Shear wall with dense ribs and clad steel plates

Abstract

The invention discloses a composite steel plate shear wall with dense ribs, which comprises a plurality of rib beams and rib columns, the plurality of rib beams and rib columns form a rectangular grid structure, each grid is provided with an embedded steel plate; a plurality of ribs Beams and rib columns are all made of reinforced concrete, reinforced concrete or all steel; multiple embedded steel plates are ordinary low carbon steel, high strength steel, low yield point steel or low yield strength aluminum; multiple embedded steel plates are in the form of All are rectangular plates, rectangular plates with vertical slits and round holes, X-shaped plates and strip plates. By changing the number of slits, aperture size, arc size and width of the steel plate, the ductility of the steel plate shear wall can be easily adjusted And rigidity, thereby improving the mechanical performance of the overall structure, it is a superior earthquake-resistant lateral force member. The invention can prevent the buckling of the steel plate, the embedded steel plate can be adjusted, the anti-seismic performance is good, the construction and installation are convenient, the steel material is saved, the cost is low, and it is easy to implement. .

Description

technical field [0001] The invention belongs to the field of anti-seismic technology of building structures, and in particular relates to a dense rib composite steel plate shear wall. Background technique [0002] The frame-shear wall structure is a structural form widely used in my country. The traditional frame-shear wall structure is composed of a reinforced concrete frame and a certain number of reinforced concrete shear walls. However, a series of post-earthquake survey statistics in recent years show that the reinforced concrete The effect is not good during an earthquake, and it is completely or mostly damaged after the earthquake, and cannot be repaired and reinforced, thereby greatly increasing the post-earthquake reconstruction workload. For this reason, countries such as the United States, Japan, and Canada have developed a new type of lateral force-resisting structure system embedded steel plate shear wall structure, which is formed by a certain number of embedd...

AI Technical Summary

Problems solved by technology

Therefore, the segmented unbonded buckling-resistant steel plate shear wall still cannot fundamentally solve the problems of fabrication, construction, transportation and installation of this type of wall

In summary, most of the existing technologies have major problems such as easy buckling and instability, difficult construction, heavy weight, high cost, and difficult implementation, which have affected their popularization and application in engineering practice.
