Abstract
Abstract Soil–structure interaction plays an important role in the behavior of structure under static or dynamic loading. It influences the behavior of soil, as well as the response of pile under loading. The analysis is highly essential for predicting a more accurate structural behavior so as to improve the safety of structures under extreme loading conditions. The soil–pile system behavior is predominantly nonlinear and this makes the problem complicated. In a laterally loaded pile the load is resisted by the soil–pile interaction effect, which in turn depends on soil properties, pile material, pile diameter, loading type and bed slope of ground. The difficulty in the accountability of the influencing factors necessitates a careful study on soil–structure interaction problem. The analysis became easier with the debut of powerful computers and simulation tools such as finite element analysis software. A detailed literature review on soil–structure interaction analysis of laterally loaded piles is presented in this paper.

Summary
The pile foundations are adopted to transfer the load from the structure to soil when the structure is embedded in a weak soil stratum. In an axially loaded pile, the load is transferred to the soil through the side friction at the soil– pile interface and base resistance offered by the soil bed. Pile foundations are subjected to significant amount of lateral forces in addition to the vertical forces. When the pile is subjected to lateral loads, the load carrying mechanism changes. The current design practices consider the influence of these two loadings independently and pile designs are carried out separately for vertical and lateral loads. The effects of vertical loads on the piles are well established through these years, whereas studies on vertical piles under lateral loads are limited and are continuing to establish a welldefined method of analysis considering the effect of all the influencing parameters [27]. The present study focuses on the significant factors affecting the soil–structure interaction of laterally loaded pile foundation (LLP). The literatures have been grouped into different categories based on: type of investigations, characteristics of soil, characteristics of pile, and type of loading
