✦ Synopsis

A non-linear three-dimensional finite element procedure is developed and applied for the analysis of pile group foundations. The numerical procedure allows for elastic, non-linear elastic and elastic-plastic hardening behaviour of sand. In order to include the interaction effects involving relative slip and debonding, the thin-layer interface element is used. The predictions for displacements and loads obtained from the numerical procedure are compared with laboratory model test results of a pile group. Displacements, stresses and forces distribution in various components of the pile group are also examined. Furthermore, the effects of the non-linear soil response and relative motions at the interface are identified and discussed. 0363-906 1/86/0 1 0 4 1 -1 8s01.80 0 1986 by John Wiley & Sons, Ltd.
