In this study, six reinforced concrete (RC) beams with the sizes of 200x300x2000 mm3 were tested under fourpoint
bending to investigate the effect of fiber hybridization on the splice length of reinforcing bars. For this
purpose, the reinforced beams were designed as no fiber, single fiber (1% macro steel fiber) and hybrid fiber
(0.8% macro and 0.2% micro steel fiber) reinforced. Each beam was designed to include two bars in tension,
spliced at the center of the span. The splice length was selected so that bars would fail in bond, splitting the
concrete cover in the splice region, before reaching the yield point. In experimental work, the diameter of bars,
splice length and bar details was selected as constant while the fiber combination was variable. Finally, it was
found that although all beams had same splice length of steel bars the flexural performance of beams with steel
fiber was higher than beams without steel fiber. Moreover, the beams with hybrid steel fiber had highest load
carrying, energy absorption capacity and displacement ductility.
