摘　　要：钢筋混凝土柱是混凝土结构中最重要的承重构件及抗侧力构件,尤其是滨海环境的混凝土结构,长期处于氯盐环境中的钢筋混凝土柱很容易出现外部混凝土性能劣化、内部钢筋锈蚀等问题。如不进行加固修复处理,将危及整个结构的安全。纤维网增强混凝土(TRC)作为一种新型纤维增强复合材料,应用于锈蚀钢筋混凝土柱的加固,不仅能够提高锈蚀钢筋混凝土柱的力学性能,而且能够有效阻止氯离子对构件的进一步侵蚀。对现阶段TRC加固锈蚀钢筋混凝土柱研究现状进行梳理,介绍了TRC加固锈蚀钢筋混凝土柱的受压性能和低周反复加载下的抗震性能,并提出了后续研究亟待解决的问题。Reinforced concrete columns are the most important load-bearing and lateral force resistant members in concrete structures,especially in coastal concrete structures.Reinforced concrete columns that have been in chloride environment for a long time are prone to external concrete performance degradation,internal reinforcement corrosion and other problems.If reinforcement and repair are not carried out,the safety of the whole structure will be endangered.As a new type of fiber reinforced composite material,textile reinforced concrete(TRC)applied to the reinforcement of corroded reinforced concrete columns can not only improve the mechanical properties of corroded reinforced concrete columns,but also effectively prevent the further corrosion of chloride ions on members.This paper combs the current research status of corroded reinforced concrete columns strengthened by TRC,introduces the compression performance and seismic performance of corroded reinforced concrete columns strengthened by TRC under low cycle repeated loading,and puts forward the problems that need to be solved in the follow-up research.
