[摘要] 制作了5个150mm x150mm×450mm的钢筋混凝土棱柱体试件，采用外加直流电的方式对其中4个试件内的箍筋进行了快速锈蚀，并对试件进行了轴心受压试验研究。通过试验测得了锈蚀箍筋约束混凝土的应力-应变曲线，分析了箍筋锈蚀量对约束混凝土应力-应变曲线的影响，并分析了箍筋锈蚀对约束混凝土试件的承载力和延性的影响。

Abstract: One group of 5 steel reinforced concrete prisms specimens with dimensions of 150mmX150mm×450mm were produced. Stirrups of 4 specimens were subjected to an accelerated galvanic corrosion process and all of these specimens were tested under uniaxial compressive loading. Based on the experimental study, stress-strain curves of concrete confmed by corroded stirrups were measured. Besides, the influence of stirrup corrosion rate on stress-strain curve, strength and ductility were analyzed.
Keywords: corroded stinups; confmed concrete; stress-strain curve; strength; ductility
