| Abstract: | The article uses Ansys finite element software to analyze the dynamic characteristics of the new half-through steel truss self-anchored suspension bridge, and puts forward the more correct method to establish the model to make the calculation result able to meet the requirements of the engineering analyzing accuracy. The article lists this new bridge having the representative vibrating type and carries out the analysis to provide the practical basis of the dynamic performance for the projects. |
