| 摘 要： | 本文提出了一种用碳纤维布提高钢筋混凝土框架结构梁柱端部截面受弯承载力的方法,并通过3个钢筋混凝土梁-柱-节点构件(其中的2个用这种方法进行了加固)的低周反复加载试验,对这种加固方法的加固效果进行了验证。试验结果表明,这种加固方法明显提高了梁、柱截面的受弯承载力,加固构件的延性和耗能能力也得到改善。

| Abstract: | In this paper, a strengthening method to increase the bend strength of the end sections of the beams and columns in RC frame joints by strengthening with CFRPs is proposed. To investigate the performance of the strengthened specimen, the reversed cyclic static loading tests of three beam-column joints of RC frames, two of which are strengthened by this method, are carried out. The test result shows that the bend strength of the end sections of the beams and columns is increased, and the ductility and the capacity of energy dissipation of the strengthened specimen are improved also. |
