| 摘 要： | 本文提出一个超静定钢筋混凝土拱的非线性分析方法．这个方法从结构塑性分析的基本原理 出发，考虑了材料的非线性性能，采用了曲杆单元刚度矩阵，变刚度迭代法，杆件截面的数值积 分，断面最大弯矩值的计算以及应力迁移等方法对拱的受荷全过程进行了非线性分析。根据这个 计算方法，编制了相应的计算机程序并进行电算分析，其结果与实测值相比较，两者符合尚好。 |

| Abstract: | This paper deals with the whole process of the translation of structura. behavior in a concrete arch acted upon by loads in seepwise increase A nonl linear finite element method for elasto-plastic analysis of concrete arches ha- been worked out The accuracy pertaining to this method of solution is justified by compntal analysis, the results of calculation are verified by expesiments in the form of a model test their details are also herein discussed. |
