A Restorable Assembled Seismic Shear Wall Structure

Abstract

A recoverable prefabricated anti-seismic shear wall structure. In the bottom wall of the shear wall structure with replaceable parts, the bottom conversion connection parts, high-performance filling blocks and slotted steel plates are set. The energy consumption in the bottom conversion connection parts The connecting steel plate can provide the tensile and shear bearing capacity of the structure, the high-performance infill block can provide the compressive and shear bearing capacity, and the slotted steel plate can supplement the shear bearing capacity; guarantee the lateral stiffness and shear capacity of the new shear wall Strength, when the bottom wall of the structure is damaged under strong earthquakes, the energy-dissipating connecting steel plates, high-performance filling blocks and slotted steel plates can be replaced to restore the structure to its original functional level after the earthquake; in addition , through the matching of four types of replaceable parts, replaceable parts and non-replaceable parts, the shear wall has four anti-seismic defense lines to ensure the seismic safety of the increased structure.

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...

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
