摘　　要：本文介绍了两棍高效预应力混凝土（ＨＰＣ）叠合框架模型试验（１：３）的试验结果，并与承载力及配筋指数相当的混凝土（ＲＣ）叠合框架模型试验（１：３）的试验结果进行了对比。分析了ＨＰＣ模合框架的受力性能、应变变形特征、裂缝特点和二次受力特征系数。提出了作用于预制构件内力的整体作用系数ａ的概念。Tha experimental results of two 1:3 scale models of high efficient prestreued concrete(HPC) composite frames and the comparative analysis with RC comparative analysis having the same load-bearing capacity are reported in this paper. The mechanic behavior of HPC coposite frarnes, their strain and deformation properties, and the coefficient of two-stage loadinog are ana- lyzed. Besides, the ooncept of integral effective coefficient a of internal forces in sections of pre- fabricated oomponents is also presented.
