| description | The sudden incidence of shear failure in the structural elements of the concrete entails using shear reinforcement in order to enhance the ductility. This study presents the use of an innovative steel reinforcement technique in reinforced concrete beams. The steel bars were composed in a form like that of the flamingo bird. Five beams with dimensions of 200 mm x 300 mm x 1500 mm were cast, cured, and evaluated in shear under four-point bending. One beam has been reinforced using the conventional steel stirrups as a control beam, while the new flamingo technique reinforced the other four beams in the shear zone with the parameters of variation in the inclination and lengths of the lower and upper free ends. The results revealed that the use of the flamingo technique has perfectly increased the shear capacity of the beam, and ultimate deflection, increased the shear ductility and decreased the crack width. |
