Notes:
The damage constitutive relationship is a key problem to nonlinear analysis of structuralmembers. It is much more necessary to study systematically related damage constitutive relationshipof steel reinforced concrete (SRC) members because of their peculiarity. Based on the experimentalphenomena analysis and damage theory, the mesoscopic failure mechanism of concrete as well as theinterface of shaped steel and concrete is analyzed. At the same time, their mesoscopic damage modelsand corresponding assumptions of the models are established by considering material failurecharacteristics. Subsequently, the mechanism of the models is analyzed, which indicates that they fitto simulate failure process of the materials. According to the models, the related damage constitutiverelationship for SRC members is deduced by principle of energy and force balance. Combined withcorresponding experimental study, it is shown that the constitutive relationship presented isreasonable and practicable, so it facilitates SRC member nonlinear analysis
