冷轧扭钢筋是国内近几年开发的一种新型经济断面建筑钢材,它集中了冷拨钢丝与热钆螺纹的优点,因而在相同条件下的混凝土构件中可以节省钢材3040%.本文在分析现有矩形截面冷轧扭钢筋的基础上,提出了另外几种新型截面,通过理论分析与对比试验,其综合性能均优于矩形截面材. Cold-rolled twisted steel is a new type of economical section construction steel developed in recent years, which concentrates the advantages of cold-laid steel wire and hot-rolled gadolinium screw, thus saving 3040% of the steel in the same conditions of concrete components.In this paper, On the basis of the existing rectangular cross-section cold-rolled twisted bars, several new sections are proposed. The theoretical analysis and comparison tests show that their overall performances are better than that of the rectangular sections.
