Shear wall composed of multilayer steel plates

Abstract

The invention discloses a shear wall composed of multilayer steel plates, belonging to the technical field of structural engineering. The shear wall is characterized in that plain steel plates and the corrugated steel plates are combined in a laminating manner to form a shear wall combined of double-layer steel plates; or a plain steel plate is clamped between two corrugated steel plates to form a shear wall combined of three-layer steel plates; a thin-layer hard rubber pad is arranged between the plain steel plate and the corrugated steel plate; the plain steel plate, the corrugated steel plate and the thin-layer hard rubber pad are connected through a high-strength bolt; the pretightening force of the high-strength bolt enables the frictional force to be generated between the plain steel plate and the corrugated steel plate, thus the plain steel plate and the corrugated steel plate are commonly applied force under the action of the lateral force; under the action of strong earthquake, the relative slippage is generated because of larger displacement difference value inside the surfaces of the plain steel plate and the corrugated steel plate, and the plain steel plate and the corrugated steel plate are mutually restrained outside the surface all the time; and the plain steel plate and the corrugated steel plate are connected with the surrounding edge constructional members through C-shaped steel. The shear wall combined of multilayer steel plates can be used as a novel lateral force resistant constructional member in a high-rise building steel structure or other structures.

Description

technical field [0001] The invention relates to a multi-layer steel plate combined shear wall, which belongs to the technical field of structural engineering. Background technique [0002] Steel plate shear wall is a new type of high-rise anti-lateral force structural system. Compared with the traditional reinforced concrete shear wall, the steel plate shear wall has the advantages of matching the rigidity and ductility of the steel frame and the effective play of the strength after buckling, which establishes the foundation as the main anti-lateral force unit in the design of steel frame structures. However, the ductility of reinforced concrete shear walls basically disappears after the concrete cracks, which is not conducive to the application of buildings in high fortification seismic intensity areas. Especially under the action of moderate or large earthquakes, the high ductility exhibited by the steel plate shear wall can greatly reduce the earthquake action and action...

AI Technical Summary

Problems solved by technology

The flat steel plate shear wall is easy to buckle under the in-plane shear force, and the lateral stiffness is provided by the tension band after buckling; especially when the steel plate is relatively thin, the shear buckling load of the flat steel plate shear wall is low, and the buckling forms a tensile force The hysteretic curve after stripping shows a serious pinching phenomenon. Although the thick steel plate shear wall is not easy to buckle and has good hysteretic energy dissipation performance, the amount of steel is large and the economic benefit is poor; Under the action of force, it has high initial shear buckling load and lateral stiffness, but the corrugated steel plate is a defect-sensitive component. After it reaches the ultimate bearing capacity, the bearing capacity of the plate decreases rapidly as the wave surface is flattened. Its hysteresis performance is not very ideal
