空间网格结构节点刚度是近年来建筑结构领域的热点研究课题之一。分析了空间网格结构节点刚度的数学模型、不同节点体系节点刚度、半刚性节点杆件力学模型以及空间网格结构节点刚度分类的研究现状，总结了现有研究成果以及尚需深入研究的主要问题。文献分析表明，目前国内外对钢框架结构梁柱节点刚度的研究已经比较成熟，研究成果已经引入相关设计规范，然而，对空间网格结构节点刚度的研究还不够完善，远不能满足现代结构设计技术的需要。因此，有必要进行更多更深入的试验和理论研究，并进行系统的分析和总结，以提高现代空间网格结构的设计理论与技术，进一步促进空间网格结构的应用和发展。

In recent years,the joint stiffness of the spatial structures has become one of the major research in the field of building engineering.In this paper,a state-of-the-art review of research on the joint stiffness is presented,including the mathematical models,the rigid properties of different joint systems,the models for members with the semi-rigid joints and the classifications for the joint stiffness.The research findings and fur-ther research concerns are presented as well.In general,the research work on the beam-to-column joints of steel frames is relatively mature,and the research results have been used in some specifications.However,the research on the joint stiffness of the spatial structures still cannot meet the demands of modern structures. Therefore,for the application and the development of spatial structures,more experimental and theoretical studies need to be carried out to improve the design theory and technique of the modern spatial structures.
