| Abstract: | Based on the site test of a rigid frame arch bridge, a set of relevant FEM models of the bridge under overloading have been built in this paper. Programmed computation and reappearing of failure behavior of bracing strut in the bridge under moving-vehicle-induced bridge vibration are realized by means of the visualized simulation, in order to probe the breakdown mechanism of the typical dislocation in the bracing strut. |

| Keywords: | rigid frame arch bridge bracing strut failure behavior vibration visualized simulation |
