随着纤维增强复合材料(Fiber Reinforced Polymer, FRP)在既有建筑结构加固领域的广泛应用,工程实践中对其加固特性愈发重视。本文综述了纤维增强复合材料(FRP)与混凝土粘结界面抗剪性能的研究进展。详细讨论了影响界面抗剪性能的各种因素,包括混凝土强度、FRP粘结长度、粘结宽度、粘结厚度及其弹性模量等。此外,本文介绍了灰色关联理论在分析界面粘结强度影响因素中的应用,通过建立试验数据库和关联度计算,确定了各参数对极限承载力的影响程度。最后,对现有的FRP-混凝土界面粘结强度模型进行了讨论,指出当前模型在预测实际工程中界面性能方面的局限性,并强调了考虑混凝土老化、损伤和钢筋锈蚀等因素的重要性。本研究为FRP加固混凝土结构的工程应用提供了科学的理论依据,并为未来研究指明了方向。The widespread application of Fiber Reinforced Polymer (FRP) sheets in the reinforcement of existing building structures has led to increased emphasis on their reinforcing characteristics. This paper reviews the research progress on the shear performance of the bond interface between FRP and concrete. Various factors influencing the interface shear performance are discussed in detail, including concrete strength, FRP bond length, bond width, bond thickness, and elastic modulus. Additionally, the application of Grey Relational Analysis (GRA) in evaluating the influential factors of bond strength is introduced. Through the establishment of an experimental database and correlation degree calculations, the impact of each parameter on ultimate bearing capacity is determined. Finally, the existing bond strength models for the FRP-concrete interface are discussed, highlighting the limitations of current models in predicting interface performance in practical engineering scenarios. The importance of considering factors such as concrete aging, damage, and reinforcement corrosion is emphasized. This s
