| Abstract: | Based on a practical engineering of Houzhu Bridge of Quanzhou, the force of ship collisions with anti-collision island and its internal stress distribution and deformation are studied by model testing and nonlinear FEM analysis. The testing results show that the design ship collision force is about 30 percent higher than the experiential value expected. The results of FEM analysis show the damage mode of the anti-collision island is in good accordance with the one expected. |
