The Application of OpenGL in Bridge Simulation

Using three-dimensional finite element to analyze the bridge structure, the article use OpenGL to research bridge three-dimensional modeling and render realistic graphics. Based on this, we develop bridge structure dynamic simulation system. Take a large bridge engineering for example, and combined with the actual usage situation, we simulate and analyze the following several aspects: traffic flow changes, overloaded vehicles through the bridge, temperature limit state and some situation after several component failure, which to verify structure strength, understand the working performance of the bridge structure, improve bridge design theory and provide technical reference for the similar bridges simulation analysis.
