摘  要:HFRP加固钢筋混凝土结构的方法在实际工程已经逐渐被应用。本文采用13根梁作为试验基础,分别对黏贴不同纤维材料的钢筋混凝土梁进行了破坏性试验。结果表明:采用混凝土应力一应变全曲线进行推导的公式能够真实的表现混凝土材料的这个破坏过程;加固钢筋混凝土梁的极限承载力随纤维材料加固层数增多而增大,但承载力非线性的增长;加固后钢筋混凝土梁能够减小极限状态的最大裂缝宽度,而且裂缝的均匀性更好。The approach to reinforce concrete structure with HFRP in practical engineering has been applied gradually. This paper used 13 beams as a test base to respectively paste different fiber materials and to damage them. The results showed that the formula of concrete stress-strain curve could be used to derive the destroyed process, the ultimate bearing capacity of reinforced concrete beam was increasing with layers of fiber increasing, but it was not linear and the reinforced concrete beam strengthened later could reduce into the maximum crack width and the uniformity of crack was better then before.
