Model and Analysis of Dynamic Characteristic on Cable-Stayed Bridge with FEM

Using the finite element method to establish refined finite element model and the simplified mode of cross line cable-stayed bridge "yan Hong qiao" of the yanshan university. And using ANSYS structure analysis procedures to analysis the vibration characteristic, the first10 order natural frequency and the correspo- nding vibration mode were given. Then, compared and analysis the refined model and the simplified model, the establishment of finite element model in general engineering analysis, correction method and validation suggestions.
