碳纤维布加固箍筋锈蚀RC梁抗剪性能试验研究

为研究碳纤维布加固3种不同锈蚀率下钢筋混凝土梁斜截面受力性能,设计并制作了6根具有相同混凝土强度等级、相同配筋率以及相同尺寸的混凝土梁,并将这6根梁分为试验组和对照组,用碳纤维布对试验组的3根梁进行加固,对照组的3根梁不做加固处理,并对实验结果进行了分析比较,得出了一些有意义的结论。

Experimental research on shear capacity of RC beams with corroded stirrups strengthened by CFRP

In this paper, the shear behavior of reinforced concrete beams with corroded stirrups strengthened with CFRP is researched. The stir- rups of beams were in three different corrosion degrees. In the experiment, six beams with the same size, concrete strength grade, ratio of rein- forcement were made. All the beams were divided into two groups： the experimental group and the control group. CFRP was used to repair the beams in the experimental group while the beams in the control group were not repaired, and the experimental results were analyzed and com- pared, finally collects some beneficial conclusions.
