（廣東省建筑設(shè)計研究院，廣州510010）[摘要] ABAQUS中的混凝土塑性損傷模型用于模擬低圍壓情況下反復(fù)荷載作用時的混凝土力學(xué)行為，引入損傷因子，描述反復(fù)荷載作用下混凝土剛度的變化。主要介紹該模型的理論，同時結(jié)合《混凝土結(jié)構(gòu)設(shè)計規(guī)范》中建議的混凝土單軸本構(gòu)關(guān)系，給出各參數(shù)的確定方法。

( The Arclutectural Design and Research Institute of Guangdong Province, Guangzhou 510010, China)Abstract: The concrete damaged plasticity model in ABAQUS can be used for simulating the behavior of concrete under low confming pressures. The damage variable is defined for simulating the stiffness degradation of concrete under cyclic loading. The theory of the model was introduced and a way used to determine the parameters of the model was provided, using the stress-strain relations from Code for design, of concrete structures.
Keywords: concrete; plastic damage; stiffness degradation; ABAQUS
