Description

A kind of pre-stressed steel plate shear wall
Technical field
The present invention relates to a kind of novel pre-stressed steel plate shear wall, belong to technical field of structural engineering.
Technical background
At present, adopt in the world steel plate shear force wall to have building more than 20 as the building of main lateral resistant member, be mainly distributed in the Areas of High Earthquake Intensity district such as North America and Japan.Since Nippon Steel Corporation in 1970 is applied in building by steel plate shear force wall, 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 conventionally and edge member connect and compose lateral resisting structure system, this structural system can be considered the semi girder fixing 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 whether ribbing of surface of steel plate, 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 slotted steel plate shear wall not; 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 is target mainly with the deformity out of plane that stops steel plate greatly, allows steel plate keep as much as possible planar working to consume more energy.
China's " Technical Specification for Steel Structure of Tall Buildings " JGJ(99-98) in appendix four stipulate, for preventing steel plate shear force wall generation shear buckling, should be using the shear buckling bearing capacity of steel plate as its ultimate bearing capacity, or make by steel plate is put more energy into, before its surrender, flexing does not occur.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 both at home and abroad, to the going deep into of steel plate shear force wall research, after the flexing of steel plate shear force wall, performance has obtained paying 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 that makes full use of steel plate shear force wall not only can make structure obtain good anti-seismic performance, and can significantly reduce steel using amount, reduces cost, increases economic efficiency.
Summary of the invention
The present invention proposes a kind of novel pre-stressed steel plate shear wall, its object is, overcome thin steel plate shear wall and can not give full play to the shortcoming of the strength and ductility of steel because of too early flexing, improved flat lateral stability and the ultimate bearing capacity of steel plate shear force wall, given full play to the advantage of steel.
Do not establish the thin steel plate shear wall that prestressing force supports, when load is during along a directive effect, embedded steel plate generation flexing also forms pull strap, is accompanied by larger face and is out of shape outward; In the time of external load acting in opposition, pull strap originally, by reverse pressurized, no longer provides rigidity; Meanwhile, original pressurized zone will be transited into pulling force zone, but due to larger lateral deflection distortion once occurring under higher level's load, be out of shape the process that is stretched to " open and flat ", until the formation of reversal interlocking relay band therefore have.In this course, steel plate cannot bearing load, and structure only depends on beam column to bear external load, and the pulling force field being anchored at like this on framework can produce larger additional bending moment to side column, has increased the stable burden of pillar.So the setting that prestressing force supports, has limited the larger deformity out of plane after embedded steel plate flexing on the one hand, and lateral restraint is provided; Two on the one hand, and when load reversal does the used time, prestressing force supports can bear external load effect, avoids increasing the burden of beam column.
The pre-stressed steel plate shear wall that the present invention proposes, is characterized in that, described pre-stressed steel plate shear wall is made up of embedded steel plate, prestressed cable, support otic placode, connection otic placode and edge member; Described steel plate adopts steel sheet; Described prestressed cable adopts common prestress wire; Described support otic placode is the support vertical with steel plate surface that can reeve with holes; Described connection otic placode is the end otic placode of fixing prestressed cable; Described edge member is respectively edge posts and edge girder; Described embedded steel plate is connected with described support otic placode; Described embedded steel plate connects with the described otic placode that is connected; Described embedded steel plate is connected with edge posts and edge girder; Described prestressed cable is through described support otic placode; Described prestressed cable is fixed on described connection otic placode.
In above-mentioned pre-stressed steel plate shear wall, described embedded steel plate adopts the high ductility steel of low-yield or the high ductility steel of high strength.
In above-mentioned pre-stressed steel plate shear wall, described embedded steel plate adopts welding or bolt to connect with described support otic placode and the described otic placode that is connected.
In above-mentioned pre-stressed steel plate shear wall, described embedded steel plate be divided into two kinds being connected of edge member, the first and edge member all weld, its two be only with the welding of described edge girder.
In above-mentioned pre-stressed steel plate shear wall, described prestressed cable is fixed on described connection otic placode through described support otic placode.
In above-mentioned pre-stressed steel plate shear wall, described prestressed cable, described support otic placode and described connection otic placode are arranged in described embedded steel plate bilateral symmetry.
The present invention by both side surface, otic placode and prestressed cable being installed, can effectively limit steel plate wall deformity out of plane to traditional thin steel plate shear wall, improves anti-side rigidity, power consumption and the ductile performance of steel plate wall.Traditional steel plate shear force wall is the flat lateral stability of controlling steel plate shear force wall by stiffening rib is set on steel plate, belong to passive control method, the present invention on steel plate shear force wall initiatively apply prestressing force, control the flat lateral stability of steel plate shear force wall, simultaneously, prestressed cable can be born certain pulling force in the pull strap direction of steel plate shear force wall, belongs to control method initiatively.All members of this invention can be in factory process, and then, in assembling on the spot, construction is simple, reduces cost, is applicable to assembling type steel structure.
The novel lateral resistant member of one that pre-stressed steel plate shear wall provided by the invention is high-rise building steel structure or other structure.
