纤维增强复合材料(FRP)加固砌体结构的性能研究进展

State-of-the-art review on performance of masonry structure strengthened by fiber reinforced plastics

纤维增强复合材料(FRP)以其高强轻质、耐腐蚀、耐疲劳、施工便捷和不增加构件尺寸等诸多优点备受土木工程界的关注。本文首先简要介绍了FRP片材加固砌体结构技术,FRP片材的性能特点,以及FRP加固法的技术优势。然后,对国内外FRP加固修复砌体结构的研究与应用进行了系统的总结与回顾,评述了国内外关于此项技术的试验研究的主要内容及试验结论。最后,指出了此项技术在砌体结构应用与研究过程中存在的一些主要问题。

Fiber reinforced plastics(FRP) has attention in civil engineering due to their unique properties,such as high ratio of strength to weight,good resistance to corrosion and fatigue and convenient to construction.Firstly,this paper simply introduces the reinforcement of masonry structure wht FRP laminates,the character of FRP laminates,the advantage of the reinforcement of masonry with FRP lamimates.Secondly the paper alao summarizes and reviews the research and use of the masonry structure strengthened and repaired with FRP overseas.And the author generally describes the content and conduction of experimental study about it too.Finally,some problems consisting in the course of research and applications are presented.
