FRP筋混凝土梁抗剪性能的研究进展

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。

STATE-OF-THE-ART ON SHEAR BEHAVIORS OF CONCRETE BEAMS WITH FRP TENDONS

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.
