摘要
本文考虑悬吊结构周边变形的影响,推导出了悬索桥扭转的基本微分方程。并针对两铰悬索桥在水平横向荷载和竖向偏心荷载的作用下进行了分析,给出了实例计算和结论。本文为悬桥的设计计算提供了一种分析计算方法,可供设计者参考。
The effects of the transverse distorsion of suspended structures are considered in this paper,and fundamental differential equation of torsion for suspension bridges is derived.A two-hinged suspension bridge is analyzed under the action of horizontal lateral loads and vertical eccentric loads, and then an example and conclusions are given.The analytic computation approach suggested is avail- able for designers' reference.
