Description
Technical field
The present invention relates to a kind of novel assembling 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 " (JGJ99-98) middle appendix four stipulates, 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 assembling 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, flat lateral stability and the ultimate bearing capacity of steel plate shear force wall are improved, give full play to the advantage of steel, and this novel fabricated steel plate shear force wall can be realized in factory process, transporting to field by using bolt is connected with Vierendeel girder, avoid wet trade and welding, can realize industrialization and modularization, reduce the duration, cost-saving.
Traditional thin steel plate shear wall, 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.And pillar is as the vertical bearing carrier of building, if destroyed, may cause collapsing of total.In addition, the defect that traditional steel plate shear force wall also exists punches on steel plate wall exactly again, like this, and in the architectural place that needs opening holes, can not use steel plate wall as lateral resistant member, thereby reduce greatly the range of application of steel plate wall as a kind of new type of component.This novel fabricated steel plate shear force wall arranges edge member in shear wall surrounding, and only horizontal edge member is connected with Vierendeel girder.Like this, the setting of edge member, has limited the larger deformity out of plane after embedded steel plate flexing on the one hand, and lateral restraint is provided; On the other hand, when load reversal does the used time, edge member can bear external load effect, avoids increasing the burden of pillar.In surrounding, edge member is set, can reduces like this after wallboard and pillar disengagement the amplitude of endurance and stiffness and depression of bearing force.And this novel fabricated steel plate shear force wall, the defect of having avoided conventional steel plates shear wall not punch, so can well be applied in many high-rise steel structure as lateral resistant member.
The assembling steel plate shear wall that the present invention proposes, is characterized in that, described assembling steel plate shear wall is made up of embedded steel plate, vertical edge member, horizontal edge member, high-strength bolt, L shaped junction plate, frame column and Vierendeel girder; Described embedded steel plate adopts steel sheet; Described vertical edge member, horizontal edge member adopt T framework; Described L shaped junction plate is the steel plate in strap bolt hole; Described embedded steel plate is connected with vertical edge member and horizontal edge member; Described horizontal edge member is connected with Vierendeel girder; Described vertical edge member is connected by L shaped junction plate with horizontal edge member.Described Vierendeel girder is connected with frame column.
In above-mentioned assembling steel plate shear wall, described embedded steel plate adopts the high ductility steel of low-yield or the high ductility steel of high strength.And four bight cuttings, facilitate the connection between edge member.
In above-mentioned assembling steel plate shear wall, described embedded steel plate is divided into two kinds with being connected of vertical edge member, horizontal edge member, and the first and edge member all weld, and it two is to be connected with edge member bolt, and this entirety completes in factory process.
In above-mentioned fabricated shear wall, described vertical edge member is being connected by L shaped junction plate bolt with described horizontal edge member.
In above-mentioned fabricated shear wall, described high-strength bolt is arranged symmetrically with at position, the described Vierendeel girder edge of a wing.
