Numerical Modeling of Square Footing Subjected to Eccentric Loading on Geogrid Reinforced Loose Sand

This article aims to study the Performance footing on loose sand soil reinforced with geogrid layers The Load Settlement behavior of the footing under various conditions such as different eccentric value (e), depth of the first geogrid layer (u/B), and vertical spacing between geogrid layers (z/B) was studied. This study presents, the numerical modeling utilizes the finite element package (PLAXIS version 8.2). The soil vertical stress displacement, axial force and footing displacement are discussed by means of a set of finite element results and the validation. The Load carrying decrease with increasing eccentricity values were shown. The optimal spacing between any successive reinforcement layer (z/B) is equivalent to (0.5) for different eccentricity value (e). The PLAXIS output show the failure mechanism developed, and maximum axial force that will be reached in geogrid and footing and the total stress distribution at failure.
