风对桥梁结构的影响及作用浅析

On the Effect and Action of Wind on Bridge

桥梁结构因风的作用而遭到破坏的事故屡见不鲜。在风作用下大跨桥梁结构的抗风性能己经成为影响其设计和施工的控制性因素。文中结合桥梁风工程中己知的风的静力、动力特性,简述了桥梁结构在风的作用下的静力及动力响应的主要形式。

The wind is an important natural phenomenon, bridges are destroyed frequently by the wind action. With span lengthened continuously, Bridges are susceptive to wind action, the wind resistance become a governing factor of their design and construction. Combined with known static and dynamic characteristics of wind in structural wind engineering, the article studies the main forms of static and dynamic response of bridge structure under the action of wind, and introduces main research objects and works of bridge＇s wind-resistant design, which to offer theoretical basis for studies on wind engineering of bridge in the 21st century.
