Background
In the field of structural engineering, compared with a traditional concrete structure, the steel structure has the advantages of high strength, light weight, good ductility and toughness, good comprehensive anti-seismic performance and the like. The earthquake damage of the steel structure mainly comprises the forms of damage of column foot foundations, damage of beam column node connection, damage of other connection parts, brittle fracture of large-section components, large residual deformation of the construction by adopting the thin-wall section components, damage of the components, integral collapse of the structure and the like. The beam column node connection of the traditional steel structure system is widely applied to welding rigid connection in actual engineering, and because the stress peak value of the beam flange welding seam is at the starting and extinguishing positions of the welding seam, the connection is more likely to be broken and torn at the welding seam, so that the plastic rotation capacity of the connection is poorer, the beam column connection welding seam of the traditional steel frame node is easy to destroy, and the post-earthquake repair is difficult to realize.
The Chinese patent document with the publication number of CN115538599A discloses a post-earthquake repairable beam column connecting node with a built-in energy consumption beam section, which comprises a steel column, brackets, a steel beam, a web connecting plate, a lower flange connecting plate and a mild steel damper; one end of the bracket is arranged on the steel column, and the bracket upper flange at the other end of the bracket is in butt joint and fixation with the steel beam upper flange at one end of the steel beam; the bracket web at the other end of the bracket is slidably connected with the steel beam web at one end of the steel beam through a web connecting plate, and the bracket lower flange at the other end of the bracket is slidably connected with the steel beam lower flange at one end of the steel beam through a lower flange connecting plate; the length of the bracket lower flange is smaller than that of the bracket web, the length of the steel beam lower flange is smaller than that of the steel beam web, and when the bracket is in butt joint with the steel beam, the soft steel damper can be arranged between the bracket lower flange and the steel beam lower flange and connected with the lower flange connecting plate in a sliding mode. And when the static force working condition or the small vibration acts, the internal force of the lower flange is completely born and transferred by utilizing the friction force between the plates, so that the sliding does not occur, the sufficient rigidity is provided for the structure, the rigid connection characteristic of the beam column connection node is ensured, and the sufficient lateral rigidity resistance of the steel frame is ensured. Under the action of middle earthquake and large earthquake, the plastic deformation of beam column joints is concentrated on the mild steel damper, the beam of the main structure is prevented from being damaged under the action of the earthquake, two ends of the damper core material are matched and inserted with wedge-shaped slots of the bracket lower flange and the steel beam lower flange through wedge-shaped cutting of the damper connector, the disassembly and assembly are convenient, and the repairing after the earthquake is easy.
However, the beam-column connecting joint has more plates for connecting brackets and steel beams, and comprises two web connecting plates, four first bottom flange connecting plates, a soft steel damper and two partition plates, and accordingly, the workload of hole site alignment at the bolt connecting position is increased, so that the field construction efficiency of the beam-column connecting joint is further reduced.
