摘　　要：通过对锈蚀钢筋混凝土柱进行反复加载试验,分析反复加载下,不同锈蚀率锈蚀试件的滞回特性、承载力和延性的退化规律。结果表明:随着锈蚀率的增加,试件滞回曲线的丰满程度逐渐减小,屈服荷载、极限荷载以及延性均有不同程度的降低。Through the cyclic test of reinforced concrete column under different axial compression ratio, the effect of corrosion degree on hysteretic behavior, capacity and ductility is analysed. The test shows that as corrosion degree increases, the fullness of hysteretic curve of specimen is decreased gradually, yield load, limit load and ductility are lowered to different extent.

关 键 词：钢筋锈蚀 反复荷载 滞回曲线 承载力 延性
