To research the applicability of equal strength substitution method applied to concrete beams with steel plates, the effects on application range of equal strength substitution method by the initial reinforcement ratio and the strengthened moment design value are discussed.In this paper, the calculation methods of equivalent substitution and Design Code for Strengthening Concrete Structure are adopted to calculate five kinds of single-reinforced rectangular cross-section concrete beams of typical section size by adjusting the initial reinforcement ratio and the strengthened moment design value.The dosage of steel plates is obtained through the comparison of the equal strength substitution and code calculation methods, which is used to obtain the relationship of initial reinforcement ratio, the area ratio of steel plates calculated by the equal strength substitution and code calculation methods and the moment ratio of strengthened and initial ultimate moment. The result shows that equal strength substitution method is not applicable universally, which is feasible only within the scope of certain.
