Reinforced concrete(RC) walls are used in many buildings as a structural element to resist lateral load such as earthquake load. The accurate prediction of failure mode and shear strength of RC wall is important for both code-based design and performance evaluation. In this study, the reliability of the analysis model and method is verified using the non-linear finite element analysis. Also, the failure mode and shear strength are evaluated through analysis of main variables and compared with design code of each country. The main conclusions are as follows: (1)The aspect ratio is the dominant variable in the failure mode and horizontal/vertical reinforcement ratios are main variables affecting the type of shear failure mode. (2)The lower aspect ratio and the higher axial load ratio, the more rapidly deformation ability and load after maximum load decrease. (3)The lower concrete compressive strength, the more rapidly rigidity decreases after cracking and Even if the horizontal and vertical reinforcement ratios increase, the behavior is similar. (4)The increasing of concrete compressive strength and axial load ratio results in increasing of shear strength, whereas the influence of horizontal and vertical reinforcement ratios on the increase in shear strength varies depending on the aspect ratio.
