通过对钢筋混凝土构件加固设计常采用的粘钢、粘碳纤维布方案中遇到的问题进行阐述,从粘钢、粘贴碳纤维布加固设计中的最大加固量、最小加固量及加固量计算等3个方面进行探讨,指出了在已知构件截面及新的计算配筋的情况下,即可快速计算粘钢、粘碳纤维布加固方法的加固量。经过对规范公式的简化,给出了粘钢、粘碳布粘贴量计算中的一些参数,利用这些参数可快速计算出构件粘钢、粘碳纤维布的具体加固量,对实际工作具有指导意义。

This paper expounds the problems encountered in the reinforcement design of reinforced concrete members by sticking steel and CFRP,and discusses the maximum reinforcement quantity,minimum reinforcement quantity and calculation of reinforcement quantity in the reinforcement design of sticking steel and CFRP.It is pointed out that the maximum reinforcement quantity and minimum reinforcement quantity can be judged by the method of bonding steel and CFRP when the section of the member is known and the new calculation reinforcement is made.By simplifying the formula of the code,some parameters in the calculation of bonding amount of steel and carbon cloth are given,which can quickly calculate the concrete reinforcement amount of steel and carbon cloth bonding members.It has guiding significance to practical work.
