| 摘 要： | 本文首先建立基本的几何非线性方程，然后根据卡氏定理推导出伯努力梁在Ｔ．Ｌ下的几何非线性割线刚度矩阵与切线刚度矩阵的显式，并将两者统一起来，文中同时讨论了各种简化情况，并给出相应矩阵，最后分析了各阶非线性项对斜拉桥的影响。

| Abstract: | In this paper,a basic geometrically nonlinear equation is established firstly;Then according to Castigliano Theorem,plane geometrically nonlinear secant and tangent stiffness matrices of Bernoulli beam are formulated explicitly,and unified in the same form;Diferent simplifications are also discussed in detail,and relevant matrices are presented;A numerical example which analyzes influences of various nonlinear factors on cable stayed bridges is given finally. |
