风荷载对桥梁结构的作用效应研究

Research on effects of action of wind loading on bridge structure

对风荷载的特性进行了介绍,着重分析了其对桥梁结构的静力及动力作用效应,介绍了进行风荷载模拟所采用的方法,并分别计算了静风荷载及脉动风荷载对桥梁结构的影响,充分验证了风荷载对桥梁结构的动力作用不容忽视。

The paper introduces the features of the wind loading,mainly analyzes the static stress of the bridge structure and its dynamic effect of actions,introduces the adopted methods in the simulation of the wind loading,calculates the effects of action of the static wind loading and fluctuating wind loading on the bridge structure,and fully proves that it is not to be neglected for the effects of actions of wind loading on bridge structures.
