Finite Element Modal Analysis of the Cable-Stayed Bridge

Abstract:

In the process of modeling, ignoring the displacement of the pier directly replaced with fixed constraint, beam elements were adopted to simulate girder and pylon, and link elements were adopted to simulate the cable. The first ten order natural vibration mode and natural frequency were obtained, and the dynamic characteristics analysis of a single pylon cable-stayed bridge was discussed, which can provide certain reference and guidance for solving the problem of the cable-stayed bridge design.
