Numerical Simulation of Ship Collision on RC Cap with Anti-collision Steel Box Barrier of Over-sea Bridge

摘要

In this paper, an anti-collision steel box barrier used in an over-baycable-stayed bridge is introduced. The whole history of a ship collidingon the cap with anti-collision box barrier is simulated. To clarify theinfluence of pile–soil interaction, the ship-cap-subsoil model isdeveloped. By taking the Fast Fourier Transformation toward theplastic displacement of the RC cap, the dynamic properties of the capare obtained and the damage induced by ship collision is evaluated.Furthermore, the anti-collision efficiency of the steel box barrierinstalled on the cap of the cable-stayed bridge is discussed.
