摘要
本文简述了悬索的几何非线性性质和柔性吊桥的计算方法。提出了可以同时考虑悬索弹性伸长、温度影响等因素的试算法。对柔性吊桥的的常用活载,编成程序中微型计算机上约10分钟可求解,适于设计人员使用。
In this paper, the geometrical nonlinear behavior of cablesand conventional computing methods for flexible suspension bridges are briefly described. A trial-and-error algorithm is proposed for cable calculation in considetation of elastic and/or temperature elongation. With a program suitable for designers to calculate cables of flexible suspension bridges under ordinary live lods.problems can be solved on personal computers in about 10 minutes.
