Lateral Deflection of Horizontally Loaded Rigid Piles in Elastoplastic Medium

Abstract

This paper deals with the design of rigid piles under lateral load. In many practical situations pile displacements may be the limiting factor in the design; thus, an allowable displacement analysis instead of an allowable stress analysis may be more appropriate in the foundation design. A nonlinear elastoplastic closed-form solution for the evaluation of the response of rigid piles under lateral load is presented. The derived equations allow determining the lateral displacement and load distribution for a given combination of the applied forces,
