Seismic Behavior of Reinforced Concrete Piles under Ground

Abstract

This paper reports the results of experimental and analytical investigation on the response behavior of reinforced concrete piles under ground. From the experimental results, it was clarified that the axial load at pile head affects the restoring force degradation and the maximum damage point is dependent on the relative stiffness between the pile and surrounding soil. From the analytical study using 3-dimensional FEM analysis, the experimental behavior could be adequately simulated by the applied method. Further investigations on the shapes or areas of hysterisis loops will be needed for the future application of this method to seismic performance evaluation of the entire structure-pile foundation-soil system.
