吊桥风激性态及风振研究

On the Wind-Excited Behaviour and its Researches for Suspension Bridges

本文简述吊桥由于风作用引起的颤振、抖振、弛振、涡振等气动弹性现象。评述了五十年来结构工程师和空气动力学家在实验、理论及计算等方面对吊桥风致振动所作的研究。并提出几个目前值得探讨的问题。

In this paper, the aeroelastic phenomena of suspension bridges, such as flutter, buffeting, galloping, vortex-induced oscillation, are briefly introduced. The researches on the wind-induced vibrations of suspension bridges made by structural engineers and aerodynamicists in respects of test, theory, computation, etc. for fifty years and more are discussed. In addition, several existing problems being worth approaching are posed.
