"High-strength shear reinforcement bar Ulbon 1275" spiral, tie bars, stirrups
Compared to ordinary reinforcing bars (SD bars), the design stress can be increased up to four times, significantly reducing the amount of shear reinforcement used.
The 'High-Strength Shear Reinforcement Bar Ulbon 1275' is a deformed PC steel bar certified by the Minister of Land, Infrastructure, Transport and Tourism, with a yield point of 1275 N/mm² and a tensile strength of 1275 N/mm². Compared to conventional ordinary rebar (SD bar), it can achieve design stresses up to four times greater, significantly reducing the amount of rebar used and contributing to improved work efficiency, cost reduction, and shortened construction periods on site (resource conservation, CO2 reduction). Additionally, by accommodating the high-strength requirements of columns and beams in reinforced concrete (RC) structures, it enables the construction of super-tall buildings over 60 meters. * A design method using bond-splitting reinforcement bars has been established, allowing for reinforcement of up to 1.5% as P_w + P_b (bond-splitting reinforcement ratio) based on plastic theory shear strength formulas and patented methods by Netsuren.
