摘要
在结构等效外荷载计算、单元杆端抗力向量计算及单元轴向变形方面对传统的CR列式法进行了改进。利用MAT-LAB数学分析软件编制相应分析程序,并通过算例分析比较表明方法具有迭代收敛速度快、计算稳定,精度高的特点。
A new CR formulation is proposed with the related programming flow diagram.Numerical results are presented to demonstrate the accuracy and effectiveness of method.A nonlinear finite element program are developed by adopting MATLAB.This method can be applied to the solution of geometrically nonlinear problems for complicated structures.
