摘　　要：简要介绍了五个用碳纤维加固的混凝土低配箍梁板柱节点低周反复试验的情况 ,对试验结果进行了分析 ,发现加固后的节点极限承载力和抗震性能都有大幅度的提高 ,各项性能指标都达到并超过了我国现行抗震规范的要求 ,因此碳纤维加固混凝土节点技术是一个值得进一步深入研究的课题 .In this paper,five beam column slab subassemblies are tested under low frequency reversed load.The results are analyzed.It is found that after reinforcement the ultimate strength and aseismatic behavior of joints are greatly enhanced.Almost all the behaviors of strengthened joints exceed the requirement raised by current code.So such technique is a significant one which deserves further investigation.
