HRB500级钢筋抗拉强度标准值为500MPa,是一种强度高、延性好的新型钢筋,在国外已得到广泛应用。而我国《混凝土结构设计规范》(GB50010-2002)中尚未列入,为尽快实现与国际接轨,在我国工程领域推广种新型钢筋,需对HRB500级钢筋混凝土构件主要受力性能进行试验研究。
HRB500 steel bar tensile strength standard value of 500MPa, is a new type of high strength, good ductility, has been widely used in foreign countries. China’s “Specifications for Design of Concrete Structures” (GB50010-2002) has not yet been included. In order to achieve international standards as soon as possible and promote new types of steel bars in China’s engineering field, the main stress performance of HRB500-grade reinforced concrete members needs to be experimentally studied.
