摘要

This paper focuses on reviewing some conventional soil-structure interaction models based on different superstructures and soils, and an attempt is made to correlate the effect of soil-structure interaction on different kinds of structure and soil types. The civil engineering structures generally have their substructure or some kind of structural element resting on the ground surface. When these systems come under the action of forces, such as seismic forces, neither the structural displacements nor the ground displacements are independent of each other. Soil-structure interaction (SSI) is the process wherein the motion of the structure is affected by the response of the soil and the response of the soil is affected by the motion of the structure. Traditional structural design techniques ignore the impacts of SSI. For light structures in relatively stiff soil, such as low-rise buildings and basic rigid retaining walls, neglecting SSI is feasible. However, the influence of SSI becomes more pronounced for massive structures supported by relatively soft soils, such as nuclear power stations, tall skyscrapers, and elevated highways. Damage sustained in recent earthquakes, such as that from the Kobe earthquake in 1995, has also brought attention to the fact that a structure's seismic behavior is greatly influenced not only by the response of the superstructure but also by the response of the foundation and the surrounding ground.
