摘　　要：为了改善装配式预应力混凝土框架节点的抗震性能,对国内外装配式预应力混凝土框架结构的节点形式进行回顾,总结目前存在的问题和缺陷,在此基础上提出一种新型的装配式预应力混合梁柱节点。以一中节点为例,评价了该节点的抗震性能并阐述了施工过程。研究结果表明:该种节点的耗能能力强,具有良好的抗震性能,同时具有很强的自恢复能力,是一种值得推广的节点形式。In order to improve the seismic capability of the precast prestressed concrete frame joint, the joint form of precast prestressed concrete frames at home and abroad is indicated. First, the joint form is reviewed and the shortage is summarized. Second, a new prefabricated prestressed concrete hybrid beam-column joint is introduced. As an example, the seismic capability of a middle joint is evaluated and the construction approach of it is illustrated in detail. The results demonstrate that the joint has significant energy dissipation levels while maintaining a large level of self-centering capability, and is worthy of promotion.
