| 摘 要： | 桥梁应具有抵抗风作用的能力,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,通过抗风设计、风洞试验、抗风措施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。

Wind-resistant Design,Wind Tunnel Test and Wind-resistant Measures for Bridge |

| Abstract: | The bridge should be with the capacity of wind-resistant function,especially the large-span bridge with high flexibility,and aerodynamic problems like flutter,buffeting,vortex-induced vibration and so on must be taken into account when designing.By means of wind-resistant design,wind tunnel test and wind-resistant measures to determine wind load and wind-resistant performance of the bridge is the main means of wind-resistant study of large-span flexible bridge. |
