摘　　要：无粘结预应力混凝土(unbonded prestressed concrete,简称UPC)结构具有结构恢复性能好、摩擦系数小、施工方便等特点,故其被广泛应用在高层建筑、大跨度工程中。研究从UPC结构中柱节点的特性、节点研究的重要性、其国内外研究发展状况和目前抗震性能的分析方法等角度,对UPC结构中柱节点抗震性能的相关研究进行了分析和归纳。结论总结如下:目前UPC结构的研究主要是针对无框架边节点以及梁的试验研究,而对UPC结构中柱节点的试验研究甚少。Concrete pressed with unbonded(UPC)structures have the characteristics of good structural recovery performance,low friction coefficient,and convenient construction,and are widely used in high-rise buildings and large-span projects.We will analyze and summarize the relevant research on the seismic performance of column nodes in UPC structures from the perspectives of the characteristics of column nodes,the importance of node research,the development status of domestic and foreign research,and the current analysis methods of seismic performance.The conclusion is that current research on UPC structures mainly focuses on experimental studies of non frame edge nodes and beams,while there is little experimental research on column nodes in UPC structures.
