Study on seismic performance assessment of precast concrete pile foundation based on dynamic analysis

Abstract

This paper presents a study on the seismic performance assessment of the precast concrete pile foundation based on dynamic analysis. The precast concrete pile foundation for existing bridges exhibits the inferior seismic performance. In order to evaluate the seismic performance of those foundations rationally, parameters of structural patterns and geological conditions were discussed through the analytical results. It is found that seismic performance of those foundations is dependent on ground conditions of the layer at pile head, and the pile-arrange pattern.
