摘要
针对抖振、涡激共振、风雨振等风致振动对大跨度桥梁的结构安全形成不可忽视的影响,探讨了大跨度桥梁抗风设计原则与风致振动的控制,提出了改善桥梁结构和增加机械阻尼等方法.
With the develop of large-span bridges, the control of wind-induced vibratory is very important. The main formsof wind-induced vibratory of large span bridges generally include buffeting, vortex-induced resonance and vibration storm, whose impact on the structural safety can not be ignored. This paper discusses the design principles of large span bridges and the control of wind-induced vibration, and then comes up with some measures to improve the bridge structure and increase the mechanical damping.
