This paper describes the bond splitting strength of all lapped splices at the same section with large-diameter bars. In this study, experiments with lapped splices subjected to pure bending and bending with shear were conducted. Examined was the applicability of the equation for bond splitting strength proposed for the main reinforcement D19 in the past to the conditions under large-diameter bars. From this investigation, it became clear that the bond splitting strength of lapped splices with large-diameter bars could be estimated sufficiently by the proposed equation for bond splitting strength based on the main reinforcement D19, and data for the design of the lapped splices with large-diameter bars were obtained.
