A new technique for strengthening concrete structures - near-surface mounted FRP reinforcement

Abstract

嵌入式 (NSM)加固法是FRP材料加固混凝土结构的一种新的应用形式 ,较外贴加固在某些方面具有明显优势。目前该技术在国内的研究应用尚属空白 ,对在该领域已有的国外文献从材料、试验研究、粘结性能和设计方法等几个方面进行了总结 ,可为国内今后开展相关的研究和应用提供借鉴和参考。 Near-surface mounted (NSM) FRP reinforcement is emerging as a promising technique for the strengthening of concrete structures, as it offers some real practical advantages over externally bonded FRP reinforcement. This paper presents a state-of-the-art review of the existing international research on NSM reinforcement.Topics covered include materials, bond behaviour, flexural strengthening tests and design recommendations. It provides a basis for further research and application in China.
