Problems solved by technology
[0005] The present invention proposes a new type of prestressed slotted steel plate shear wall, the purpose of which is to overcome the shortcomings of thin steel plate shear walls that cannot give full play to the strength and ductility of steel due to premature buckling, and improve the performance of steel plate shear walls. Out-of-plane stability and ultimate bearing capacity, giving full play to the advantages of steel

A prestressed slotted steel plate shear wall belongs to the technical field of structural engineering. The prestressed slotted steel plate shear wall includes embedded slotted steel plates, prestressed members, connecting ear plates, brackets, edge members, frame beams and frame columns. The slotting form of the embedded slotted steel plate can be horizontal or vertical slotted; the embedded slotted steel plate is connected with the edge member with bolts; The inlaid seam steel plates are symmetrically arranged on both sides; the vertical edge members are welded to the horizontal edge members; the connecting lugs are symmetrically arranged on the flange of the frame beam and welded to the frame beam; the horizontal edge members are welded or bolted to the frame beam; the brackets are connected to the vertical edge Components and embedded slotted steel plates are welded; frame beams and frame columns are welded or bolted or bolted and welded. The invention is a novel lateral force-resisting component of a high-rise building structure or other structures, which has the characteristics of good seismic performance, high ductility, full energy-dissipating hysteresis loop and the like.
Description
technical field [0001] The invention relates to a novel prestressed slotted steel plate shear wall, which belongs to the technical field of structural engineering. Background technique [0002] At present, there are more than 20 buildings in the world that use steel plate shear walls as the main anti-lateral force components, and they are mainly distributed in areas with high seismic intensity such as North America and Japan. Since Japan Steel Corporation applied steel plate shear walls to buildings in 1970, the steel plate shear walls have been developed for more than 40 years. The steel plate shear wall structural system consists of embedded steel plates and edge members, and the edge members include edge beams and edge columns. Embedded steel plates are usually connected with edge members to form a lateral force resistant structural system, which can be regarded as a cantilever beam fixed on the ground. [0003] According to the thickness of the embedded steel plate, th...
