This study experimentally investigates the effect of the wing wall transverse bar ratio and axial force ratio as parameters on the shear strength of RC column with a wing wall on Either One Side. Next, the accuracy of the evaluation formula for the shear strength of the current RC column with wing wall is examined by comparing the experimental results with the calculation results in which tensile bars are defined for each of the positive and negative directions. Furthermore, the applicability of the replacement section method, which evaluates the shear strength of a column with a wing wall on either one side by replacing it with a rectangular section, is examined.Finally, the applicability of the analytical model is discussed by comparing the experimental results with the analytical results obtained from a stable convergence algorithm applicable to columns with a wing wall.
