摘　　要：进行了FRP筋与混凝土粘结性能的拉拔试验,试件的破坏形式为FRP筋滑移拔出及FRP筋断裂。试验结果表明,随着FRP筋表面加肋,锚固长度减少,混凝土强度提高,FRP筋与混凝土的平均粘结强度都有了提高。同时,对带肋FRP筋与光圆FRP筋的粘结滑移本构模型进行了分析。The article introduces the drawing test of FRP bar and concrete bond performance.The destroying type of test piece is the slippage and pulling out of FRP bar as well as the break of FRP bar.The test result shows that with the surface ribbing of FRP bar,decrement of anchorage length and improvement of concrete strength,the average bond strength of FRP bar and concrete improves.Also the article analyzes the bond slip constitutive model of ribbed FRP bar and plain bar.
