Abstract: In this study, the development of a parallel dynamic finite element program for nonlinear geotechnical analysis is first presented. The program is then used to perform large-scale finite element analyses involving large piled foundation systems constructed in predominantly soft clay ground conditions subjected to earthquake excitation. The research comprises four major components: (1) the setting up of a network PC cluster and the development of a parallel finite element code for large-scale dynamic simulations; (2) the implementation of the key features for seismic finite element modelling, such as the use of solid elements with stress integration for calculating the pile bending moments; (3) parametric studies of the large-scale soil-pile-structure system leading to semi-analytical solutions for the maximum bending moments in the pile group under earthquake loading; (4) extended studies to examine the influence of the superstructure, uneven soil stratigraphy and earthquake motion characteristics on the large-scale pile group effects.
