浅谈桥梁抗风设计

On Structural Wind-resistant Design of Bridge

桥梁结构因风的作用而遭到破坏的事故屡见不鲜。风作用下桥梁结构的抗风性能己经成为影响其设计和施工的控制因素,结合结构风工程中己知的风的静力、动力特性,研究了桥梁结构在风的作用下的静力及动力响应的主要形式,为其进一步的研究提供了理论基础。

The wind is an important natural phenomenon, bridges are frequently destroyed by the wind action, bridges are susceptive to wind action, the wind resistance becomes 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 work of bridge＇s wind-resistant design, which to offer theoretical basis for further research.
