摘要:
螺旋肋钢丝(简称PC棒)是我国新研制开发的用于顸应力混凝土结构的新型钢丝.通过对28个先张法构件端部区域混凝土应变的量测,分析了PC棒预应力传递长度范围内混凝土应变和应力的变化规律以及主要影响因素,提出了PC棒预应力传递长度计算公式的建议,为PC棒的工程应用提供了依据.
Abstract:

Spiral rib steel wire (referred to as PC rod) is a new type of steel wire newly developed in China for stressed concrete structures. By measuring the concrete strain in the end area of 28 pre-tensioned members, the variation law of concrete strain and stress within the prestress transfer length of PC rod and the main influencing factors were analyzed, and the calculation formula of PC rod prestress transfer length was proposed, which provided a basis for the engineering application of PC rod.
