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 dynamic behaviour of soil as well structure should be 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, various methods of soil-structure interactions carried out by various researchers in various region are reviewed.

Finite element implementation of these models requires integration of constitutive relations and load stepping scheme. There have been considerable advances in the integration of constitutive relations. These methods can be grouped as explicit and implicit methods. The superiority of one over the other lies in the context of convergence, accuracy, stability, consistency and simplicity of implementation. In this paper these issues have been addressed in the context of solution of algebraic-differential equations. This approach is extension of the work of Ellsiepen and Hartmaan to modified Cam clay model. Treating nonlinear problem of Cam clay plasticity in this way facilitates to apply all the numerical algorithm of mathematics for the solution of algebraic differential equations. Numerical analysis of this approach gives the better proof for convergence and stability. This approach combines the time inte...

The model is highly nonlinear in nature and in finite element analysis, with a nonlinear material model; an iterative and incremental scheme is required to solve the resulting system of nonlinear equations. Variety of incremental and iterative schemes are developed in the past to integrate the load-displacement curve for nonlinear material models and each of them has advantages and limitations over other while using with a specific constitutive model. As critical state models are nonlinear in nature in the elastic as well as plastic parts of the constitutive relation, the performance of different load stepping schemes for finite element analysis particularly with critical state models is to be done and can be an active area of study. In the present study the review of the literature on the use of various nonlinear solution techniques an...

The program is used to analyze the deformation characteristics of soil under a strip footing. The soil is modeled as layered with uniform elastic constants for each layer. The results of the layered soil are compared with that of an equivalent uniform soil. The elastic constants of the equivalent uniform soil are determined by taking the weighted average of that of the layered soil. The analysis is also performed by modeling the constitutive behaviour of the equivalent uniform soil to be nonlinear. The nonlinear hyperbolic model is used for this purpose and the results are compared with that of linear analysis. The results show that analysis with a linear equivalent uniform soil may underestimate the settlement and overestimate the allowable loads.

Depending on the type of the problem to be solved and the material characteristics involved in the analysis, the constitutive model to be used in the analysis should be selected properly, so that the results close to the real behavior of the analyzed problems. Again, numerical prediction of any constitutive model depends highly on the correct selection of the model parameters. These model parameters for a given material are generally determined from different experimental data. Therefore, selection of a constitutive model and determination of its parameters for a given material are must in any numerical analysis It can be seen from literature that modified cam clay model is mostly used in numerical analysis of geomechanics problems requiring realistic soil models.

From the results obtained, it is found that there is a significant decrease in wall deformation with an increase in the angle of internal friction and its related parameters. The earth pressure results obtained from the finite element analysis shared a unique relationship with that of a conventional method. Both the results showed similar linear behavior up to a certain percentage of wall height and then changed drastically in lower portions of the wall. This trend of behavior is seen in both active as well as in passive earth pressure distribution for all the frictional angle. Hence, after comparing the differences that exist in the res...
