LOAD ON PILES FOR PRECAST CONCRETE BEARING WALL STRUCTURE

Abstract

This article presents results of a study on load distribution on pile foundations of precast concrete structure. In this study, loads on pile foundations for precast concrete walls were analyzed using a non-linear finite elements program. Two topics were covered in this study: one was the effects of connection stiffness on pile load distribution, and the other was the comparison of stiffness of precast wall to that of cast-in-place wall. Results of the study showed that connection stiffness has significant effects for long wall only, whereas for short wall the effects were not significant. Results of the study also showed that the overall stiffness of long cast-in-place wall was higher than that of precast wall. The difference between wall stiffness increased with decreasing pile stiffness.
