| 摘 要： | 通过5个芳纶布(AFRP)加固钢筋混凝土框架节点和2个未加固节点的抗震性能试验,研究了加固方式对抗震性能的影响、AFRP布的应变变化规律。研究结果表明,采用AFRP加固后的梁柱节点,极限承载力和抗震性能得到了显著改善,核心区域采用X型粘贴纤维布加固方式、用压条来锚固X型粘布是一种非常有效的锚固方式。

| Abstract: | Five steel reinforced concrete beam-column joints strengthened with AFRP sheets and two unstrengthened joints are tested for comparing their influences on seismic performances.Based on the experimental results,the changing law of AFRP sheet strains are analyzed,and a new anchoring method is presented.It is found that the ultimate strength and seismic behavior of the joints strengthened with AFRP are improved remarkably;using X type AFRP sheets anchor in the joint core area is an effective anchorage method for seismic retrofitting. |
