随着现代材料和施工技术的发展,新一代桥梁结构往往柔性大、阻尼小且质量轻,对风的敏感程度也就越来越高。尤其是大跨斜拉桥的拉索构件,极易在风的激励下产生以下几种典型的风致振动:卡门(Karman)涡激共振、尾流弛振,结冰索的弛振、风雨激振等。其中,风雨激振是指在风雨的共同 With the development of modern materials and construction technology, a new generation of bridge structures are often flexible, small damping and light weight, the sensitivity of the wind is also higher and higher. In particular, the cable members of long-span cable-stayed bridges can easily generate the following typical wind-induced vibrations under wind excitation: Karman vortex excitations, wake wake-up, relaxation of icing cables, Vibration and so on. Among them, the wind and rain is the common wind and rain
