[摘要] ABAQUS中的混凝土塑性损伤模型用于模拟低围压情况下反复荷载作用时的混凝土力学行为，引入损伤因子，描述反复荷载作用下混凝土刚度的变化。主要介绍该模型的理论，同时结合《混凝土结构设计规范》中建议的混凝土单轴本构关系，给出各参数的确定方法。

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.
