Vortex-Induced Vibration Response of Bridges Considering Both Spanwise Variation of Vibration Amplitude and Correlation of Aerodynamic Forces

  • 摘要:

    为研究非线性气动力跨向振幅依存性和跨向相关性对桥梁涡振响应的影响,首先,引入由振幅多项式表达的桥梁非线性气动力模型;其次,在二维涡振分析方法的基础上,通过理论分析提出同时考虑气动力的跨向振幅依存性和跨向相关性的三维涡振振幅响应分析方法;最后,以主跨1700 m的大跨度悬索桥为例,通过风洞实验识别其主梁在不同风攻角下的竖向涡振非线性气动力参数,进而分析不同风攻角下一阶正对称竖弯模态下的涡振振幅响应. 研究结果表明:当气动力沿跨向完全相关时,在气动力跨向振幅依存性的影响下,三维分析方法得到的各风速涡振响应明显大于二维分析,约大19%;当气动力沿跨向不完全相关时,三维分析的涡振振幅响应比不考虑相关性时降低明显,其中大部分风速下的降低范围在16%~30%,个别风速下约降低70%;证明了考虑气动力跨向不完全相关性和跨向振幅依存性对准确预测大跨度桥梁涡振响应的重要性;本文提出的分析方法对于扭转涡振及高阶模态下涡振分析同样适用.
