Effect of Fiber Reinforcement on Bond Strength of Tension Lap Splices in High-Strength Concrete

This research evaluates the effect of steel fiber reinforcement on the bond strength and ductility of the mode of bond failure of tension lap splices anchored in high-strength concrete (HSC) test specimens. 12 full-scale HSC beam specimens were tested. Each beam was designed with bars spliced in a constant moment region at midspan. Test results indicated that the use of steel fibers in the splice region increased the bond strength and the ductility of the mode of failure of the beam specimens.
