复杂应力状态下高强混凝土的损伤本构理论及应用

Damage constitutive theory of high strength concrete in complex stress state and its application

基于高强砼轴向压缩试验测定的压缩应力与应变全曲线及其特征点相对应参数，建立了压缩损伤本构模型；

Based on the stress and strain diagram and its characteristic point of experiments on compression state, this paper sets up the damage constitutive model of high strength concrete in compression state. By theoretical analyses, this paper presents the damage constitutive models of high strength concrete in two directional stress state and three directional stress state in all principal directions and the calculation methods of non linear damage finite element.
