However, in practical application, the fabricated steel structure joint cannot meet the assembly requirement of simple and rapid construction.

Common steel structure connection modes include three modes of welding, high-strength bolt connection and bolt and welding mixed connection. The high-strength bolt end plate connection is one of widely adopted and convenient component construction site assembly connection modes, and the high-strength bolt end plate connection is generally that an end plate and a steel beam are welded together in a factory and then are fixedly connected through a high-strength bolt on site. The traditional end plate is connected with two structural forms, one of the two structural forms is an outward extending type, namely the end plate extends out of the flange of a beam, high-strength bolts are concentrated around the flange, and the outward extending part is usually provided with stiffening ribs; the second is a flush type, namely a high-strength bolt is arranged between the two flanges. The end plate connection structure usually cannot meet the mechanical property requirement of rigid connection, and the connection structure of the node can generate larger deflection and deformation, thereby causing serious influence on the stability of the node connection structure.
