非线性有限元法在混凝土结构分析中的应用

Nonlinear Finite Element Method Applied in the Analysis of the Concrete Structure

通过对混凝土材料本构关系模型的介绍,阐述了有限元建模的方法。利用有限元软件ANSYS对钢筋混凝土简支梁承载力的有限元分析过程模拟,进行混凝土结构非线性静力计算。分析结果表明,有限元分析结果与试验结果符合得较好,利用有限元非线性分析能够获得正确可靠的结果。

Through the concrete material constitutive relation model, this paper expounds the introduction of finite element modeling method. Using finite element software ANSYS capacity of reinforced concrete beam element analysis process simulation, the nonlinear static calculation concrete structure. Analysis results show that the finite element analysis and experiment results accord with better, the finite element analysis of the reliable results obtained can correctly.
