摘要
运用ANSYS进行钢纤维混凝土结构非线性分析,以钢纤维混凝土梁为例,详细探讨混凝土、钢纤维混凝土和钢筋的本构模型、单元特性以及有限元模型的建立,采用APDL语言参数化建模,编写通用命令流,完成非线性分析,并与试验结果进行比较.结果表明,运用ANSYS中混凝土材料的Solid65单元和相应的本构关系及强度准则,并将其与ANSYS中其他单元组合使用,可以得到令人满意的结果.
In this paper, the constitutive models of concrete and reinforcement, as well as the properties of their element and the models of FEA are discussed. Models are created in APDL language; and nonlinear analysis for reinforced concrete beams containing steel fibers is carried out by using the large general structural analysis software ANSYS. If Solid65 is used together with other elements in ANSYS, and proper constitutive equation and failure criteria of concrete are adopted, the simulated results correspond well to the experimental results.
