behavior in the modern design codes in order to accomplish a more economic yet safe structural design.

“…Following these pioneering works, several authors have tackled the SSSI problem through different methodologies, such as analytical solutions, numerical models and experimental tests. As a full literature review is out of the scope of this research, the authors want to refer the interested reader to the work of Lou et al [4], where a complete survey of the SSSI studies can be found. A related problem that has been addressed more recently [5][6][7] is that of the site-city interaction (SCI).…”
