摘要(Abstract):

制作了5个150mm×150mm×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。
One group of 5 steel reinforced concrete prisms specimens with dimensions of 150mm×150mm×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 confined by corroded stirrups were measured.Besides,the influence of stirrup corrosion rate on stress-strain curve,strength and ductility were analyzed.
