摘　　要：首先阐述传统加固方式的优缺点,进一步说明碳纤维加固方式的意义和优点。然后给出碳纤维加固过程中钢筋,受压区混凝土及碳纤维的本构模型,在此基础上给出具体的计算步骤,并研究不同结构不同碳纤维布下结构件的极限弯矩和破坏模式。结果表明:碳纤维布的面积对结构件的破坏模式具有显著的影响。This paper begins by describing the advantages and disadvantages of the traditional reinforcement methods,and further illustrates the significance of carbon fiber reinforcement and benefits.And then the constitutive models are given to the process of carbon fiber reinforced steel bars,the compression zone of concrete and carbon fiber.On this basis,the specific calculation steps is established and the relationship among the different structures and the limit bending moment and the failure mode of different structures.The results showed that the area of CFRP has a significant impact on the failure mode of structural members.
