Study of Performance and Mechanism of Sandwich Protection Devices for Bridges
In the paper, the rectangular column sandwich plate protective device is developed to resist the impact loading without the bridge's damage. And its behavior is studied. The ANSYS/LS-DYNA, which is non-linear dynamics finite element software, is applied to simulate the crashworthiness performance of the rectangular column steel sandwich plate. The crashworthiness performance factors of the sandwich plate are analyzed so as to optimize the behavior of the sandwich plate. Through the structural optimization, it can be gotten that the rectangular column sandwich plates are better than traditional steel plates in crashworthiness performance.
