摘要
通过2榀预压装配式预应力混凝土框架节点的拟静力试验，了解了其梁端截面的应变分布、破坏状态和极限承载能力；分析了该种纯预应力构件的延性，该种节点支座截面具有较好的延性，为弯矩调幅提供了条件；用计算程序分析了支座截面弯矩调幅系数与受压区高度的关系。
Two specimens of prestressed fabricated beam-column subassembly were tested under cyclic loading. By analyzing the results of the experiment, the strain distribution at the sections of beam ends, failure behavior and ultimate load-bearing capacity of the connections are found out. The results of the experiment showed that these connections have better ductility. The relation between coefficient of modulation of bending moment and height of stressed region is put forward by a step-by-step general section analysis procedure.
