不对称预应力管道中钢绞线张拉伸长值计算

Tension and Elongation Value Calculation of Asymmetric Prestressed Steel Strand

本文介绍了预应力管道中钢绞线在对称张拉、不对称张拉、单端张拉情况下伸长量计算过程,着重介绍不对称预应力管道张拉过程中0位移点的确定方法,并分别计算出0位移点两边钢绞线的不同伸长量。

This paper introduces the calculation of tension and elongation value of symmetric tension, asymmetric tension, and single ended tension. It focuses on the determination of 0 displacement point in asymmetric prestressed pipeline tension process, and the calculation of different elongation value at the two side of steel strand.
