摘　　要：通过采用两点对称集中加载的方法,对4根玄武岩纤维布加固的钢筋混凝土梁和1根未加固梁的正截面承载力的对比试验,观测并分析了试验梁发生破坏的全过程、应变分布情况、承载力和延性,并分析了玄武岩纤维布粘贴层数、粘贴锚固方式对加固效果的影响.试验证明玄武岩纤维布加固钢筋混凝土梁符合加固设计规范要求.The static test is carried out on four RC beams strengthened by BFRP sheets and one common RC beam for comparison by the way of two-point symmetric localized loading. It observed and analyzed the whole failure process, the distributed characteristic of strains, carrying capacity and ductility, and analyzed the influence of the layer number of the BF and the way of gluing. Experiments showed reinforced concrete beam strengthened with BFRP can satisty reinforced design standards.
