Modeling of laterally loaded piles using embedded beam elements

Abstract

Realistic modeling of pile groups requires the use of complex nonlinear 3D simulations, usually with full discretization of pile continuum. In order to reduce the complexity of these models, as well as the computation time, in past years an embedded beam element has been formulated and implemented into FEM computer codes such as PLAXIS 3D. This concept was originally intended for modeling axially loaded piles and pile groups, while its performances under lateral loading conditions are not fully investigated. This paper presents the overview of different modeling techniques of laterally loaded pile groups using FEM. The possibility of using embedded beam model for this problem, as well as its limitations, have been discussed.
