A prefabricated folded steel plate shear wall with two-sided connections and a plastic hinge guiding mechanism

Abstract

The invention discloses a two-side connection assembly type creased steel plate shear wall with a plastic hinge guiding mechanism. The two-side connection assembly type creased steel plate shear wall with the plastic hinge guiding mechanism comprises a steel plate composed of creased sub-units, and is connected with a frame beam by a bolt through two backward steel angles, wherein the sub-unit of the two-side connection assembly type creased steel plate shear wall with the plastic hinge guiding mechanism can be made of low-yield-point steel or common steel, a creased steel plate is formed of a common smooth steel plate through impact molding by specific equipment and the thickness of the creased steel plate can be determined according to the design requirements of the steel plate for the resistant-lateral rigidity and the ultimate bearing capacity; and besides, stiffening ribs having certain sizes are arranged at two sides of the two-side connection assembly type creased steel plate shear wall with the plastic hinge guiding mechanism. The two-side connection assembly type creased steel plate shear wall with the plastic hinge guiding mechanism has the advantages of high resistant-lateral rigidity and ultimate bearing capacity, good energy consumption performance and high ductility and the like, and is an excellent anti-knock component.

Description

technical field [0001] The invention belongs to the technical field of structural engineering, and in particular relates to a two-side-connected assembled crease steel plate shear wall with a plastic hinge guiding mechanism for lateral reinforcement. Background technique [0002] In recent years, my country's high-rise and super high-rise buildings have been greatly developed, and the steel plate shear wall structure has also been widely used in these buildings. In multi-story buildings, steel plate shear walls play an important role as the main anti-lateral force components. When an earthquake occurs, the steel plate shear wall will bear most of the earthquake action, ensure that the building is not damaged, and also absorb the energy during the earthquake. With the continuous increase of lateral load, the steel plates in ordinary steel plate shear wall structures are prone to out-of-plane buckling, resulting in poor energy dissipation performance and ductility.

AI Technical Summary

Problems solved by technology

However, some existing technologies use external components to achieve the purpose of anti-buckling and increased energy consumption, which not only makes the structure of the entire component more complicated and difficult to manufacture, but also increases the difficulty of construction

Some technologies adopt slits or openings on the steel plate, although it can increase its energy dissipation capacity and ductility, but it will greatly weaken the ultimate bearing capacity and lateral stiffness of the steel plate shear wall
