在一次受力下CFRP布加固混凝土矩形柱抗压强度理论公式的基础上，按照叠加原理和强度代换原理推导了二次受力下CFRP布加固混凝土矩形柱抗压强度理论公式，并采用ANSYS软件对CFRP布加固混凝土柱的二次受力性能进行了数值模拟，将试验值与理论值及ANSYS值进行对比，结果基本吻合，证明了理论推导的科学性，为加固工程提供了一定的理论参考．

Abstract： On the basis of the compressive strength of rectangular concrete columns with CFRP sheets under first loading, the theoretical formula about compressive strength of rec- tangular concrete columns with CFRP sheets under secondary loading was derived through the superposition principle and strength substitution principle. The performance of the me- chanical properties of rectangular concrete columns with CFRP sheets under secondary load- ing was simulated through ANSYS software. By contrasting the test values, the theoretical value and the ANSYS simulation value, the results were basically consistent, which proves that the theoretical derivation has the scientific nature and provides certain reference for rein- forcement projects.
