Abstract

In order to clarify the applicability of fiber model to pile-soil interaction analysis. numerical evaluations of the past loading test results are synthetically performed using 3D FEM analytical method including the local behaviors between pile and soil. It can be concluded that the local separation between pile and soil (e.g. no tensile stress exists) is effective on the response behavior of RC piles, especially in the cases that the maximum damage occurs at deep position of the pile. In addition, the accuracy of the adopted model is verified for applying to the response evaluation of pile-soil system.
