| Abstract: | By means of the software ANSYS/LS-DYNA, the process of numerical simulation of a 3 000 DWT cargo ship colliding with the steel casing for the pile cap of a cable-stayed bridge is demonstrated. The method to build FEM of structures is introduced. The laws and characteristics of the collision forces, energy exchange and shock response of the steel casing are analyzed, which can be used as technical and theoretic supports to provide protection to similar bridges. |
