| 摘 要： | 探讨了后张预应力混凝土框架梁正截面承载力计算公式，提出了多层预应力混凝土框架梁的实用设计方法，此法考虑了各层预应力梁的相互影响，以正常使用要求为前提，同时满足了承载力要求。并通过算例，分析指出了现行设计方法的不足，明确了次轴力对预应力梁的影响。

| Abstract: | In this paper,the ultimate normal section load-bending capacity of post-tensioned prestressed beam is derived,and a practical design method for multistory prestressed concrete frame beam is present.This method can consider interaction among each prestressed concrete frame beam.Based on cracking-control,ultimate load capacity also can be satisfied.In the meanwhile,the example has shown that the insufficiency of current methods.The influence factor of secondary axial force is specified. |
