The failure of such walls is due in the majority of cases to shear. Accordingly, this study is elaborated to compare three different analytical approaches regarding the prediction of lateral shear resistance of confined masonry walls. The principle is to calculate the total lateral resistance of the wall by considering the participation of both structural members, i.e. the brick panel and the RC tie-columns. In this study, the tie-columns participation is evaluated from the dowel action of confined columns' reinforcement and the brick panel participation is evaluated using the theory of elasticity with different assumptions. A full scale experimental study on confined clay brick wall subjected to a constant vertical and quasi-static cyclic lateral loads is performed to estimate the efficiency degree of each method. Depending on the method, the comparison of calculated values to test results has shown that the real lateral resistance is overestimated by 17.54%, 42% and 54.1%. On the light of these results, the appropriate approach to predict the shear capacity of the masonry structural member needs to be selected carefully to be consistent to a certain extent with the results of the experimental testing.
