[0002] Steel structure connectors are various parts used to connect steel components, and play a vital role in the design and construction of steel structures. The connection forms of steel structure connectors can be roughly divided into welding connection, bolt connection and bolt-welding mixed connection. The node strength of welded connection is high, but since welding is required on site, the quality of the component welds cannot be guaranteed, and the bearing capacity and energy consumption capacity of the node area are the core of prefabricated structure research, and have high requirements on the environment and workers' technical level. The construction speed of bolted connection nodes is fast, but the more bolts there are, the greater the additional bending moment, and too many openings will weaken the cross-section to a certain extent, which will have a certain impact on the stress performance. The node of bolt-welding mixed connection combines the advantages of the above two connection methods, but the construction sequence has a certain impact on the node performance. The initial strain generated by welding and the high temperature at the welding point inevitably cause the component to bend and deform.
