FRP加固混凝土结构的最新研究进展

Research Progress on FRP Reinforced Concrete Structure

针对钢筋混凝土结构中因损伤影响结构安全的问题,国内外学者开展了关于FRP加固混凝土性能的广泛研究。分析总结了FRP外贴加固混凝土、FRP筋增强混凝土结构的现有技术水平、FRP索在桥梁中的应用现状以及FRP加固材料树脂基体的现状,并阐述关于FRP在温度、湿度、干湿循环、化学侵蚀、自然老化等各种环境条件下耐久性的研究进展,指出FRP在我国将有广阔的市场和应用前景。

With respect to the problem of influence of structural safety due to damage in the reinforced concrete structure, scholars both at home and abroad had conducted extensive researches on the performance of FRP reinforced con- crete. The state of the art of covering of FRP with reinforced concrete and FRP reinforced concrete structure, the present situation of application of FRP cables in bridges as well as present situation of resin matrix of FRP reinforcing material were analyzed and summarized, and advances in researches on the durability of FRP under various environmental conditions in terms of temperature, humidity, dry and wet circulation, chemical attack, natural aging, etc, were described. It was pointed out that FRP would have broad market and application prospect in our country.
