| 摘 要： | 进行了28个纤维聚合物(FRP)筋拔出粘结试验,试验变量为FRP筋种类、FRP筋直径、混凝土强度和粘结长度,拔出试验记录了拔出荷载、FRP筋加载端滑移、破坏现象。FRP筋破坏形式是表面脱落和筋断裂,而混凝土未出现明显破坏。随着FRP筋的种类、直径、粘结长度不同,粘结强度变化范围是7.96~41.80MPa,粘结强度随着粘结长度、直径增加而减少,与混凝土强度无关。

| Abstract: | This paper presents the results of 28 pullout bond tests on fiber reinforced polymer FRP bars embedded in concrete. The pullout test variables involve types of FRP bars, diameter of FRP bars , concrete strength , and bond lengths . The applied load and slip at the loaded ends were measured at each load level . The failure modes were recorded in the pullout test. It was found that the ribs of FRP bars were sheared off and FRP bars were fracture. The bond strength of FRP bars decreased as bond length and bar diameter increased, the bond strength were 7.96～41.80 MPa. The concrete strength had no effect on the bond strength of FRP bars . |
