钢桁架主梁悬索桥静风特性研究

Investigations on the Static Aerodynamic Performanc of Steel Truss Girder Suspension Bridge

采用风洞测力试验方法,对某钢桁架悬索桥成桥及施工状态下的不同攻角下的三分力系数的测定及静风响应特性进行了研究,获得了该主梁截面的失速风攻角,得到了不同攻角下三分力系数随截面变化的关系。

Base on the wind tunnel test response are investigated on completion and different attack angle. The stall angle and the cross section are studied. method for measuring forces, the aerostatic coefficients and aerostatic construction conditions of steel truss girder suspension bridge under three - component coefficient changing with attack angle on diffent
