摘要
该文首先简述了几何非线性分析的理论,并列举了几何非线性目前求解的主要的方法,最后用牛顿-拉普森法对算例进行求解。计算结果表明,高墩的设计计算,几何非线性的影响不可忽视。
The article briefly describes the geometrical nonlinear analysis theory, takes an example of the main geometrical nonlinear solving method at the present time, and introduces the numerical example by Newton-Rapshon method. The calculation result shows that it can not be to ignore the influence of geometrical nonlinearity on the design calculation of high pier.
