Fabricated anti-seismic shear wall structure capable of recovering functions

Abstract

The invention provides a fabricated anti-seismic shear wall structure capable of recovering functions. A bottom layer conversion connecting part, a high-performance filling block body and a slotted steel plate are arranged in a bottom layer wall body of the shear wall structure capable of replacing parts, an energy-consuming connecting steel plate in the bottom layer conversion connecting part can provide tensile and shear bearing capacity for the structure, the high-performance filling block body provides compression and shear bearing capacity, and the slotted steel plate can complementally and provide the shear bearing capacity. Resistant-lateral rigidity and strength of a novel shear wall are guaranteed, and when the bottom wall body of the structure is damaged under the action of a strong earthquake, the structure can recover to the original function level after the earthquake by replacing the energy-consuming connecting steel plate, the high-performance filling block body and the slotted steel plate; and in addition, through four types of replaceable parts and matching of the replaceable parts and non-replaceable parts, the shear wall has four anti-seismic defense lines, and it is guaranteed that the anti-seismic safety of the structure is improved.

Description

technical field [0001] The invention belongs to the field of recoverable function structures, and in particular relates to a recoverable function assembled anti-seismic shear wall structure. Background technique [0002] The recoverable functional structure with replaceable parts is a new type of structure developed in recent years. After the earthquake, the structure can quickly restore its normal function through the replacement of components. [0003] Shear walls are widely used in high-rise buildings as the main lateral force-resisting components, and their seismic performance and post-earthquake recovery ability are critical to the overall seismic performance of buildings. Replaceable coupling beams and replaceable wall feet are common forms of replaceable component shear walls. The design concept is to design the coupling beams and wall foot parts of traditional monolithic shear walls as replaceable structural components. Compared with the traditional cast-in-place s...

AI Technical Summary

Problems solved by technology

[0004] In common shear walls with replaceable parts, all parts of the wall except the replaceable parts are integrally poured, which requires a lot of wet work on site, which consumes a lot of man-hours and manpower; and the connection structure used to connect the replaceable parts requires Pre-buried into the wall, it is difficult to ensure its positioning accuracy in on-site operations

In addition, due to the uncertainty of the seismic action intensity, the concrete of the common replaceable foot shear wall will suffer from severe crushing in the pouring area near the replaceable part at the bottom of the wall under a large interstory displacement angle. Damage to the concrete in the bottom monolithic area can lead to a reduction in the overall performance of the replaceable foot shear wall and is not easy to repair
