摘　　要：针对地震损伤钢筋混凝土结构,采用静力加载试验的方法,对不同配筋率的钢筋混凝土梁和不同轴压比作用下的柱进行了水平低周反复荷载作用下加载试验,研究采用粘贴钢板、粘贴碳纤维布等方法加固修复损伤钢筋混凝土结构的效果。同时从安全可靠性、施工方便性和经济适用性方面对各种加固方法特点进行总结,通过对地震损伤钢筋混凝土结构采用不同的加固方法进行试验研究,为实际地震损伤建筑加固修复工程及抗震加固工程提供有价值的参考和建议,为抗震鉴定、加固修复标准修订提供理论依据。Reinforcement and repair methods of earthquake damaged concrete structures was studied in this paper.RC beams with different reinforcement ratio and RC columns with different axial compression ratio were experimented under horizontal low cyclic loading.The effect of pasting armor plate or carbon cloth on damaged concrete structures was analysed.The features of different reinforcement and repair methods were summed up in the paper.Practical suggestions were offered for reinforcement and repair projects.theory evidence was also provieded for revising standard of reinforcement and repair.
