Response of a Single Pile Subjected to Tension Load by Using Softening Models

Аннотация

This paper proposes a single exponential model and a double exponential model to simulate the relationship between pile displacement and unit skin friction developed at the pile-soil interface. Based on the proposed two models, two simple analytical approaches were presented for nonlinear analysis of the response of a single tension pile. A highly effective iterative computer program was developed by using the load transfer method. Comparisons of the present computed results, the calculated results derived from other analytical methods, and measured results were made to demonstrate the reliability of the proposed analytical methods.
