纤维复合筋-混凝土梁研究概况

纤维增强聚合物(FRP)型材是一种具有耐腐蚀、适用性广、轻质高强等诸多优点的新型复合材料,将其与混凝土相结合,形成FRP-混凝土组合梁结构,以达到减轻混凝土结构自重,提高结构承载力的同时,解决钢筋易腐蚀、抗裂性差的问题,希望可以为新型混凝土结构发展做出一定贡献。

Fiber reinforced polymer(FRP)profile is a new type of composite material with many advantages,such as corrosion resistance,wide applicability,light weight and high strength.It is combined with concrete to form FRP-concrete composite beam structure,so as to reduce the self-weight of concrete structure and improve the bearing capacity of the structure.At the same time,the problems of corrosion and poor crack resistance of steel bar are solved.It is hoped that it can make some contribution to the development of new concrete structure.
