摘　　要：为对比研究钢筋混凝土框架节点区梁端加固前后及采用不同加固方法加固后的性能,共进行了6个梁柱中节点模型试件的试验研究,对加固前后以及不同加固方法加固的试件的试验结果进行对比,得到框架节点区加固的有益结论,可为实际工程加固提供参考。Six isolated and simplified reinforced concrete （RC） beam-column joint specimens were tested in order to study the behavior of the RC frames＇ beam end zones before and after strengthening. Eventually, the rehabilitated specimens were retested under low cyclic loading, Suggestions for design, construction and for further research were presented based on the whole research.
