【摘要】 金马大桥是一座斜拉桥与T构的协作体系结构 ,斜拉桥的主梁采用梁板结构而T构采用箱形截面。两种不同截面形式的连接是否合理成为该种结构体系是否可行的关键。对接头部位的构造进行了分析 ,提出一种合理的接头构造形式并对其受力做了分析 ,采用了有限元法与光弹试验相结合的方法 ,证明了接头受力的合理性 ,为设计提供了依据更多还原

【Abstract】 Jinma bridge is a cooperative structure system of the cable stayed bridge and the T shape frame. The main beam of cable stayed bridge adapts girder structure, and the T shape frame is box section. It is key point for the structure system that the joint of two sections is reasonable or not. After analyzing the structure of joint zone it puts forward and analyzes a reasonable joint method. Using finite element method and photoelastic experiment prove the rationality of joint forcing, which provides the foundation for design.更多还原
