预应力筋空间曲线布置张拉伸长量计算

Count Pulling Force Length in Position of Bearing Tendon Capability Space Curve

预应力筋空间曲线布置时伸长量计算中的一些问题还有待进一步探索。实践证明:以单向转角小段分段计算再累加更接近实际张拉伸长量。

In the position of bearing tendon capability space curve,the pulling force length counts with many problems. In practice,we firstly count single turing section as sub-section. This would be more reach the actually pulling force.
