超长预应力束的应力分析

随着桥梁跨径的不断加大，预应力束也越来越长，由于钢束长度的不断增加，准确分析出预应力束各段应力对结构起着非常重要的作用。本文对超长钢束应力计算与实验资料做一比较分析。

Stress Analysis for Ultra- long Prestressed Gird

For increasing of bridge span, prestressed girds become longer and longer. So it is important for structures that accurately anlyze per section stress of prestressed gird. This paper compares ultra - long steel gird stress calculations with actural lab test results.
