Closed-type shear reinforcement bars for columns and beams - Koryo hoop bars
Improving the seismic resistance of buildings and rationalizing construction.
In conventional 135° hooked shear reinforcement bars, when tensile forces are applied to the shear reinforcement bars, pullout occurs at the hook section. Furthermore, if the cover concrete spalls, the pullout becomes even more significant, and there is a possibility that the hook may disengage from the main bars. These factors weaken the confinement effect of the shear reinforcement bars on the core concrete and the buckling prevention effect of the main bars, resulting in very poor ductility. Core hoops (hoop bars, stirrup bars) joined by butt welding exhibit the reinforcing effect of shear reinforcement bars and significantly improve the ductility of columns and beams. Additionally, since it also enhances "constructability" and "shortens construction time," we encourage you to consider this option.
