介绍了FRP的材料性能,FRP新的加固形式(嵌入式加固)与传统的FRP加固形式(外贴式加固)进行了对比。通过CFRP板加固(嵌入式)受损RC梁试验,发现其承载力有很大提升。对于陈和滕提出的外贴FRP与混凝土界面粘结公式(C-T公式)进行了改进,提出了适合于FRP嵌入式加固受损RC梁正截面承载力的计算方法,以期为FRP嵌入式加固法的进一步研究提供参考。
The material properties of FRP are introduced. The new reinforced FRP (embedded reinforcement) is compared with the traditional FRP reinforcement (external reinforcement). By CFRP board reinforcement (embedded) damaged RC beam test and found that the bearing capacity has greatly improved. The improvement of the bonding formula of FRP and concrete (CT formula) proposed by Chen and Teng was put forward. The calculation method of the normal section bearing capacity of RC beam damaged by FRP embedded reinforcement was put forward in order to provide the FRP embedded reinforcement method For further research to provide reference.
