摘要
大跨桥梁发展的趋势是更长大、更轻柔化。随着桥梁跨度的增大,结构风致振动问题将愈加突出,因而风振控制的重要性也愈加显现。本文在简要回顾国内外关于桥梁两种主要风振——颤振及抖振控制研究的基础上,对作者在这一方向中的研究成果作了介绍。
Long-span bridges are tending towards longer and more flexible. With the increase of bridge spans, study on wind-induced vibrations of these bridges has been a problem of great concern. In this paper, the achievements of study on wind-induced vibration, especially on flutter and buffeting, of long-span bridges gained by the authors are introduced based on a brief review of the recent research situation in this field.
