This paper presents the analysis results on shear behavior of reinforcement concrete beam using crack models by nonlinear finite element method. Two different crack models were used in F.E.M.(finite element method)' one was FCM(the fixed crack model) and the other was RCM(the rotated crack model). When the shear reinforcement ratios is 0~0.24%, RCM is similar to the behavior of the test on load-displacement, maximum load and crack distribution, while RCM is overestimated by 0.04%. FCM is generally overestimated compare to the results of the test, because crack distribution of diagonal-tension is different with the test. At the analysis of shear behavior governed by flexural-shear cracks, the analysis results also showed that RCM was effective.
