Abstract: Heat-treated ribbed bar 630 (HTRB630) is a new type of reinforcing steel produced in China. The tensile properties and low-cycle fatigue properties of HTRB630 high-strength steel bars after exposure to high temperature are ...

Abstract: To explore the application of heat-treated ribbed bar (HTRB) type HTRB630 high-strength steel bars in reinforced concrete bridges, the tensile test and high-cycle fatigue test are carried out. Then, the high-cycle fatigue ...
