The bonding performance of steel fibers (i.e., straight and hooked-end steel fibers) in hybrid steel fibers reinforced ultrahigh-performance concrete (UHPC) was investigated through single steel fiber pullout tests. Based on the load-displacement curves of steel fibers, the effects of hybrid steel fibers and their volume fraction on the bonding properties between hybrid steel fibers and UHPC were analyzed, and the correlation between the fiber-UHPC interfacial bonding properties and the compressive strength of UHPC was discussed. The pullout processes of steel fibers in hybrid steel fibers reinforced UHPC were clarified, and the pullout load-slip models of the straight and hooked-end steel fibers during the pullout processes were proposed. It is indicated that the hybrid of steel fibers could achieve an optimum interfacial bond performance between steel fibers and UHPC at the volume fraction of both straight and hooked-end steel fibers embedded in the UHPC matrix of 1%.
