表层嵌贴FRP-混凝土黏结加固研究进展

摘要

Near-surface mounted(NSM)fiber-reinforced polymer(FRP)reinforcement is one of the latest and most promising strength-ening techniques for reinforced concrete(RC)structures.Research on this topic mainly focused on the bonding mechanism and the flexural strengthening.The paper presents bond mechanics of NSM FRP bars/strips to concrete including the bond test methods ,effect of test vari-ables,bond failure modes,analytical modeling,local bond shear stress-slip relationship.It provides a critical review of existing research in this area,identifies gaps of knowledge,and outlines directions for further research.%表层嵌贴FRP修复加固混凝土结构是一种富有前景的新型技术，目前该技术领域的研究主要集中在黏结机理和抗弯加固两方面。论述表层嵌贴FRP-混凝土的试验方法、主要控制参数、破坏模式、黏结机理、界面黏结滑移本构关系等。最后，对目前国内外表层嵌贴FRP-混凝土黏结性能的研究现状进行探讨，希望为表层嵌贴FRP加固技术的进一步研究发展提供方向。
