Seismic design of pile foundation

Abstract

In seismic design of pile foundation, it is important to evaluate the deformation property of soil and the damage process of a pile member suffering large deformation, since the design for earthquake motions in the new design code is larger than those in the old one. Moreover, as stipulated in the new code, dynamic analysis methods should be used for evaluating structure responses induced by earthquakes. This paper outlines the new seismic design method of pile foundation, the model used in push-over analysis for large deformation and the hysteresis rule of soil-pile system.
