To simulate bridge collapse realistically and assist the investigation of bridge collapse accidents, a modeling method of bridge collapse in Open Scene Graph (OSG) graph engine based on Finite element (FE) simulation is proposed. For FE simulation using 3D solid elements, the main questions of modeling, such as scene hierarchy, drawing method and texture mapping, are discussed. A study case shows the bridge model in this paper is with realistic graphics, render efficiency and simulation controllability. The 3D virtual scene simulation using the modeling method proposed in this paper has the same accuracy as FE simulation, but is more realistic and complete than FE simulation and provides a graphic support for the analysis of bridge collapse accidents.
