摘　　要：在国内外研究的基础上,提出一种新型装配整体式混合框架结构体系.首先,介绍了此结构体系中约束混凝土柱、钢筋混凝土组合梁以及预制板的制作.其次,通过柱-柱节点和梁-柱节点的受力试验得到以下结论:装配柱的抗倒塌性、弹塑性转角以及延性系数要比现浇柱的更加优越;设有外包钢管的装配式柱构件的滞回曲线呈理想的梭形,其柱脚有很好的耗能性能,故而使梁-柱节点安全可靠.最后,通过该结构体系的实际工程应用表明该结构具有节能环保、节省资料和劳动力、减少施工工期等特点.On the basis of domestic and international research,a new hybrid assembly integral frame structure has been proposed. Firstly, the paper introduces the construction of confined concrete column, reinforced concrete composite beam and prefabricated panels. Secondly ,the following conclusions are obtained by making the stress tests of the column joints and the beam column joints：anti-collapse of the assembly column, elastoplastic comer and ductility factor are more superior than the cast column;It is an ideal spindle that the hysteresis curve of the assembled monolithic column which has outsourcing steel, and the column foot of assembly monolithic column has a good energy performance. Therefore ,the beam column joint is safer and more reliable. Finally, the practical application of the architecture shows that the structure has the characteristics：energy saving, environmental protection, saving material and labor force, reducing construction period and so on.
