Description

A kind of stay cable type steel plate shear force wall
Technical field
The present invention relates to shear wall technical field, be specially a kind of stay cable type steel plate shear force wall.
Background technology
At present, adopt steel plate shear force wall to have building more than 20 as the building of main lateral resistant member in the world, be mainly distributed in the Areas of High Earthquake Intensity district such as North America and Japan.Since steel plate shear force wall is applied in building by Nippon Steel Corporation in 1970, existing more than 40 year of the development of steel plate shear force wall.Steel plate shear wall structure system is made up of embedded steel plate and edge member, and edge member comprises edge girder and edge posts.Embedded steel plate usually and edge member connect and compose lateral resisting structure system, this structural system can be considered the semi girder fixed on the ground.
According to the thickness of embedded steel plate, steel plate shear force wall can be divided into steel plate shear wall and thin steel plate shear wall; According to surface of steel plate whether ribbing, steel plate shear force wall can be divided into stiffening rib steel plate shearing force wall and non-stiffening rib steel plate shearing force wall; Whether crack according to surface of steel plate, steel plate shear force wall can be divided into slotted steel plate shear wall and not slotted steel plate shear wall; Whether arrange concrete slab according to steel plate side, steel plate shear force wall can be divided into steel plate-concrete combined shear wall and general steel plate shear wall.Although thin steel plate shear wall has good economic benefit, its easier flexing.Other forms of steel plate shear force wall mainly with stoping the deformity out of plane of steel plate to be target, allows steel plate keep as much as possible planar working to consume more energy greatly.
In China " Technical Specification for Steel Structure of Tall Buildings " (JGJ99-98), annex four specifies, for preventing steel plate shear force wall generation shear buckling, should using the shear buckling bearing capacity of steel plate as its ultimate bearing capacity, or make by putting more energy into steel plate its surrender before there is not flexing.In fact, above two kinds of modes are all partial to conservative and cost is higher, are unfavorable for development and the application of steel plate shear force wall.Along with domestic and international going deep into steel plate shear force wall research, the Post-bucklling behaviour of steel plate shear force wall obtains to be paid close attention to widely, and steel plate shear force wall still has higher bearing capacity, good ductility and stable energy dissipation capacity after flexing.The Post-Bucking Strength making full use of steel plate shear force wall not only can make structure obtain good anti-seismic performance, and significantly can reduce steel using amount, reduces cost, increases economic efficiency.
Traditional thin steel plate shear wall, when load is along a direction effect, embedded steel plate generation flexing also forms pull strap, is out of shape along with outside larger face; When external load acting in opposition, pull strap originally, by reverse pressurized, does not reoffer rigidity; Meanwhile, original pressurized zone will be transited into pulling force zone, but owing to once there is larger lateral deflection distortion under higher level's load, therefore have distortion to be stretched to the process of " open and flat ", until the formation of reversal interlocking relay band.In this course, steel plate cannot bearing load, and structure only bears external load by beam column, and because the support strength of beam column is lower, the pulling force field be anchored at like this on framework can produce larger additional bending moment to side column, adds the stable burden of pillar.And pillar is as the vertical bearing carrier of building, pillar needs a higher support strength, if destroyed, may cause collapsing of total, causes the dangerous factor.In addition, the defect that traditional steel plate shear force wall also exists can not steel plate wall punch, like this, in the architectural place needing opening holes exactly again, steel plate wall can not be used as lateral resistant member, thus reduce the range of application of steel plate wall as a kind of new type of component greatly.
Summary of the invention
The object of the present invention is to provide a kind of stay cable type steel plate shear force wall, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the invention provides following technical scheme: a kind of stay cable type steel plate shear force wall, comprise embedded steel plate and concrete frame, described embedded steel plate is steel sheet, described embedded steel plate two ends are welded with a bracing members post respectively, and described bracing members post upper and lower side is fixed on the upper and lower Vierendeel girder of described concrete frame by high-strength bolt; Have two through holes one on the other in the middle of described bracing members post, described prestressed cable passes from described through hole, should, described prestressed cable two ends are respectively by connection otic placode and be fixed on described upper and lower Vierendeel girder.
Preferably, the reinforcing bar in described connection otic placode and described upper and lower Vierendeel girder is fixing by being welded to connect, and is one overall by concreting.
Preferably, described concrete frame four interior angles are respectively equipped with deep floor.
Preferably, described deep floor is right angle triangle, and two vertical edges is welded on the reinforcing bar in described concrete frame respectively, and is an entirety by concreting.
Compared with prior art, the invention has the beneficial effects as follows: this stay cable type steel plate shear force wall, by arranging bracing members post and prestressed cable in shear wall both sides, can effectively limit steel plate wall deformity out of plane, improve the lateral resisting rigidity of steel plate wall, power consumption and ductile performance, simultaneously due to lightweight, do not increase the burden of structural column; Framework arranges deep floor, the support strength of framework can be effectively raised, make steel plate shear force wall more firm.
