Problems solved by technology

[0003] Under the large load of the existing steel plate shear wall, the embedded steel plate is destroyed first, then the frame beam or the connection node between the frame beam and the frame column is destroyed, and finally the frame column is destroyed. In this failure mode , the connection nodes between frame beams and frame columns and the damage of frame beams have great uncertainty, and the connection nodes between frame beams and frame columns often fail preferentially, and their lateral force and energy dissipation performance is insufficient, so that Seriously affect the reliability, safety and service life of the entire steel plate shear wall structure. Most steel plate shear walls are prone to local buckling under the action of lateral force due to their large thick plates, and will produce tension bands. A lot of welding work

Abstract

The invention discloses a prefabricated steel plate shear wall system with two anti-seismic defense lines, and relates to the field of structural engineering. According to the technical scheme, two double-limb spliced cap type cold-formed thin-walled section steel columns or two welding closed cold-formed thin-walled section steel columns with extending ends are connected with two cold-formed thin-walled section steel beams to form a rectangular frame, an embedded steel plate is fixed in the rectangular frame through a plurality of self-tapping screws, and X-shaped cable-stayed steel belt setsor prefabricated mortar plates with decoration bars are arranged on the two sides of the rectangular frame. The prefabricated steel plate shear wall system with the two anti-seismic defense lines ishigh lateral stiffness, and the two anti-seismic defense lines are provided, so that the system has extremely high earthquake energy dissipation performance and excellent anti-seismic performance; andthe self-tapping screws or bolts are adopted for connection, prefabricated construction is convenient and fast, and the application prospect in the fields of multi-layer steel structure building earthquake resistance and industrial prefabricated structures is wide.

Description

technical field [0001] The invention relates to the field of structural engineering, in particular to an assembled cold-formed thin-walled steel structure. Background technique [0002] Cold-formed thin-walled steel structure is a new type of structural system widely used in Europe and the United States. Because the cold-formed thin-walled structure is easy for factory processing, on-site assembly construction and installation, short construction period, steel can be recycled, and has good economic benefits, it is in line with The design concept of green building has a great application prospect in the multi-storey residential building system. [0003] Under the large load of the existing steel plate shear wall, the embedded steel plate is destroyed first, then the frame beam or the connection node between the frame beam and the frame column is destroyed, and finally the frame column is destroyed. In this failure mode , the connection nodes between frame beams and frame col...
