［摘要］介绍了体外交叉钢筋加固框架节点的做法，并通过3个T形钢筋混凝土框架节点试件的低周反复加载试验，对提出的加固做法进行了检验。试验研究结果表明：所采用的加固方法能够有效增强节点核心区的抗剪性能，改变节点的剪切破坏模式；对于节点组合体滞回特性、延性性能以及承载力等抗震性能的改善效果比较明显。

Abstract:Reinforcement method of frame beam-column joints with external crossed reinforcing steel was introduced through 3 T-shape reinforced concrete joints subjected to cyclic loading, and the method had been verified. The result indicates that the new reinforcement method can improve anti-shearing performance of the core area effectively and change the shearing failure pattern of the joint. Otherwise, seismic performance, such as hysteretic property, ductility performance and bearing capacity of the joint, are improved obviously.
Keywords:frame beam-column joints; cyclic loading; reinforcement; experimental study
