桥梁风工程研究的现状及展望

桥梁结构因风的作用而遭到破坏的事故屡见不鲜。随着跨径的进一步增大,桥梁结构对风的作用更加敏感,风作用下桥梁结构的抗风性能已经成为影响其设计和施工的控制因素。本文回顾了20世纪国内外桥梁风致振动理论及其控制方面的研究情况,并展望了21世纪桥梁风工程研究的重点问题。

Present Situation and Prospect of Studies on Wind Engineering of Bridges

The wind is an important natural phenomenon,bridges are frequently destroyed by the wind action.With span lengthened continuosly,bridges are susceptive to wind action,the wind resistance becomes a governing factor of their design and construction.In this paper,the studies of bridges on wind-induced oscillation and its control are reviewed,and some important aspects of studies on bridge wind engineering in the 21st century are also prospected.
