| 摘 要： | 基于高强混凝土的拉伸应力与应变全曲线及其特征点相对应参数，建立了拉伸损伤本构模型；通过理论分析提出了高强混凝土在二向与三向应力状态下拉、压两类损伤时的损伤耦合模型；根据混凝土结构总是拉裂破坏的事实，提出了用拉应变与损伤度双参量描述的损伤断裂准则，具有重要实用价值

| Abstract: | Based on the stress and strain diagram and its characteristic points of experiments on one directional tension, this paper sets up the damage constitutive model of high strength concrete in one directional tension state. By theoretical analysis, this paper presents the tension compression coupled damage constitutive model of high strength concrete in two directional stress state and three directional stress state. Based on the fact of tension fracture failure of concrete structure, this paper also presents the damage fracture criterion with tensions train and damage. |
