Dynamic Characteristic Analysis for Cable-Stayed Bridge

Kun Zhang

Abstract

A cable-stayed bridge is taken for study and a 3-D finite element analysis mode with ANSYS is established,the special dynamical characteristics of this bridge are investigated,including the natural frequency,the features of natural models. The result shows that the large span cable-stayed bridge is long natural cycle,spectrum- intensive, the vibration characteristics clearly show three-dimensional modes and the characteristics of mutual coupling.
