冷拨低碳螺纹钢丝预应力混凝土多孔板性能的试验研究

Experiment and Analysis for the Behaviours of the Prestressed Concrete Hollow-Core Slabs with Cold Drawn and Spiraled Low Carbon Wire

本文在冷拨丝预应力混凝土多孔板的分析研究基础上,对九块冷拨低碳螺纹钢丝预应力混凝土多孔板的性能进行了试验研究,并通过理论计算,分析讨论了试件的裂缝、挠度、破坏形态,以及延性性能。在这些试验研究和理论计算的基础上提出了有关的设计参考意见。

On the basis of the analyses and researches of the prestressed concrete hollow-core slabs with cold drawn low carbon wire, nine full-scale prestressed concrete hollow-core slabs with cold drawn and spiraled low carbon wire were tested and the cracks, displacement, failure form and ductility behaviour of these slabs were analysed and discussed with quantities of theoretical calculations. According to the experimental researches and theoretical calculations, some recommendations for design are given in this paper.
