One-way connecting column base node with additional lateral-resistance shearing wall and functions recoverable after earthquake

Abstract

The invention relates to a one-way connecting column base node with an additional lateral-resistance shearing wall and functions recoverable after an earthquake, and belongs to the field of structuralengineering. The node is composed of a square steel column, a one-way pure hinge base and replaceable lateral-resistance energy-consumption devices which are arranged on the two sides. According to the node, designing concepts of damage control, replaceable energy-consumption members, moment modification, vertical bearing, horizontal lateral-resistance separation and the like are applied, and theadvantages of traditional rigid connection columns and traditional hinge columns are combined. The moment modification is achieved through reasonable designing to reduce on-column bending moment, sothat the node is protected from damaging, primary lateral-resistance operation is undertaken by the replaceable lateral-resistance energy-consumption devices, and the damage on the node is avoided through a 'strong node' manner. The functions of the column base node can be recovered by simply replacing the lateral-resistance energy-consumption devices after the earthquake.

Description

technical field [0001] The invention relates to a post-earthquake recoverable function one-way hinged column base node of an additional lateral shear wall, 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. In September 2016, the State Council issued a document to vigorously develop prefabricated buildings, and the proportion of prefabricated buildings will reach 30% in about 10 years. 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 ...

AI Technical Summary

Problems solved by technology

[0006] The present invention proposes a one-way hinged post-seismic post-seismic post-recoverable post-seismic joint with an additional lateral shear wall, aiming to solve the problem of relatively large post-seismic damage to the bottom post and difficult post-seismic repairs in the existing prefabricated 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
