In this research, we carried out finite element analysis depends on the variations such as the strength of the main bar, concrete, shear-span ratio(a/d) and existence of shear reinforcing bar. Throughout the results of FEM analysis, we were able to figure out how each vari ation can effect on shear performance. As the strength of concrete incr eased, the maximum shear force enhancement effect of each specimen was evaluated. As a result, the shear strengthening effect was 51~9 7% for shear reinforced specimens, and 26~44% for non-shear reinforced specimens. As the yield strength of reinforcing bars increases, the shear reinforcement effect of the specimen the specimens withou t shear reinforcement were 3%~6% higher than those with shear reinforce ment. Theoretical and analytical values were compared using the desig n equations obtained from the CEB code. Theoretical and analytica l values were compared using the design equations obtained from the CEB code. As a result, the errorrate was the highest at 3.64 in the S1.0-C 0 series and the lowest at 1.46 in the S1.7-C1 series. Therefore, the d esign equation of the CEB code is estimated to underestimate the act ual shear strength of deep beams that are not subjected to shear reinfor cement.
