In this paper a macroscopic model for evaluating the maximum strength of framed RC shear walls with an opening is proposed, and its analytical method is shown. Furthermore, the validity of the macroscopic model and its analytical method is investigated by analyzing the maximum strength of fifty-three specimens of the framed shear walls with an opening. From the analysis, it is obtained that the values of mean, standard deviation, and coefficient of variation for the ratios of the observed maximum strengths to the analytical ones are 1.039, 0.131, and 0.126, respectively. This result shows that the macroscopic model and its analytical method are well adequate.
