众所周知，世界各地的斜拉桥主梁通常会出现过度且意外的振动，这通常与风雨同时发生有关。本文基于对从美国两座斜拉桥的长期仪器收集的数据进行比较评估，描述了这些高振幅振动的性质：德克萨斯州休斯顿的 Fred Hartman 桥；以及德克萨斯州休斯顿的 Fred Hartman 桥。以及德克萨斯州亚瑟港的退伍军人纪念桥。这些桥梁中的每一个都表现出高振幅的拉力振荡。研究了各种电缆模式在观测响应中的贡献，并讨论了降雨的影响。
As is now quite well known and documented, cable-stayed bridges around the world are commonly exhibiting excessive and unanticipated vibrations of the main stays, often associated with the simultaneous occurrence of wind and rain. This paper presents a characterization of the nature of these high-amplitude vibrations based on a comparative evaluation of data collected from the long-term instrumentation of two cable-stayed bridges in the United States: the Fred Hartman bridge in Houston, Texas; and the Veteran's Memorial Bridge in Port Arthur, Texas. Each of these bridges has exhibited high-amplitude stay oscillations. The contributions of various cable modes in the observed responses are investigated, and the influence of rainfall is discussed.
