[摘要]基于ABAQUS软件二次开发平台,开发适用于弹塑性时程分析的混凝土及钢筋材料本构。结合现行规范,根据弹塑性时程分析中混凝土压应变及钢筋拉应变实际数值变化,编程实现混凝土构件在经历地震后的损坏等级自动判别,并根据判别结果按照色块由浅至深的原则排序,赋予每根构件不同颜色,使判别构件损伤程度得到量化,并能清晰直观地表达不同构件的损伤程度,为后续性能化设计提供更加便利、准确的可视化计算结果。通过工程算例,对本构及自动量化判别构件损坏等级的方法分别进行单根构件和常规结构两个层面的正确性验证。最后,通过实际工程案例,详细分析和阐述该研究成果的具体应用,对弹塑性计算能输出更为详尽、量化的成果,为施工图阶段性能化设计提供充分的依据。

Abstract:Based on the secondary development platform of ABAQUS software, the constitutive relations of concrete and steel bars for elastic-plastic time-history analysis were developed. Combined with the current codes, according to the reinforced concrete compressive strain and tensile strain numerical changes in elastic-plastic time-history analysis, programs were compiled to automatically identify damage level of concrete components after the earthquake. The judgment results were sequenced in accordance with the principle of color from light to deep, and different colors were endowed to each component to quantify the damage degree of components. It can clearly express the damage degree of different components to provide  more convenient and accurate visualization calculation results for subsequent performance design. Through engineering examples, the correctness of constitutive and automatic quantitative identification of damage grade of component was verified by two levels of single component and conventional structure respectively. Finally, through the actual project case, specific application of the research results was analyzed in detail, to output the more detailed and quantitative results for elasto-plastic calculation and provide sufficient basis for performance-based design construction drawing stage.

Keywords:performance design; ABAQUS software; secondary development; component damage level; quantification; visualization
