| 摘 要： | 索结构传统的几何非线性的求解方法依赖于非常复杂而庞大的切线刚度矩阵,针对这种情况,根据几何非线性计算的基本原理,建立一种在理论上能收敛于精确解的几何非线性求解方法——内力全量迭代法,使计算结果的精度不依赖于切线刚度矩阵；根据计算方法的特点,探讨了在几何非线性计算中索单元的内力计算公式和迭代计算方法；为了保证迭代计算快速...

| Abstract: | Aimed at the fact that traditional methods for geometric nonlinear problems of cable structure dependent on a very complex and huge tangent stiffness matrix,a geometric nonlinear solution method,i.e.,the internal force total iterative method,whose calculation precision can theoretically converge to an exact solution was proposed according to the basic principle of geometric nonlinearity to make the calculation result independent of tangent stiffness matrix.According to the characters of this calculation met... |
