斜拉桥的近似分析

The Approximation Analyses of fhe Cable-stayed Bridges

本文采用能量原理,导出斜拉桥的近似解答,并利用逐次渐近法对一座实际桥梁进行数值计算。计算结果同普通程序的计算和实测值吻合良好。所介绍的计算方法既能适用于计算机程序又能用于袖珍计算器的计算。

This paper uses the principle of energy to obtain the approximate solutions for the cable-stayed bridges. The method of successive approximation has been applied to the analyses of the actual bridge. The calculated results are in good agreement with the data of the experimental measurement and with those of the general computer program. The presented method is suitable for both the electronic computor program and the pocket calculator in analysing bridges.
