摘要
通过3个混凝土框架节点的低周反复加载试验,研究了碳纤维布加固方法对节点核心区抗剪性能的改善效果。试验结果表明:碳纤维布能够有效地增强节点核心区的抗剪承载力,提高节点的承载力与延性,从而显著改善梁柱节点组合体的抗震性能。
To evaluate the shear improvement of beam-colmnn joints strengthened by CFRP sheets, three beam-column joints were tested under quasi-static cycle load. It was verified that the shear capacity of joint core could be effectively upgraded by CFRP sheets and the seismic behavior of beam-column joints is also improved significantly as the result of increasing of load-carrying capacity and ductility.
