Paper Title:
Simulation of Bridge Collapse in Virtual Scene Based on Finite Element Analysis
  Abstract

To replicate the scene of bridge collapse realistically, accurately and completely, this paper proposes a scene simulation method of bridge collapse based Finite Element (FE) analysis. On the basis of suitable scene model of bridge, 3D animation of bridge collapse is implemented by the callback of graphics engine Open Scene Graph (OSG) and special effects of bridge collapse are also created by physics engine physX. In addition, terrain and surroundings are added into the scene simulation. The collapse animation proves to be consistent with FE simulation by comparison and the scene simulation is more realistic and complete due to the special effects and the rich scene. This study provides an important reference for analysis of collapse accidents of bridges.
