| 摘 要： | 协作体系斜拉桥是一种跨越能力大、结构新颖的斜拉桥结构形式,该体系的抗风性能及接头部位的处理是设计人员十分关注的问题.文中以金马大桥为实际工程背景,对斜拉桥与T构间接头处的构造形式进行了探讨,对剪力铰和连续截面两种不同的连接方式所形成的协作体系斜拉桥进行了抖振响应分析,比较了两者在变形及受力方面的特性,为今后类似工程的设计提供了一定的参考.

| Abstract: | Cooperative system cable stayed bridge is a long span and novel structure form of cable stayed bridge,the anti-wind capacity and joint zone of which draw much attention of designers.In this paper,the structure forms of the joint zone between cable-stayed bridge and T frame are studied and discussed for Jinma bridge.Then buffeting response analysis of two different cooperative system cable stayed bridges with different joint forms are carried out,and the mechanical characteristics under loadings are compared.The results provide a valuable reference for the design of similar project. |
