摘　　要：采用外加电流对混凝土压弯构件中的钢筋进行了快速锈蚀试验，通过钢筋锈蚀混凝土压弯构件在水平反复荷载作用下的试验研究，探讨钢筋锈蚀程度对混凝土压弯构件的承载力、刚度、延性、耗能能力等的影响，给出了锈蚀构件的滞回曲线和骨架曲线。Accelerated corrosion tests are carried out for reinforcing steels embedded in concrete by electrochemical method. Reinforced concrete members with flexural and compressive axial loads are put to experiments and analyzed under repeated horizontal loading. Through experiments the influence of reinforcement corrosion on the bearing capacity, stiffness, ductility and energy dissipation of the members are discussed. Hysteretic and skeleton curve for the corrosion members are obtained.
