When installing a mechanical splicing joint in RC members, it may be difficult to secure the bond length of the main bar because of no bond resistance on the surface of a splicing unit. If a joint locates at the member end and is stored in the range of d (= effective depth), it will not become a problem since this range is excluded from the bond length of the main bar in the current design procedure. But it becomes difficult to secure the bond length when a mechanical splicing joint is installed on the intermediate position of a member length, and when it is installed in beam-column joint. In this study a method to include the region of a mechanical splicing joint into bond length was proposed, arranging an intensive shear reinforcement (ISR) at both side of the splicing unit. The mechanism was verified by experiment.
