Finite element analysis was performed to replicate the test conditions of a reinforced concrete beam with a guaranteed hinge position having de-bonding of longitudinal rebars. From the analysis, it was found that the existence or nonexistence of longitudinal rebar bonding in the section from the beam end to the assumed hinge position did not affect the shear force-member drift ratio relationship or the damage conditions. In addition, the crack range could be suppressed with almost no decrease in stiffness through de-bonding of only the longitudinal rebars at the four corners instead of all the first layer rebars.
