SEISMIC EVALUATIONS OF PILE FOUNDATIONS WITH THREE DIFFERENT METHODS BASED ON THREE-DIMENSIONAL ELASTO-PLASTIC FINITE ELEMENT ANALYSIS

摘要

In this paper, three methods for seismic evaluation, namely, a separated method using a dynamic analysis on a sim- plified sway-rocking model (S-R model), a responding displacement method, and a dynamic analysis on a full system, are investigated by conducting a series of static and dynamic three-dimensional elasto-plastic finite element analyses. At first, the validity of a newly developed finite element analytical code DGPILE-3D, which is used throughout this Paper, is checked through a dynamic model test on a pile foundation.
