Cyclic Analysis of Laterally Loaded Pile Foundations

Abstract

A three-dimensional numerical analysis, based on the indirect boundary element method, is developed to model the cyclic behaviour of laterally loaded pile foundations embedded in cohesive soils. Phenomena observed in cyclic pile-load tests, such as gapping, backsliding and soil strength degradation effects are accounted for in the analysis. The analysis is capable of solving one-way and two-way cyclic loading problems subjected to load-controlled and displacement-controlled conditions
