摘要
对大型通用有限元程序ABAQUS中的混凝土弥散开裂模型和塑性损伤模型进行了详细的介绍,包括单轴应力-应变关系、裂缝模型、屈服准则、流动法则和滞回规则等。然后对混凝土本构模型中影响结构构件静力行为的关键因素进行了详细的对比分析,并结合采用不同混凝土模型对钢筋混凝土构件和钢-混凝土组合结构构件的受力行为的模拟结果,指出了分析实际结构构件时不同混凝土材料本构模型的适用情况,可供研究设计参考。
The smeared crack and plasticity damage models in general finite element program ABAQUS were detailed introduced,including the uniaxial stress-strain relationship,crack model,yield criterion,flow rules and hysteretic rules.Then comparison and analysis were made on the key factors of concrete constitutive models that have effect on the static mechanical behavior of structural members.The mechanical behavior of reinforced concrete members and steel-concrete composite members under monotonic and cyclic loadings were simulated using various concrete constitutive models,thusly the suitable model could be chosen when analyzing structural members according to the comparison results.
