摘　　要：为了研究钢筋外裹BFRP布后混凝土梁的抗弯承载力、延性系数、耗能能力及刚度,开展了钢筋混凝土梁抗弯试验.试验结果表明:与普通钢筋混凝土梁相比,钢筋外裹BFRP布后,梁的抗弯承载力、延性系数、耗能能力和刚度都有所提高.不同直径钢筋,梁的抗弯承载力、延性系数、耗能能力和刚度等提高程度不同.通过钢筋外裹纤维布的方法,能够有效地提高构件的承载力和抵抗变形能力,改善构件的抗震性能.提高了构件的耐久性,延长了建筑物的使用寿命.In order to study the flexural capacity, ductility coefficient, energy dissipation capacity and stiffness of concrete beams coated with BFRP,some experimental were carried out. The results show that compared with ordinary reinforced concrete beams, the flexural capacity, ductility coefficient, energy dissipation capacity and stiffness of the beams are improved after the reinforcement is wrapped with BFRP. The research results show that the fiber cloth method can effectively improve the bearing capacity and deformation resistance of the members, improve the seismic performance of the members, and is conducive to seismic resistance. Thus, the durability of the components is improved and the service life of the building is prolonged.
