title = "Bond behavior of GFRP bars embedded in fiber reinforced concrete",
abstract = "In this study a total of 90 cubic specimens were prepared to investigate the pullout behaviours of the sand-coated and helically-wrapped GFRP bars as well as steel bars in matrix reinforced with FRC (steel, PP and PVAa fibers) and PVAb-ECC. The results of direct pullout testing were presented and analyzed with the aim of elucidating the effect of surface treatment of bar, fiber type, and fiber volume fraction in interface and suggesting the effective evaluation method for the improved ductility. The structural fibers (steel, PP, PVAa fibers) and PVAb-ECC in the interface changed the interfacial bond behaviors, but bond failure modes largely depended on the interfacial property with the rebar. The fiber's crack closing resistance, determined by evaluating toughness indices, was used to determine optimum amount and type of fibers in the composites. The effect of concrete matrix with the structural fibers in the interface was apparent rather than that of engineering cementitious matrix with PVAb fibers.",
