摘　　要：纤维增强复合材料(Fiber Reinforced Polymer简称FRP)是一种轻质、高强、耐久性好的复合材料。大量的试验研究表明,不论是FRP布、FRP板、FRP网还是FRP片材加固砌体结构,都能有效提高砌体结构的抗剪承载力,加固后墙体延性、变形能力等抗震性能得到明显改善,刚度退化较未加固砌体明显减缓,抗震耗能能力增强。本文分析了现有的部分文献成果,归纳总结了FRP加固砌体墙体承载力实用设计计算公式。Fiber reinforced polymer(FRP) is high-performance composite material,which is lightweight, high strength, convenient construction. Experimental studies show that FRP, including FRP clothes, FRP gauzes and FRP sheet, can effectively enhance the shearing capacity of masonry. Seismic performances like ductile ability and deformability of reinforced masonries can be significantly improved either. Compared to the unreinforced masonry, its stiffness degradation slows down significantly, but seismic resistance and energy dissipation capacity are enhanced. The existing literatures are analyzed, concluding some practical formulas with regard to bearing capacity of the reinforced masonry structures by FRP.
