Analysis of a Strip Footing on a Layered Soil Using Element Free Galerkin Method

Abstract

Strip footing is an important type of shallow foundations and is commonly used beneath the walls. Analysis of shallow foundation involves the determination of stresses and deformations. Element free Galerkin method, one of the important mesh free methods, has been used for the determination of stresses and deformations. Element free Galerkin method is an efficient and accurate method as compared to finite element method. The Element Free Galerkin method uses only a set of nodes and a description of model’s boundary are required to generate the discrete equation. Analysis of a strip footing of width 2 m on a layered soil and subjected to a loading intensity of 200 kPa has been carried out. The results obtained are agreeing with the values obtained using analytical solutions available in the literature. Effect of thickness and that of the modulus of deformation of the top layer of soil on stress distribution and deformations have been studied. © 2017, Indian Geotechnical Society.
