本文用非线性弹性增量理论编制了钢筋混凝土平面问题非线性有限元受力全过程计算程序,并对钢筋混凝土浅梁和深梁进行了计算。在此基础上对迭代收敛条件、混凝土开裂单元处理方法、开裂单元剪应力释放及不同迭代解法进行了计算比较。并归纳山一些初步意见。
In this paper, the nonlinear finite element loading process of reinforced concrete plane problem is programmed using the nonlinear elastic incremental theory. The shallow and deep beams of reinforced concrete are calculated. Based on this, the iterative convergence conditions, concrete cracking element processing methods, shear stress release of cracking elements and different iterative solutions are calculated and compared. And summarized some preliminary opinions on the mountain.
