Abstract

The behaviors of deep beams failed in shear were investigated using 3D-RBSM, which is a rep- resentative method of discrete method that presents realistic behavior from cracking to the failure. Two deep beams without web reinforcement were analyzed having shear span ratio (a/d) of 0.5 and 1.5. Analytical re- sults were compared with the experimental ones in terms of load displacement graph and crack pattern and it was confirmed that RBSM is a useful tool for the analysis. Moreover, the strut width and high stress state as well as deformation were investigated three dimensionally and 3D behavior of deep beams due to shear span ratio was discussed. As a result, failure behavior of deep beams failed in shear was clarified by discussing the three-dimensional behavior.
