FRP加固损伤混凝土结构研究综述

REVIEW OF FRP REINFORCED DAMAGED CONCRETE STRUCTURE

FRP加固混凝土结构应用越来越广泛,在实际工程应用中,大多数混凝土结构都是在预加载下工作,未损伤混凝土结构相对较少,而现有的研究大多数是基于未损伤混凝土结构,因此,对FRP加固损伤混凝土结构的研究是FRP加固领域的重要课题。论文对国内外FRP加固损伤混凝土柱、梁及抗震和抗火的研究进行了分析和概括,提出了近期需要研究的问题,为相关研究和工程应用提供参考。

Fiber Reinforced Polymer （FRP） has been increasingly widely used to strengthen concrete structure. In the practical engineering applications, most of the concrete structures are working under preloading, but the majority of the existing research concerns about the un-damaged concrete structure. Thus, the study on strengthening damaged concrete structures is an important topic at home and abroad. In this paper, the column, beam, seismic and anti-fire of concrete structures strengthened with FRP reinforcement are analyzed and summarized, and the topics that need to be solved in the future are presented. This can provide some reference for corresponding research and engineering application.
