大跨刚构-斜拉组合桥抗风稳定分析

刚构-斜拉组合桥是一种新型组合桥梁结构,计算、分析参考资料较少,该文以某大跨刚构-斜拉组合桥为例,进行了该桥的动力特性、抗风稳定分析,分析结果表明,最大悬臂施工状态和成桥状态结构均满足抗风稳定要求,说明该结构体系抗风性能良好,其分析成果为同类大桥设计提供理论参考。

Anti-wind Stabilization Analysis of Large-span Rigid Framework Cable Stayed Composite Bridge

The rigid framework-cable stayed composite bridge is a new composite bridge structure. There is a few calculation and analysis data for reference. Taking a large-span rigid framework-cable stayed composite bridge as an example, the article carries out the dynamic character and anti-wind stabilization analysis of this bridge. The analysis result makes clearly that the maximum cantilever construction status and the bridge status structure all meet the anti-wind stabilization requirement, and explains that the anti-wind performance of this structural system is good and its analysis results provides the theoretical reference for the design of the same bridges.
