Abstract

The invention discloses an anti-buckling steel plate seismic shear wall provided with stiffening ribs. The anti-buckling steel plate seismic shear wall comprises a steel plate wall, horizontal stiffening ribs, vertical stiffening ribs, steel columns and steel girders, wherein the steel plate wall is arranged in a frame formed by the steel columns and the steel girders, and the multiple horizontal stiffening ribs are uniformly fixed on two side wall surfaces of the steel plate wall at vertical intervals and horizontally welded on the steel plate wall; the multiple vertical stiffening ribs are fixed between the horizontal stiffening ribs at horizontal intervals and are vertically arranged, and upper ends and lower ends of the vertical stiffening ribs are welded with the horizontal stiffening ribs; a gap is reserved between each vertical stiffening rib and the steel plate wall. According to the anti-buckling steel plate seismic shear wall provided with the stiffening ribs, overall buckling and local buckling of the steel plate wall can be prevented, so that the steel plate wall can only yield, and the shear capacity and the severe earthquake energy dissipation performance of the steel plate wall are improved; the anti-buckling steel plate seismic shear wall is simple in structure and reasonable in stress, can bear horizontal force under the action of the earthquakes, and is convenient to construct and high in degree of industrialization.

Description

technical field [0001] The invention relates to an anti-seismic wall of a buckling-resistant steel plate with stiffening ribs, which belongs to the technical field of building structure engineering and can be widely used in lateral force-resistant systems of various steel structure buildings. Background technique [0002] In the steel structure of high-rise buildings, the anti-lateral force systems used to resist horizontal forces such as wind loads and earthquakes mainly include concrete shear walls, steel supports, and steel plate shear walls. [0003] The concrete shear wall is used together with the steel structure, which is a hybrid structure. Relying on the concrete shear wall to provide lateral stiffness and withstand horizontal force, the requirements for the lateral movement of the structure are strict, and the advantages of the steel structure's good lateral ductility cannot be brought into play. [0004] The steel support has good lateral force resistance performa...
