［摘要］关节轴承节点是机械金属结构中一种重要的连接形式，由于其受力明确、制作简单、安装方便和外形美观等特点，已成为现代钢结构中最常采用的节点形式之一。 首先介绍了关节轴承节点的研究现状，然后总结了关键问题的研究成果，同时列举了关节轴承节点的在工程中的实际应用，最后指出了关节轴承连接节点存在的主要问题。现有研究表明，关节轴承节点具有良好的受力性能及延性，但是由于建筑钢结构类规范对其还没有较为详尽的规定，一定程度上制约了其应用和发展，有必要对关节轴承的材料性能、节点承载能力、延性和抗震性能和构造安装要求进行系统的研究。

Abstract:Spherical plain bearing joint is an important form of connection mechanical metal structure, which has become one of the most commonly joints in the modern steel structure because of its clear mechanism, simple production, convenient installation and beautiful appearance. The research status  of spherical plain bearing joints was introduced firstly, and then the achievements of key issues were summarized. The practical application of the spherical plain bearing joint in engineering was enumerated. Finally the main problems of the spherical plain bearing joints were pointed out. Current study shows that this joint has good mechanical behavior and ductility. However, the detailed provisions in the steel structure specification have not been systematically conducted, which  restricts its wide acceptance to a certain extent. It is necessary to study the material properties, joint bearing capacity, ductility, seismic performance and installation requirements of the joints.

Keywords:steel structure; pin-connected joint; spherical plain bearing joint; engineering application; research progress
