摘要
大型通用有限元软件ABAQUS广泛应用于钢筋混凝土结构非线性分析中,损伤塑性模型是其非线性分析的主要混凝土本构模型。总结该本构模型的基本原理和特点,着重分析推导了该模型的损伤因子计算方法,给出计算示例并将该参数计算方法应用到一简支梁有限元分析实例中,验证了该方法的可靠性,可为实际工程计算分析提供参考。
The large universal finite element software ABAQUS has been widely used in nonlinear analysis of reinforced concrete structure. Concrete Damaged Plasticity （CDP） is one of the most important concrete constitutive model in ABAQUS. This paper summarizes the principle and features of the model through theory inferential reasoning and analysis, determines the computational method of concrete damage plastic factors in ABAQUS. To validate this method, a finite element analysis of reinforced concrete simply supported beam is also presented.
