Post-earthquake function-recoverable one-way hinge column foot joint with additional inclined anti-side BRBs

Abstract

The invention relates to a post-earthquake function-recoverable one-way hinge column foot joint with additional inclined anti-side BRBs, and belongs to the field of structural engineering. The joint is composed of a square steel column, a one-way pure hinge base and replaceable anti-side energy consuming devices on both sides. The joint applies design concepts of damage control, energy consuming component replacement, bending moment amplitude modulation, vertical bearing, horizontal anti-side separation and the like, and combines the advantages of traditional rigid connection columns and traditional hinge columns. Through the reasonable design, bending moment amplitude modulation is achieved, and the bending moment on the column is reduced to protect the column against damage; meanwhile, the BRBs undertake main anti-side work to control the damage to the BRBs. The two ends of each BRB are hinged, the energy consuming performance of the BRBs is fully exerted by converting lateral load into axial load applied to the BRBs, and the working efficiency of anti-side energy consuming components is improved. After an earthquake, the functions of the column foot joint can be recovered simplyby replacing the BRBs.

Description

technical field [0001] This patent relates to a post-earthquake recoverable one-way hinged column base node with an additional oblique anti-lateral BRB, which belongs to the technical field of structural engineering. Background technique [0002] Industrialized prefabricated steel structure is an inevitable trend in the development of high-rise steel structure residential buildings in the future, and it is the only way for my country to realize the industrialization of construction. Prefabricated buildings are a major change in construction methods and an important measure to promote structural reforms and new urbanization development. They are fully in line with the connotation of "applicability, efficiency, coordination and development" of green buildings. Building assembly can standardize each component, the factory produces uniform specifications, and bolts are assembled accurately on site to avoid the consumption of building materials caused by construction errors, and ...

AI Technical Summary

Problems solved by technology

[0006] The present invention proposes a one-way hinged post-seismic post-seismic recoverable post-seismic joint with an additional oblique anti-lateral BRB, aiming to solve the problem of large post-seismic damage to the bottom column and difficulties in post-seismic repairs in the existing assembled steel structure system. Disadvantages, avoiding waste of steel, prolonging the service life of nodes, improving economic benefits, and also providing more options for the assembled bottom column foot nodes
