| 摘 要： | 首先介绍了采用后张预应力筋将预制梁和柱构件拼装在一起组成的框架结构的基本形式及特点，接下来对两榀预制框架中节点进行了低周反复加载试验研究，并对一榀三层两跨框架结构进行了弹塑性静力分析，试验和理论分析结果表明经过合理设计的部分无黏结预制预应力混凝土框架结构能够满足抗震设防的要求，且卸载后残余变形较小，具有较强的恢复性能。

| Abstract: | The basic concept and characteristic of the precast concrete frame, whose beam and column elements are connected by partially unbonded post-tensioned and prestressed tendons, are introduced. In the following, experimental study of two precast beam-column subassemblies and pushover analysis of a two-span, three-floor precast prestressed concrete frame are conducted. Experimental and analysis results indicate that the reasonably designed partially unbonded precast prestressed concrete frames could fulfill the aseismic requirement. |
