A Soil Foundation Interaction Model for the Analysis of Pile Group Behaviour
Abstract:This article presents a method for evaluating the distribution of the external loads within a pile group. The model is based on the imposition of the rotation compatibility condition between the pile cap and the piles heads. It includes the soil-foundation interaction which depends, in turn, on two main parameters. The result is a set of clear formulas similar to those provided by the statically-determinate method. Finally, a parametric analysis shows the correlation, by means of an interaction domain, between the axial forces and the bending moments in the pile heads as a function of the lateral loads.

Structural Engineering International (SEI), the quarterly Journal of IABSE, published since 1991, is the leading international journal of structural engineering dealing with all types of structures and materials. SEI offers its readers a unique blend of short profiles on recent structures, and longer, in-depth technical articles on research, development, design, construction and maintenance. Articles are written by practicing engineers and academia from around the world and reflect the high standards of IABSE. IABSE Peer Review stamps are given to papers that have passed through a highly selective review process and demonstrate a significant contribution to the state of structural engineering knowledge.To recognise contributions of the highest quality, an Outstanding Paper Award is presented each year.
