摘要/Abstract

摘要： 混凝土梁(RC梁)作为结构体系中的主要受力构件之一,常因各种原因出现劣损影响到结构安全。FRP材料因其具有轻质、高强、耐腐蚀等特性,已被广泛应用于RC梁的加固工程中。目前,FRP加固RC梁的研究较为深入。本文综述了国内外学者关于FRP加固RC梁的静力性能以及抗火性、抗冲击性的研究现状,分析了现阶段研究存在的问题,提出了对未来研究方向的建议。

关键词: FRP, RC梁, 静力性能, 抗火性, 抗冲击性

Abstract: As one of the main force-receiving members in reinforced concrete structure system, reinforced concrete (RC) beams often break or affect structural safety because of various reasons. As a new type of structural material, FRP has been widely used in practical RC beams reinforcement engineering with its light-weight, high-strength and corrosion resistance. At present, the research on FRP reinforced RC beams is more in-depth. This paper has compiled the research status of the static performance, fire resistance and impact resistance of FRP-strengthened RC beams by domestic and foreign scholars, analyzes the problems existing in the current research, and puts forward suggestions for future research directions.

Key words: FRP, RC beam, static performance, fire resistance, impact resistance
