In the first part of this study, 36 prisms made of plain concrete, steel fiber-reinforced concrete, and hybrid fiber-reinforced concrete (HyFRC) were tested under quasi-static load to account for variability in fiber specifications. Two types of steel fibers with hooked ends and two types of polymer fiber—namely, polypropylene and polyester—were used. The HyFRC prisms exhibited approximately 10 to 15 times the enhancement in toughness compared to similar plain concrete prisms up to failure. In the second part of the experimental program, four types of beam-column connections were tested under cyclic loading. Test results established that the addition of hybrid fiber in the joint region of the specimens is effective in enhancing their displacement ductility and energy dissipation capacity. Detailed measurement of strain distributions along the main reinforcement of the specimens showed that there was substantial reduction in strain levels in the specimens with HyFRC in the joint region.
