摘要
对混凝土结构中的钢筋新型代用材料FRP筋在周围不同环境介质中的粘结锚固性能进行了试验研究 .通过对 36个FRP筋混凝土和钢筋混凝土所进行的立方体试件中心拔出试验研究 ,得出了FRP筋在混凝土、水泥浆和环氧树脂中的粘结锚固性能 .试验结果表明 :FRP筋在周围不同介质中的粘结锚固性能与钢筋在相应介质中的粘结锚固性能相似 ;螺纹FRP筋的粘结锚固性能要明显高于光面FRP筋 .
In this paper, the bond characteristics of FRP reinforcing bars in different environmental media are studied. The media consist of concrete,cement grout and epoxy. The pullout and bond properties are found out through thirty six pullout tests.The results of the study show that glass fiber rod bond strength in different media is similar to that of steel bars in corresponding media,and that the bond strength of helical FRP reinforcing bars is higher than that of plain FRP reinforcing bars.
