[摘要]對《混凝土結(jié)構(gòu)設(shè)計規(guī)范》(GB 50010—2010)中混凝土損傷本構(gòu)關(guān)系模型進行局部改進。進而結(jié)合常用的結(jié)構(gòu)非線性分析軟件ABAQUS,討論了本構(gòu)關(guān)系狀態(tài)量的換算關(guān)系式,同時基于ABAQUS軟件的計算結(jié)果對改進的混凝土損傷本構(gòu)關(guān)系模型進行了驗證,并指出了其應(yīng)用過程中的若干注意點。

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.
Keywords:concrete; damage; plasticity; calculation
