摘要
FRP筋是一种高性能的复合材料,与钢筋相比,FRP筋具有轻质、高的抗拉强度、耐腐蚀性好等特点。近年来,FRP筋代替钢筋或预应力钢筋被应用在混凝土结构中以提高耐久性成为一种趋势。文章对FRP筋增强混凝土梁、柱受力性能的研究现状进行了相关的介绍,并提出有待进一步深入研究的相关问题。
Fiber-reinforced polymer （FRP） bar is a kind of high-performance composite material. Compared to steels, FRP bars have the characteristics of light weight, high tensile strengthen, and excellent corrosion resistance.Recent years,FRP bars taking place of steels and prestress steels were applied broadly to concrete structure.Based on researching references,the researching actuality on mechanical behaviors of fiber-reinforced poly-strengthened concrete beams and columns was described.In the end of this paper,some problems that should be lucubrated were put forward.
