摘要
对目前国内使用的几种钢筋的抗拉强度和伸长率值的分析结果表明 :混凝土结构中应发展热轧新Ⅲ级钢筋作为主体钢筋品种 ,并在梁柱构件中取代Ⅱ级钢筋作受力主筋使用。而冷加工钢筋 ,尤其是冷轧扭钢筋 ,用于板类受弯构件中具有较多优越性 ,宜大力推广应用。
The analysis of tensile strength and tensile ratio of several sort of rebar currently used in China shows that new grade III of hot-rolled steel bar shall be the popular sort to be used in concrete structure. It shall be used as main reinforcement in beam and column components to replace rebar of grade II. However cold-finished steel, especially cold rolled twisted steel is of more advantages in components in bending such as slabs. Therefore it shall be popularized.
