超长预应力束的应力分析

Stress Analysis for Ultra- long Prestressed Gird

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。

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.
