Wavy steel plate shear wall

Abstract

The invention relates to a novel wavy steel plate shear wall belonging to the technical field of structural engineering. The wavy steel plate shear wall consists of a wavy steel plate, a transitional fishplate and an edge component, wherein the wavy steel plate adopts low-yield-point high-ductility steel or high-strength high-ductility steel, is molded by rolling a common flat steel plate through specific equipment, and can be small in thickness; the fishplate is divided into two types, namely a flat straight fishplate and a wavy fishplate, adopts high-ductility steel, has the thickness between the thickness of a beam column flange and that of a shear-wall steel plate, and plays a role in transition; the fishplate and a beam column are in welded connection; and the wavy steel plate and the fishplate are in welded connection. The wavy steel plate shear wall has the advantages of high capacity of resisting side force, good anti-seismic performance, high ductility, full energy-dissipation hysteretic ring and the like, and is an excellent seismic-energy dissipation component.

Description

technical field [0001] The invention relates to a novel corrugated steel plate shear wall, which belongs to the technical field of structural engineering. technical background [0002] As lateral force-resisting components of multi-story steel structures, thick steel plate shear walls and medium-thick steel plate shear walls have better lateral stiffness and energy dissipation characteristics, but are rarely used in engineering design due to their high cost. [0003] Although the thin steel plate shear wall has good economic benefits, the local buckling load of the steel plate under the shear force is very low, and the lateral stiffness is mainly provided by the tension band formed after the steel plate buckles. Its main disadvantages are: (1) The tension band formed after the buckling of the steel plate is anchored on the frame beam and column, and the unfavorable effect of the anchor force on them should be considered when designing the beam and column. (2) The hysteretic...

[0003] Although the thin steel plate shear wall has good economic benefits, the local buckling load of the steel plate under the shear force is very low, and the lateral stiffness is mainly provided by the tension band formed after the steel plate buckles. Its main disadvantages are: (1) The tension band formed after the buckling of the steel plate is anchored on the frame beams and columns, and the adverse effect of the anchoring force on them should be considered when designing the beams and columns

(2) The hysteretic curve of the thin steel shear wall under repeated loads has a relatively serious pinching phenomenon, which is not conducive to the consumption of the energy input by the earthquake with the steel plate

(3) Under the action of repeated loads, the thin steel plate shear wall repeatedly drums along the surface, which will produce a huge drumming sound, causing panic

Especially under the action of frequent wind loads, there will be a crackling sound, which is not conducive to the promotion and application in engineering
