Description

In this paper, the stress transfer mechanism at the pile head joint was studied by FEM. And the stress distribution modeled for safety check was also investigated. In the numerical analyses, debonding and slip on the interface between pile and footing were considered. And also, the effects of the interface friction, the axial load and the embedded concrete depth into pile on the stress transfer were investigated. Based on the results of the analyses, some proposals about the stress evaluation for safety check were made.
