Post-earthquake function-recoverable one-way hinge column foot joint with additional anti-shear steel plate group

Abstract

The invention relates to a post-earthquake function-recoverable one-way hinge column foot joint with an additional anti-shear steel plate group, and belongs to the field of structural engineering. Thejoint 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 replaceable anti-side energy consuming devices undertake main anti-side work, and damage is controlled to the anti-shear steel plate group through a strong-joint and weak-member mode. Afteran earthquake, the functions of the column foot joint can be recovered simply by replacing the anti-side energy consuming devices.

Description

technical field [0001] The invention relates to a post-earthquake recoverable one-way hinged column base node with an additional shear steel plate group, 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...
