Application of Non-Linear Fiber Section Model on Spun Piles With and Without Concrete Infill Subjected to Cyclic Loading

Abstract

This numerical analysis study predicts the behavior of spun piles with and without
concrete infill under cyclic flexural loading and constant axial load. A fiber
section using STKO pre- and post-processor for the OpenSEES program was
employed. Spun piles were modeled using displacement-based beam-column
elements with distributed plasticity and cyclic loading procedures with
displacement control. The numerical method proposed for this research was
verified by comparing it to reliable experimental results.
