In the application of multiple Carbon Fiber-Reinforced Plastic (CFRP) plates onto a structural steel member, stepping of the CFRP plate ends is often adopted to prevent debonding. This approach requires the nonuniform extension of CFRP plate lengths. In this study, to shorten the length of CFRP plates, a nonuniform overlapping arrangement of several CFRP plate ends was proposed and the theoretical conditions of arrangement were proposed. Additionally, the design for the stepped-end arrangement of CFRP plates under a uni-axial load was shown. It was confirmed with stress analysis that the stress in the steel plate was reduced to the design value by bonding the CFRP plate with the proposed stepped ends.
