The buffeting performance of the longest double-cantilever state of Zhanjiang Bay Bridge under construction is investigated trough a wind tunnel test of aeroelastic model.
通过气弹模型风洞试验对斜风作用下湛江海湾大桥施工阶段最长双悬臂状态的抖振性能进行了研究,结果显示:对于大跨度斜拉桥梁抖振响应法向风不一定是最不利的情况;抖振响应随风偏角呈非单调变化,最大值可能在0°~15°风偏角范围内发生;抖振响应随风速的增加近似地按两次曲线增加,并且基本固有模态对抖振响应的贡献占到了主要成份;最长双悬臂状态塔顶纵向抖振响应显著地大于裸塔塔顶纵向抖振响应,而两者随风偏角的变化形态也互不相同。
Time-domain buffeting method was used to calculate buffeting-induced responses at the maximum double cantilever stage,which were compared with the wind tunnel test results,and damping coefficients were determined by measured damping ratio of aeroelastic model in the analysis.
采用抖振时域方法,计算最大双悬臂状态时的抖振响应,与风洞试验结果进行对比分析,计算中阻尼系数由气弹模型实测阻尼比确定;由于气弹模型设计中阻尼比相似不能够实现,故修正计算结果,探讨阻尼比对抖振响应的影响;最后采用两种抗风分析方法——阵风系数法和抖振时域分析法,分别对结构进行分析计算。
