摘　　要：使用粘贴钢板法对锈蚀钢筋混凝土矩形截面梁进行加固研究.基于ABAQUS有限元分析软件,采用粘贴钢板对一根锈蚀率为8%的钢筋混凝土梁正截面进行加固.对梁加固后,钢筋混凝土梁的承载力明显提高;梁的屈服挠度变化不明显.有限元分析结果与理论分析结果吻合较好,可以为粘贴钢板法加固钢筋混凝土梁提供鉴定评估.Use bonding steel plate method for reinforcement of corroded reinforced concrete beam.Based on the finite element analysis software ABAQUS,the corroded reinforced concrete beam was rainforced by steel plate,the corrosion rate of the reinforced concrete beam is8%.After reinforcement,the bearing capacity of the reinforced concrete beam increases obviously,and yield deflection has no significant change.The numerical analysis results agree well with the theoretical result,which is expected to provide advice to appraisal and evaluation of bonding steel plate method for reinforcement of reinforced concrete.
