摘要
我国建筑用钢的钢筋等级普遍偏低,导致建设成本的较大增加和自然资源的过度消耗。在国家节能减排的产业政策支持下,HRB400级钢筋是当前钢筋强度升级换代的最佳选择,它的推广应用已成为我国建筑工程用钢亟待解决的问题。文中通过实际调研、理论分析和工程实例,指出合理使用HRB400级钢筋可带来显著的经济效益。
The grades of steel bars in construction area are generally low in China, which leads to the increase of construction cost and waste of natural resources. Under the supporting of national Industrial policies - Energy Conservation and Emission Reduction, Grade HRB400 steel bars become the first choice in updating the steel bar grades, and their promotion and application have become a burning issue in construction area. This paper, through actual research, theoretical analysis and construction examples, concludes that application of HRB400 steel bars can bring about significant economic benefits for the potential users.
