协作体系斜拉桥的结构分析

Structure Analysis of Cable-stayed Bridge of Cooperative System

协作体系斜拉桥是一种较为新颖的斜拉桥的结构形式 .对于工程中常见的独塔及双塔斜拉桥 ,从结构的刚度和受力分析着手 ,对协作体系斜拉桥与普通的斜拉桥进行较为全面的比较 ,得出协作体系在变形及受力方面的特性 .根据这一特性 ,提出了对工程设计的建议 .

Cable-stayed bridge of cooperative system is a relatively novel structure form of cable-stayed bridge. For single-tower and two-tower cable-stayed bridge that are often used in practice, this paper compares the structural characteristic in structural stiffness and internal force of cooperative and normal system. According to the deduced characteristic of cable-stayed bridge of cooperative system, the author gives some proposal on design of this kind bridge.
