To clarify whether the bond behavior of FRP rods fabricated by 3DP can be evaluated, a pull-out test was carried out with CF incorporation rate and the height of ribs(H) to the spacing of ribs(L) (H/L). As a result, it was found that the effect of increasing CF incorporation rate on the improvement of FRP rod bond performance is small, and bond stress showed a different trend from that of reinforcing bars. In addition, it was suggested that the effect of H/L on bond stress in FRP rods can be evaluated by appropriating CF incorporation rate.
