| 摘 要： | 从材料的非线性特性出发,同时考虑截面M和N的相互耦合作用,用非线性有限元分析了拱结构从加载到破坏的全过程,求出拱结构的极限承载力。通过实例分析,验证了本文理论和所编制程序的正确性。

| Abstract: | Based on the nonlinear material constitutive relations of concrete and steel, a program for analyzing the ultimate bearing capacity of arch structures is presented in this paper. The coupling of moment and axial compression of the section is fully considered in the program, with which, the entire process from the starting of loading to failure at ultimate bearing capacity of the structure can be analyzed. Finally, an example for verification and validation purposes is provided. |
