中文摘要
桥梁斜拉索由于风等环境因素引起的振动是斜拉桥中的一个当代问题。在过去的几十年里,这种结构的跨度不断增长,导致拉索变得更长、更灵活。这一点,再加上其固有的低阻尼,使得近年来电缆振动成为一个更加严重的问题。尽管与不同类型的拉索振动有关的机理已经有了更好的了解,各种控制方法也已经被提出并在实际桥梁上实施,但在有或没有补充不同的减振对策的情况下,仍然需要更多地评价拉索行为的动力学和空气动力学方面。
英文摘要
Vibrations of bridge stay cables due to environmental factors like wind is a contemporary issue in cable-stayed bridges. In the past few decades, the growing span length of this type of structure led to longer and more flexible cables. This, combined with their low inherent damping, renders cable vibrations a more serious problem in recent years. Though mechanisms associated with different types of cable vibrations have been understood better, and various controlling methods have been proposed and implemented on real bridges, much is still needed in appreciating the dynamic and aerodynamic aspects of cable behaviour with and without the supplementation of different vibration suppression countermeasures.
