ABSTRACT: The objective of this paper is to describe a new continuum-based analysis for predicting the nonlinear response of pile foundations, subjected to static lateral loads. In the analysis, the pile is modeled as an elastic Euler-Bernoulli beam and the soil as a continuum with nonlinear elastic properties that is described by a modulus degradation relationship. The soil displacements are assumed to be a product of separable functions and the principle of virtual work is applied to obtain the governing differential equations describing the pile and soil displacements, which are solved numerically using the one-dimensional finite difference method, in an iterative scheme. The reliability of the results obtained from the present analysis is verified with the results equivalent 3-D finite element analysis.

RÉSUMÉ: Euler-Bernoulli élastique et le sol comme un continuum avec propriétés d'élasticité non linéaires qui est décrite par une relation de dégradation du module. Les déplacements du sol sont considérées comme un produit de fonctions séparables et le principe des travaux virtuel est appliqué pour obtenir les équations différentielles décrivant les déplacements de pile et le sol, qui sont numériquement de riposter en utilisant la méthode des différences épicycloïdes unidimensionnel, dans un schéma itératif. La fiabilité des résultats obtenus de la présente analyse est vérifiée avec
