This paper selected project group made 2 reinforced concrete cantilever beam,based on ABAQUS made lower cyclic nonlinear analy-sis,gained the stress and deformation characteristics of reinforced concrete member,and based on correction Park-Ang damage model,calculated its damage index,through the comparison of simulation results with experimental results,indicated that the damage index of reasonable numerical simulation and damage model calculation component,could better reaction of damage situation of reinforced concrete members.%选取项目组制作的2根钢筋混凝土悬臂梁，基于ABAQUS进行了低周往复非线性分析，得到钢筋混凝土构件的受力和变形特点，并基于修正的Park-Ang损伤模型，计算其损伤指数，通过将模拟结果与试验结果进行对比，说明利用合理数值模型与损伤模型计算构件的损伤指数，可以很好的反映钢筋混凝土构件的损伤情况。
