摘要
混凝土平面框架节点核心区不存在直交梁的影响,可以应用碳纤维布直接进行加固,以增强地震作用下节点核心区的抗剪承载力。根据足尺混凝土框架节点低周反复加载试验结果,对碳纤维布的增强机理进行了分析和讨论,并在此基础上提出了实用的加固计算公式。
CFRP sheets can directly strengthen cores of beam-column joints in one-way frames to improve their shear behavior under seismic load. Based on the experiment results of quasi-static cycle load test of full-scale RC beamcolumn joints, in this paper the shear resistance mechanism of beam-column joints strengthened by the CFRP sheets is not only analyzed but a practical design method is provided for engineering application.
