An interior beam-column joint in a ductile moment-resisting reinforced concrete frame was assumed and eight different cases of bond characteristics of column reinforcement in the joint were hypothesized. A previously developed computer program was applied to each case, and the bond deterioration processes of column reinforcement in the joint under seismic loading were investigated theoretically through the hysteretic behavior of column-end hinge, pullout of column reinforcement from joint, etc. According to the bond strengths in the joint the hysteretic behavior of column end hinge showed drastic changes and indicated the importance of assessing "bond" in the joint, and farther, it was explained theoretically that both the reduction of flexural moment capacity at column end and the compressive failure of hinge concrete were accelerated considerably when bond strength in the joint was inadequate.
