Deep Beams, shear behavior, fiber reinforced concrete, hybrid fibers, experimental studyAbstract
This work presents results of an experimental campaign in which the strength and ductility contribution of the steel and polypropylene fibers in shear behavior of DB was evaluated. DB with traditional steel bars and stirrups, and steel fiber reinforced concrete (SFRC) and hybrid fiber reinforced concrete (HRFH) beams with a 33% reduction in reinforcement were tested in flexion. with vertical stirrups and without horizontal stirrups. The DB of concrete with fibers reached maximum loads between 4% and 8% higher than the beams with minimum shear reinforcement and showed a higher residual strength after peak load.
