无机胶粘贴碳纤维布抗弯加固钢筋混凝土梁延性试验研究

Experimental Study on Ductility of RC Beams Strengthened in Flexure with Carbon Fiber Sheet by Inorganic Paste

对9根粘贴碳纤维布的钢筋混凝土梁进行试验研究,试验结果表明,随着配筋率的提高,试验梁的延性明显下降;对于无机胶粘贴碳纤维布加固梁,试验梁的延性随着碳纤维层数的增多而下降,无机胶粘贴碳纤维布加固梁的延性比有机胶粘贴碳纤维布加固梁的延性有所下降。

Experiment on nine RC beams strengthened with different number of carbon fiber sheet shows that with the increase of reinforcement ratio, the ductility of test beams will reduce.For beams strengthened with CFS by inorganic paste, the ductility of test beams reduce with the increase of layers of CFS and is lower than the ductility of beams stengthened with CFS by epoxy adhesives.
