摘　　要：钢筋锈蚀是引起在役结构抗震性能降低的主要原因。想要正确评估锈蚀结构在地震作用下的损伤,则需要以锈蚀钢筋混凝土构件为研究对象,研究其抗震性能的降低情况。因此,采用外加电流加速混凝土中钢筋锈蚀的方法制作4个锈蚀钢筋混凝土试件,对其中3个锈蚀钢筋混凝土试件进行CFRP加固处理,通过水平往复荷载下的试验,研究CFRP加固对锈蚀试件的承载力、延性和滞回性能的影响。Corrosion of steel bar is the main reason that makes the aseismic performance of RC structure degradation.To evaluate the damage of structure under the action of earthquake correctly,corroded reinforced concrete member should be taken as an object,and degradation of its aseismic performance is studied.So we produced four corroded reinforced concrete specimen through the electrochemical corrosion method.And four corroded reinforced concrete specimens are peoduced through the electro chemical corrosion method.Then aseismic performance of CFRP strengthening corroded reinforced concrete column is studied through the experiment of the horizontal reciprocating loding,such as bearing capacity,ductility and hysteretic behaviorm,and so on.
