摘要
通过对两榀双层双跨钢筋混凝土叠合框架（KJ—1，KJ—2）和-榀整浇框架（KJ—3）的试验，分析了叠合框架梁的受力性能，提出了叠合框架梁叠合面破坏机理及防止叠合面破坏的构造措施，证实了二次受力叠合框架梁中仍然存在荷载预压应力区，它对叠合梁抗剪有利。
The mechanical behavior of composite frame beam is analysed through the experiment with two composite frames which have two layers and two spans and with a poured frame. The destroy mechanism of composition plane is studied and some construction measures are presented to avoid this destroy. It is proved that there is still a prestress length caused load in composite frame beams, which is beneficial to the shearing composite beam.
