摘要
介绍了预应力钢绞线的伸直性对预应力混凝土结构钢绞线筋束中的长度均匀性、张拉应力均匀性、疲劳性能、抗应力腐蚀性能等的影响。分析了影响钢绞线伸直性的因素,提出提高预应力钢绞线伸直性的几点措施和建议。
The paper introduces the effect of prestressed concrete steel strand straightness on the length uniformity, tension stress uniformity, fatigue property and stress corrosion resistance of strand tendon. The authors analyze the factors affecting strand straightness and propose measures and suggestion for improving strand straightness.
