[0002] With the rapid development of modernization and national economy, the use of building functions is becoming more and more complex. For multi-story, high-rise and super high-rise buildings, traditional concrete structures can no longer meet the functional requirements. Steel structures are increasingly used in building structures due to their excellent performance. In order to ensure the economy of the building, save costs and reduce the deadweight of the superstructure, the study of more reasonable connection forms between I-shaped steel beams and box-type steel columns with unequal cross-sectional sizes of upper and lower columns is a focus of current research on prefabricated steel structure technology.

[0003] At present, the beam-column connection methods used in steel structure construction projects mainly adopt the methods of full welding connection and bolt welding connection. Such nodes have the advantages of high bearing capacity, high rigidity, simple and clear force transmission path, etc. However, the on-site welding workload of such nodes is large, the working conditions are easily affected by the outside world, and the quality of the welds is difficult to guarantee. Under the action of a large earthquake, stress concentration is easy to occur at the welds, resulting in brittle failure. In addition, the construction speed is slow and the quality is difficult to guarantee, which has long troubled architectural design and construction practitioners. These two connection methods are difficult to adapt to the requirements of the national construction industrialization and meet the requirements of design standardization, factory production, and construction assembly.
