Description

A prefabricated recycled concrete buckling-resistant steel plate shear wall

technical field

The utility model relates to the technical field of assembled buildings, in particular to an assembled recycled concrete anti-buckling steel plate shear wall.

Background technique

Prefabricated buildings are buildings assembled on site with prefabricated components, mainly including prefabricated concrete structure buildings, steel structure buildings, modern wood structure buildings, etc. The prefabricated building adopts standardized design, factory production, assembly construction, information management and intelligent application, and transfers a large number of on-site operations in the traditional construction method to the factory. It is a modern industrial production method.

Steel structure has the advantages of light weight, high degree of industrialization, recyclability, green energy saving and good seismic performance, and is a natural assembly building material. In recent years, steel plate shear walls have been used in practical engineering projects as excellent lateral members. Steel plate shear wall is prone to out-of-plane buckling under the action of horizontal load. In order to restrain the out-of-plane displacement of the steel plate, a buckling-resistant steel plate shear wall has appeared. The main feature is that the fish plate connects the steel plate and the steel frame together. The tail plate is mainly connected to the steel frame through welds. However, there will be welding residual stress at the weld. When the steel plate shear wall is damaged, the weld joint often becomes a weak link due to weld defects, and then node failure occurs, and the failure mode is brittle failure.
