Abstract: Structural failures during earthquakes often occur due to inadequate analysis and design practices. Typically, foundations are designed based on superstructure loads, site conditions, and seismic zoning. Conventional analysis assumes no interaction between the structure and the supporting soil, with structural engineers assuming fixed supports and geotechnical engineers designing foundations independently. In reality, the interaction between soil and structure plays a crucial role, as both deform under load and must act compatibly. This study reviews the dynamic behaviour of framed structures supported on various foundation types, emphasizing the importance of SSI. Analytical, numerical, and experimental approaches from recent literature are discussed, highlighting current challenges and future research needs in SSI modelling.
