| 摘 要： | 大跨度桥梁在低风速下可能会频繁发生较大振幅的涡激共振而导致结构破坏,因而涡激振动已成为大跨度桥梁抗风设计关键问题之一。该文列举了国外大跨度桥梁典型涡激振动实例,并讨论了具有代表性的一些半经验模型,最后针对大跨度桥梁涡激振动提出了基于风洞试验和半经验模型的研究思路。 |
| 关 键 词： | 大跨度桥梁 涡激振动 半经验模型 风洞试验 |

| Abstract: | The bridge could be forced into vibration with large amplitude in low wind speed because of vortex shedding, and is easy to be damaged. Therefore,vortex-induced vibration （VIV） has been one of the most important questions in wind resistance design of long span bridges. This paper introduces some examples of VIV of long span bridges in abroad, and then discusses a few of representative semi-experienced models of VIV. Lastly,one way based on wind tunnel test and semi-experienced model is given here to research VIV of long span bridges in the future. |
| Keywords: | long span bridge vortex-induced vibration semi-emperical model wind tunnel test |
