摘　　要：根据提出的加固材料强度系数,并基于试验数据分析,分别提出了粘贴碳纤维布和粘贴钢板加固钢筋混凝土梁的抗弯承载力提高系数计算公式。研究结果表明,粘贴钢板比粘贴碳纤维布对梁的抗弯承载力有更好的加固效果。This paper proposes the flexural capacity formula of reinforced concrete beams strengthened with CFRP or steel plate based on the material strength factor and the experimental data. The research results show that the beam strengthened with steel plate has better strengthening effect in the flexural capacity than that with CFRP.
