摘要:

桥梁应具有抵抗风作用的能力,风对桥梁的作用不单纯是平均风的静力作用,特别是大跨度桥梁,其柔性较大,设计时必须考虑颤振、抖振、涡激振动等空气动力问题.通过风洞模型试验来确定桥梁风荷载和抗风性能是大跨度柔性桥梁抗风研究的主要手段.风洞试验主要包括桥梁节段模型静力试验、节段模型动力试验、全桥气动弹性模型试验等几个方面.

Abstract:

The bridge should have the ability to resist the action of wind, the role of wind on the bridge is not simply the static effect of the average wind, especially the long-span bridge, its flexibility is large, the design must consider the flutter, jitter, vortex vibration and other aerodynamic problems. Determining the wind load and wind resistance performance of bridges through wind tunnel model tests is the main means to study the wind resistance of long-span flexible bridges. The wind tunnel test mainly includes bridge segment model static test, segment model dynamic test, full bridge aeroelastic model test and other aspects.
