辽宁朝阳珠江桥抗风性能分析

Analysis on Wind-Resistant Behavior of Zhujiang Bridge in Chaoyang City of Liaoning Province

抗风性能分析是斜拉桥设计的重要组成部分。采用有限元分析模型对珠江桥进行了动力特性和抗风性能的分析,通过对最大双悬臂状态和成桥状态的计算分析,表明珠江桥能够抵御百年一遇的大风袭击。

Analysis of wind-resistant behavior is an important part in the design of cable-stayed bridges.The dynamic behavior and wind-resistant behavior is analyzed by using the finite element of the model.The analysis indicates zhujiang bridge could be resistant to the wind attack once of hundred years through the caculation analysis of the maximum double cantilever condition and the bridge state.
