本文进行了冷轧带肋钢筋砼与普通Ⅰ级钢筋砼结构及冷轧带肋双钢筋砼与冷拔丝双钢筋砼结构性能对比研究。得出冷轧带肋钢筋砼、冷拔丝双钢筋砼和冷轧带肋双钢筋砼础结构是具有显著经济效益的钢筋砼结构。在满足裂缝宽度、挠度等各项指标的情况下,提出了三种结构中的钢筋抗拉强度设计的合理取值,对今后制订、修订有关规范具有一定的参考价值。
In this paper, the structural properties of cold-rolled ribbed reinforced concrete and general grade I reinforced concrete and cold rolled ribbed double reinforced concrete and cold drawn twin reinforced concrete were studied. It is concluded that the cold-ribbed ribbed, cold-drawing double-reinforced concrete and cold-rolled ribbed double-reinforced concrete foundation structure is a reinforced concrete structure with significant economic benefits. In the case of satisfying various parameters such as crack width and deflection, the reasonable values of the tensile strength design of the steel in the three structures are proposed, which has certain reference value for the formulation and revision of relevant specifications in the future.
