A prefabricated ribbed steel plate-shear wall

Abstract

The invention discloses an assembly-type ribbed steel plate-shear wall. The problems of poor anti-seismic property and repairing difficulty are solved. The assembly-type ribbed steel plate-shear wallcomprises assembly-type ribbed steel plates, connection plates, frame steel beams and frame columns. The assembly-type ribbed steel plates are connected through bolts, and the assembly-type ribbed steel plates are connected with the frame steel beams through the connection plates and bolts; the frame columns are connected with the frame steel beams but not connected with the assembly-type ribbed steel plates. The prefabrication assembly degrees of all components of the assembly-type ribbed steel plate-shear wall are greatly improved, the anti-seismic property is improved, and meanwhile the assembly-type ribbed steel plate-shear wall is easy to mount, transport and repair and suitable for being widely applied to buildings with walls such as shock-proof walls.

Description

technical field [0001] The invention belongs to the technical field of building structures, and in particular relates to an assembled ribbed steel plate-shear wall. Background technique [0002] The steel plate shear wall has strong ductility, energy dissipation capacity, and superior seismic performance. It is suitable for high-intensity earthquake areas and has become a high-rise lateral force resistant system with development prospects. The frame shear wall is a shear wall with frame columns and frame beams, and its seismic capacity is significantly improved compared with ordinary shear walls. The frame beams and frame columns together form a restraint effect on the wall, delaying the occurrence of cracks, thereby improving the mechanical performance of components. [0003] Due to the large width and thickness ratio of the traditional thin steel plate shear wall, the steel plate is prone to local buckling under the action of lateral force, and even a large out-of-plane d...

AI Technical Summary

Problems solved by technology

[0003] Due to the large width and thickness ratio of the traditional thin steel plate shear wall, the steel plate is prone to local buckling under the action of lateral force, and even a large out-of-plane deformation will occur, resulting in the insufficient strength and ductility of the steel. The advantages of the steel plate shear wall cannot fully reflect

The traditional form of wall panel connection is the welded connection between the wall panel and the fishplate, and the fishplate is welded to the frame beam and frame column. However, after a strong earthquake, the embedded steel plate and connectors cannot be replaced for the damaged beam end nodes. cause some economic loss

The tension band formed along the diagonal direction in the steel plate shear wall causes a large additional bending moment in the frame column, which may cause premature failure of the frame column and seriously affect the full play of the seismic performance of the steel plate shear wall
