Abstract：A computational model for pile-supported structures，which can duly consider the pile-soil interaction effect，is established by use of the finite element method，and its numerical implementation is made in time domain，accordingly. For the convenience of comparative analysis，the substructure method for seismic response analysis of pile-soil-structure system is briefly presented. Then a comparative study is performed for an engineering example and it is shown that the results obtained by the finite element method is common with the computational results achieved by the substructure method. These numerical results and findings will offer instructive guideline for earthquake-resistant analysis and engineering design of the pile-supported structures in practice.
