Embodiment Construction

[0015] The present invention is described in detail below in conjunction with accompanying drawing:

[0016] like figure 1 , 2 As shown, 1-left edge column, 2-right edge column, 3-upper edge beam, 4-lower edge beam, 5-embedded steel plate, 6-concrete cover plate, 7-reserved ellipse on concrete cover plate Holes, 8-connecting bolts between the embedded steel plate and the concrete cover, 9-reserved gap between the concrete cover and the frame,

[0017] The anti-buckling steel plate wall of the present invention is composed of embedded steel plates, steel plate front and rear restraint concrete cover plates and edge components; the edge components are composed of left and right edge columns 1, 2 and upper and lower edge beams 3, 4, and the embedded steel plates 5 are low yield point high ductility steel or high strength high ductility steel; the front and rear concrete cover plates 6 are made of general concrete plates; Open elliptical holes 7 on the concrete cover plate 6 so...

Abstract

The invention involves a kind of data organization project area of technology to guard against the flexure to consume energy the steel plate shearing force wall. Its characteristic causes to state the shearing force wall to inlay the steel plate and two sides periphery concrete lap by in is composed; In states inlays the steel plate to use the low yield point high ductility steel products or the high strength high ductility steel products; States the periphery concrete lap to use the common concrete slab; States the edge component is composed by the marginal beam and the edge column; In states inlays the steel plate with to state between the concrete lap through to penetrate three blocks the bolts or the pre-stressed bold fastening, in states on the concrete lap to open the ellipse hole in order to the bolt passed through also has the enough slipping space; In states the concrete lap to open the hole site with to bury the trough section to give strengthens. And is strengthening the channel steel the corresponding position to open oval hole. The invention provides guards against the flexure steel plate shearing force wall is the high-rise construction structure or other structures a kind of new anti- lateral force components, it has the earthquake resistance performance well, the ductility is high, consumes energy stagnates winds full and so on the characteristic, is a kind of superior earthquake resistance consumes energy the component.

Description

technical field [0001] The invention relates to a novel lateral force-resistant and buckling-resistant energy-consuming steel plate shear wall, which belongs to the technical field of structural engineering. Background technique [0002] Steel plate shear wall, as a new type of lateral force-resisting member, has been widely used in western developed countries such as the United States, Japan and Canada, and has begun to be used in high-intensity seismic fortification areas in my country in recent years. Compared with the reinforced concrete shear wall, the steel plate shear wall has better energy dissipation capacity and better ductility, and overcomes the shortcomings of the concrete shear wall that the concrete cracks and the ductility is greatly reduced under the action of a large earthquake. It is a kind of Superior seismic energy-dissipating components; however, when designing steel plate shear walls, it is necessary to adopt a smaller aspect ratio or set a strong stif...
