Therefore, how to effectively improve the collapse resistance of the building structure is a current research hotspot. In addition, the current fabricated building is regarded by the current engineering community because of many advantages such as safe and convenient construction, short construction period, pollution reduction and the like. In a complete building structure, the nodes are key factors influencing the performance of the building structure. In traditional construction, the I-shaped beam and the column are connected in a welding mode or in a bolt connection mode, the failure mode of the connecting joint in the mode is that the beam flange is cracked when an anti-collapse experiment is carried out, the bearing capacity is reduced due to the cracking of the flange, the full play of a catenary mechanism is affected, and the residual stress is generated and the performance of the catenary mechanism is further affected due to welding on site. In the construction process of the fabricated building, the field operation can affect the construction process and the quality is not easy to guarantee, so that all parts are intensively transported to the construction site for assembly after being prefabricated in a factory during the construction of the fabricated building.
