摘要
通过对加固与未加固节点的加载对比试验,分析碳纤维布距离梁边的远近以及碳纤维布加固量的不同对梁柱节点负弯矩区加固效果的影响规律。试验结果表明:粘贴的碳纤维布离梁边越近,其加固效果越好;反之效果越差。碳纤维布粘贴的层数越多,加固效果越好。但是当粘贴层数大于3层时,梁的极限抗弯承载力增大不再明显。
By the comparison of the connection and reinforced connections ’ loading tests , this paper aims to analyse the different distance from the side of the beam to CFRP and the changing influence on the reinforcement effect of connection owning to different layers of CFRP sheets .The experimental results show that the closer distance from sticking CFRP to beam edge , the better the consolidation .Conversely , the effect is worse .The more layers of CFRP sheets, the more effect.But when the layer of the CFRP sheets is more than 3, the ultimate flexural resistance of the beam-to-column connection will not be obvious .
