独斜塔斜拉桥风振效应分析

Analysis on flatter effect cable-stayed bridge with single pylon

以马新斜拉大桥主桥为背景,运用二维颤振理论,并建立结构有限元计算模型对该桥的动力特性进行了分析,得到了周期和振型特征,并与设计要求作了对比,完成了对该桥的研究。

With the background of Maxin Bridge, the article analysis the bridge dynamic by using finite element method, and reached the periods and vibration model features of the bridge. Applying theoretical analysis of two-dimensional flutter, the article compared with the design require- ments. Having completed the analysis of the bridge.
