3-D Elasto-Plastic Finite Element Analyses of Pile Foundations Subjected to Lateral Loading

This paper is a study based on a number of model tests of free- or fixed-headed pile groups, each composed of nine piles, subjected to lateral loading. The model piles made of aluminum were set in dry sand and laterally loaded. The behaviors of the pile groups were then analyzed by the 3-D elasto-plastic finite element method (FEM), which represents a realistic model to simulate the problem. This model includes elasto-plastic soil behavior with...
