摘　　要：以地震损伤钢筋混凝土梁为研究对象,重点研究损伤、加固后的钢筋混凝土梁的抗弯、抗震性能及加固措施,首先对试件进行损伤试验;然后对损伤试件进行碳纤维加固和钢板加固,试验和数值分析加固试件的抗震性能。试件变化参数为纵向钢筋配筋率、加固方式等参数,对比分析加固前后试件的受力性能与变形特征,并对不同加固方案的效果进行分析比较。为我国建筑抗震设计规范和混凝土结构加固规范的修订提供试验和理论参考。The earthquake damaged concrete beams were studied in this paper,the researchers focused on flexural, earthquake resistance and reinforcement methods of reinforced concrete beams after reinforcement, at frist, the damage test of the specimens was done;then the damaged specimens were reinforced with steel and carbon fiber, the seismic performance of specimens was analyzed by experiment and numerical simulation. The longitudinal reinforcement ratio and reinforcement method is as specimen parameters, mechanical properties and deformation characteristics of specimens were analyzed before and after reinforcement, and compared with the influence of different reinforcement. Providing the experimental and theoretical reference for revision of the specification for the code for seismic design of buildings and strengthening of concrete structure in China.
