摘要 结构几何非线性分析的增量-迭代方法就是将增量平衡方程式中的荷载向量分解成荷载增量向量和不平衡力荷载向量两个部分,以便对每部分进行单独处理.在荷载增量向量中引入荷载增量因子,就可以通过控制荷载增量因子来控制结构的整个加载历程.将广义位移作为约束方程来确定荷载增量因子,从而形成广义位移控制法.数值实例结果表明,这是一种控制非线性求解的有效方法. The external nodal loads of the nonlinear equation can be decomposed into externally applied loads and unbalanced forces for incremental-iterative nonlinear analysis of structures. Introducing load increment factor in applied loads, the load increment of the whole loading history can be controlled to improve the quality of solutions. In the, paper, the generalized displacement control method (GDMC) is used to obtain the load increment factor,and the numerical results indicate that GDMC is an effective method for nonlinear solution control.
