摘要
本文提出了在预应力混凝土超静定结构中直接由主弯矩计算次弯矩的方法。该法不仅省去了目前常用的等效荷载法计算次弯矩时需要计算等效荷载和综合弯矩这两个步骤,而且还能准确计算预应力沿预应力筋变化时的次弯矩。
A direct method of calculating the secondary moments in statically indeterminate structures caused by post-tensioned tendons is presented. The method not only can avoid the calculations of equivalent loads and resulting moments when using the equivalent loads method to calculate secondary moments, but also can accurately calculate the secondary moments due to the prestressing which is varying along the tendons.
