In this study, anti-symmetric bending tests and FE analyses of R/C deep beams with triple layered arrangements were carried out in order to make clear the influence on bond behavior by terminating the bars in the span. Especially, tension shift in the cut-off bars at the beam end was focused on. An equilibrium model between bond stress and shear reinforcement stress is used to explain the results. Consequently, in the ultimate state, the range of tension shift in the cut-off bars in the deep
