| 摘 要： | 《混凝土结构设计规范》(GB50010—2002)推出的HRB400级钢筋与旧规范《混凝土结构设计规范》(GBJ10-1989)中的Ⅱ级钢筋相比，HRB400级钢筋强度明显提高，延性好，焊接工艺已完善，生产成本低，用于混凝土结构可节省用钢量，应在工程建设中大力推广应用。

| Abstract: | Compared with the steel bar of Grade II in the old code GBJ 10 -1989 Design Code for Concrete Structure, the steel bar of Grade HRB 400 in GB 50010 -2002 Design Code for Concrete Structure has been obviously improved in strength. With good ductility, perfect welding technology and low production cost, it can reduce the steel consumption in concrete structure and should be introduced into engineering construction application. |
