[摘要]对《混凝土结构设计规范》(GB 50010—2010)中混凝土损伤本构关系模型进行局部改进。进而结合常用的结构非线性分析软件ABAQUS,讨论了本构关系状态量的换算关系式,同时基于ABAQUS软件的计算结果对改进的混凝土损伤本构关系模型进行了验证,并指出了其应用过程中的若干注意点。

Abstract:Local improvements were carried out on concrete damage constitutive relation model in Code for design of concrete structures (GB 50010—2010). Combined with the commonly used nonlinear structure analysis software ABAQUS, the conversion relation formula of the state quantity of constitutive relation was discussed. At the same time, improved concrete damage constitutive relation model was verified based on calculation results of ABAQUS software and some points for attention in application were pointed out.
