摘要
纤维增强复合材料(FRP)具有耐腐蚀、质量轻、强度高、延性好、施工方便等优点,主要应用于土木工程维修与加固领域。对FRP-混凝土组合柱力学性能研究进展进行综述,分析影响FRP约束混凝土柱和FRP约束钢管混凝土柱的承载力、变形、应力-应变关系等的主要因素,指出已有研究存在的不足,展望FRP未来主要研究方向,为深入开展FRP-混凝土组合柱的性能研究提供参考。
Fiber reinforced polymer(FRP) has advantages of non-corrodibility, light weight, high strength, good durability, and convenient construction, which may adapt to the repair and reinforcement of civil engineering structure. After briefly reviewing the research progress of mechanical properties FRP-concrete composite columns, the main factors of the load-carrying capacity, deformation and stress-strain relationship of FRP confined concrete column and FRP confmed concrete filled steel tubes are described, the deficiency of the existing studies are pointed out, and the future study direction of FRP are prospected, which provides reference for developing the study of FRP-concrete composite column.
