In this paper, the effect of axial force have been considered by using Newton method to modify the solution. Because of the olthogonality properties of vibrating mode functions.

本文以梁的振型函数为位移试函数,基于最小势能原理,采用拉氏乘子法强制满足桥墩处主梁的位移条件,对斜拉桥拉索的轴力,塔架和主梁的弯矩,轴力及挠曲位移作了计算。文中考虑了梁、塔的轴向力对挠度的影响(即梁——柱效应),采用牛顿迭代法修正求解。由于利用了梁振型函数的正交性,刚阵形成简单。计算实例表明,只需取试函数的前几项迭代3—5次,使可得到较满意的解答。本法计算量,未知量均很少,可在微机上求解。
