摘要:
工程中应用的细直径钢筋进场前均是盘圆形式,在使用前需进行调直加工.针对新近推出的HRB400(Ⅲ)级钢筋中的直径为6,8,10 mm的细直径钢筋,对其调直前后的力学性能进行了试验研究.通过试验结果对比分析,得出调直后的HRB400(Ⅲ)级细直径钢筋强度(屈服强度和抗拉强度)略有降低或基本持平;延性方面,伸长率δ5略有增加,均匀伸长率δgt略有降低,但各性能指标仍满足标准规范的规定,且有一定的富余.工程应用时,可不考虑调直工艺对HRB400(Ⅲ)级细直径钢筋性能的影响,同时,采用均匀伸长率δgt代替伸长率δ
Abstract:
The fine-diameter steel bars used in the project are all disc circular before entering the field, and need to be straightened before use. The mechanical properties of the 400,6,8 mm diameter steel bar with a diameter of 10,400,5 mm in the newly launched HRB400(III.) grade steel bar were experimentally studied. Through the comparative analysis of the test results, it is concluded that the strength (yield strength and tensile strength) of HRB<> (III.) grade fine diameter steel bar after straightening is slightly reduced or basically flat. In terms of ductility, the elongation δ<> increased slightly, and the uniform elongation δgt decreased slightly, but the performance indicators still met the requirements of the standard specifications and had a certain surplus. In engineering applications, the influence of straightening process on the properties of HRB<> (III.) grade fine diameter steel bar can be ignored, and at the same time, uniform elongation δgt is used instead of elongation δ
