摘　　要：钢筋锈蚀是影响混凝土结构耐久性的首要因素,而纤维增强聚合物筋(FRP筋)是一种具有高强、轻质、耐腐蚀、耐疲劳等特点的新型复合材料,用其代替钢筋是解决钢筋锈蚀问题的新途径之一。本文对新型FRP筋的基本性能及特点进行分析,并介绍了国内外有关FRP筋的最新研究进展。Steel reinforcement corrosion is the chief influencing factor of durability of concrete struc- tures. Fiber reinforced polymer（FRP） bars, a new compound material with high tensile strength, light weight, strong resistance to corrosion and fatigue, is a new solution to the corrosion of steel reinforce- ment in concrete if replaced by FRP bars. This paper discusses the basic behaviors and features of the FRP bars and describes the latest research and application progress of the FRP bars reinforced con- crete.
