摘　　要：通过 4榀叠合框架的足尺实验 ,研究了二次受力叠合框架梁的力学性能和破坏形态。根据实验结果分析了顶层角节点受弯钢筋的锚固性能 ,提出了角节点受弯负筋的锚固构造 。In order to investigate mechanical characteristics and damage features of the model on sections of two-stage loading composite frame beams,experiments on 4 composite frames were carried out.Based on the experimental results, bond properties of bars subjected to negative moments in composite frame corner joints are analyzed, and anchorage constructions of bars are presented. All anchorage constructions of bars might be referred to practical design.
