Numerical analysis of a barge collision with bridge pier by using finite element method

Abstract

This study investigates the structural response of bridge piers to collisions with vessels, focusing on factors such as impact stress, pier displacement, and kinetic energy. Using finite element analysis (FEA) simulations, the study considers various barge velocities and pier material properties. The results show that at lower impact velocities (up to 2 knots), the pier undergoes elastic deformation, while at higher velocities, plastic deformation and potential collapse occur. The material's yield strength is crucial, and high tensile steel may be necessary for velocities exceeding 2 knots. The study emphasizes the importance of accurate modeling and considers alternatives for enhancing pier resilience, contributing to the development of safer maritime structures.
