摘　　要：首先对 4个十字形混凝土梁板柱节点进行破损加载 ,模拟中小地震中的损伤 ,然后进行灌缝修复和粘贴碳纤维加固。加固试件和对比试件的低周反复荷载试验结果表明 ,采用的加固修复方法非常有效 ,受损试件加固后的抗震性能要优于对比试件。In this paper the aseismic behaviour of five column beam slab assemblies were studied under low cycle reversed load simulating the medium and small earthquake loads.First four of them were damaged to different degrees then their cracks were filled up and these specimens were strengthened by CFRP.The experiment showed positive result of this strengthening method.
