As a result of population boom and scarcity of land, buildings are constructed very close to each other. This is the major issue especially in the case of developing country where housing colonies are developing in the big cities as well as in the countryside, making the study of soil-structure interaction as an essential part of structural design process. The effect of soil, on which the structures stands, especially in the highly seismic zones, the dynamicbehaviour of soil as wellstructureshouldbe well known by the designer. The effects of structures standing in a close vicinity to each other is the main issue of soil-structure interactions as well as structure-soil-structure interactions. In this paper, variousmethods of soil-structure interactions carried out by various researchers in various regionare reviewed. Key words: - Population boom, Countryside, Soil- Structure Interaction, Seismic Zones I. INTRODUCTION Civil engineering structures generally require some type of structural element which is in direct contactwith soil. In order to estimate the accurate response of the superstructure it is necessary to consider the response of the soilsupporting structure, and is well explained by the soilstructure interaction (SSI) analysis. Various attempts have beenmade by various researchers to model the SSI problem analytically; however thesoil nonlinearity, foundation interfaces and boundary conditions make the problem more complex and computationally costlier. Most efficient and accurate modeling of the unbounded soil medium hasbeen of long- standing interest in the mind of researchers for the dynamic soil structure interaction (SSI) problems. The methods availablefor the analysis of SSI problems can be classified into two groups:i.e. direct method and substructure method. In the direct method of SSIanalysis, the artificial boundary has to be placed sufficiently far fromthe soil-structure interface because approximate or local boundaryconditions are imposed on this boundary. This leads to an increase inthe number of degrees of freedom (DOF) and the computationaleffort, although the direct method itself is computationally efficient because the interaction force-displacement relationship involved is local in time and space. On the contrary, in the substructuremethod, the boundary conditions imposed on the interaction horizonare rigorous, making the force-displacement relationship global bothspatially and temporally. A large amount of data also need to be processed,which results in expensive computations, especially for large-scaleproblems. II. REVIEW OF AVAILABLE LITERATURES Jonathan et al. (1999) proposed the well- definedprocedures for simulating the inertial soil structure interaction effects with respect to seismic structural response. Their analysis procedure and data’s are similar to that of provisions provided in standard building codes along with the consideration of the site influence conditions, foundation embedment, flexibility, and shape of the foundationimpedance. The process of implementing their analysis procedures and
