摘要
纤维增强复合材料(FRP)是一种高性能新型结构材料,近年来在混凝土结构加固修复领域中得到了广泛的应用。综述了国内外学者对FRP加固混凝土的研究现状,介绍了FRP材料的分类以及FRP片材的优点,总结了基于断裂力学的6种FRP与混凝土界面黏结滑移模型,在此基础上,归纳总结了FRP加固混凝土中存在的不足,并对未来FRP加固混凝土研究方向进行了展望。
In recent years,as a new type of structural material with high performance,fiber reinforced polymer(FRP)has been widely used in the field of reinforcement and repair of concrete structures or components.It summarizes the research status of FRP reinforced concrete at home and abroad,introduces the classification of FRP materials,discusses the advantages of FRP sheets from mechanical properties,chemical stability and engineering applicability.In addition,the bond-slip model of FRP-concrete interface based on fracture mechanics is summarized.Finally,some problems and suggestions are put forward for the research of FRP reinforced concrete.
