| 摘 要： | 以主跨278 m,桥面宽4 m的钢桁架加劲梁窄面悬索桥为工程背景,对大跨窄面悬索桥的风致抖振响应进行了有限元仿真模拟分析,并对可能影响桥梁抖振响应的几个关键的影响因素进行了分析,研究了大跨窄面悬索桥的抖振响应特点,得出结论:对于大跨窄面悬索桥结构,在动力时程分析过程中考虑大变形效应,结构主梁的抖振响应脉动幅值均变小,且...

| Abstract: | Based on the steel truss stiffening girder suspension bridge which has 278 m main span and 4 m width,the finite element simulation and the analysis of several essential influencing factors of the wind-induced buffeting response for long-span and slender suspension bridge were carried out to find out the buffeting response characteristics of the bridge.It is concluded that for long-span and slender suspension bridges,buffeting response is decreased in vertical,horizontal and torsional directions especially f... |
