The effectiveness of web shear steel ratio in Deep beam was performed by nonlinear finite element method. Results of FEM were compared with ACI code and equations of reference. In concrete shear strength, ACI results had 1.2~1.5times safe factor for FEM. Presence of vertical web reinforcement increased ultimate shear strength of deep beams, However, vertical stirrup's effectiveness seamed to increase for beams with a/d>1.0. Horizontal web reinforcement appeared to have little influence on the ultimate shear strength. Its influence was more noticeable in beams with a/d<1.0
