摘　　要：研究CFL加固梁在热力耦合作用下的加固梁的变形特征具有重要的科学意义,采用理论分析研究方法,通过推导公式,对CFL加固梁挠度在温度和载荷作用下的耦合效应进行定量的探讨。分析结果表明:热力耦合对CFL加固梁的变形影响极小,与载荷产生的挠度相差几个数量级,可以忽略不计。It is very meaningful to study the deformation of the Strengthened RC beam with CFL. The deflection of the strengthened RC beam with carbon fiber-sheet is discussed using theory method. The results show that the deflection produced by thermal-mechanical coupling is very small, and because there are several orders of magnitude between the deflection produced by thermal-mechanical and force, it can be ignored.
