摘要:

与普通钢筋相比,FRP筋具有抗拉强度高、抗腐蚀性能优良、重量轻、弹模低等优点,较适用于特殊环境下的混凝土结构。但是FRP筋的横向强度很低,因此,关于FRP筋混凝土结构的抗剪性能是国内外工程领域非常关注的一个问题。本文分别介绍了国内外关于非预应力和预应力FRP筋混凝土结构抗剪性能研究的主要成果,并对今后拟开展的研究工作提出了建议。

Abstract:

Compare with ordinary steel rebars, FRP tendons have the characteristics of high tensile strength, noncorrosive, light weight and low elastics modulus, etc, which have been taken as an attractive alternative reinforcing material for steel to the corrosion problem However, FRP’s transverse strength is very low, studies on shear behaviors of concrete structures with FRP tendons have been emphasized in engineering structure field This paper briefly introduces the main progresses in the studies on shear behaviors from nonprestressed and prestressed concrete beams with FRP tendons Finally, advices for advanced research are proposed

Key words: FRP tendons, shear behaviors, concrete beam
