装配式建筑框架节点研究综述

装配式建筑因施工周期短、节约资源等优点得到了广泛应用，其框架节点是结构受力的主要部位。为剖析装配式建筑框架节点关键技术与发展趋势，通过利用软件CITESPACE对中国知网收录的有关装配式建筑框架节点的核心期刊169篇文章和Web of Science核心合集的456篇文献进行发文量分析，文献所属研究机构以及关键词共现分析等进行对比。结果发现：装配式建筑框架节点的研究发文量总体呈上升趋势，美国中心性最强，法国位居第二，同济大学和东南大学在此领域的研究较多；国内外对所属装配式节点各领域之间的研究较为紧密，研究框架逐渐完整，其中抗震性能、耗能能力是装配式建筑框架节点研究的重要内容，PEC结构和自复位结构是其研究的新内容；数值模拟方法在众多研究中都被应用，其与试验方法的结合是当下装配式建筑框架节点研究的热点。本文在总结装配式建筑框架节点优缺点的基础上，提出了存在的问题并进行探讨。

A review of research on assembled building frame joints

Assembled buildings are widely used due to the advantages of short construction period and resource saving. The frame nodes of assembled buildings are the main parts of structural stresses. In order to analyze the key technologies and development trends of the assembled building frame nodes, by using the software CITESPACE, 169 articles in the CNKI core journals and 456 articles in the WOS core collection about assembled frame nodes were analyzed for their publication quantity, co-occurrence analysis of the research institutes and keywords co-occurrence analysis and made a comparison, the results show that: the number of research papers published on assembled frame nodes is on the rise. America has the highest centrality, and France ranks second. In China, Tongji University and Southeast University have more researches in this field. At home and abroad, the research on each small field of the assembled node is relatively close, and the research framework is gradually complete. Among them, seismic performance and energy dissipation capacity are important contents in the research of assembled building frame joints. PEC structure and self-reset structure are the new contents of its research. Numerical simulation has been applied in many researches, and its combination with experiment is the hotspot of assembled building frame node. On the basis of summarizing the advantages and disadvantages of assembled building frame node, this paper puts forward the existing problems.
