Description

Outer sticking steel plate-the combined concrete shear wall of a kind of prestressing force
Technical field
The present invention relates to the outer sticking steel plate-combined concrete shear wall of a kind of novel prestressing force, belong to technical field of structural engineering.
Background technology
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.
In China's " Technical Specification for Steel Structure of Tall Buildings " JGJ99-98, annex four specifies, 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 the outer sticking steel plate-combined concrete shear wall of a kind of novel prestressing force, 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, improve 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 pulling force supports, in the time of load action, steel plate generation flexing also forms pull strap, 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 pulling force supports, can bear external load effect, avoids increasing the burden of pillar.The setting of the outer sticking steel plate of embedded concrete slab, makes body of wall can give full play to its shear-carrying capacity.And steel plate wall is only connected with Vierendeel girder, because wallboard needn't connect whole section of girder span, the defect of therefore having avoided four limit junction steel plate walls not punch, and in surrounding, edge member is set, can reduce like this after wallboard and pillar disengagement the amplitude of endurance and stiffness and depression of bearing force.So can well be applied in many high-rise steel structure as lateral resistant member.
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 shear wall initiatively apply prestressing force, control the flat lateral stability of shear wall, simultaneously, prestressed cable or prestressed draw-bar can be born certain pulling force in the pull strap direction of shear wall, belong to control method initiatively.And shear wall is only connected with structural beams, avoids increasing the burden of structural column.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 clean steel board wall time, just there is cripling in steel sheet under smaller load action, produces larger in-plane deformation, and therefore hysteresis loop shows and significantly pinches phenomenon, and the energy dissipation capacity of steel plate can not be fully played.
Embedded steel plate and one-sided steel plate combined shear wall are applied to building structure group and will have the following disadvantages: 1, because concrete is positioned at steel plate outside, the in the situation that of large deformation, may there is cracking and peel off in concrete slab, effect of contraction to steel plate weakens greatly, and the ductility energy dissipation capacity of shear wall under large shake effect significantly reduced; 2, the more difficult control of concrete cracking, crack is exposed and is difficult to avoid, and uses and durability thereby impact is normal.Outer sticking steel plate-the combined concrete shear wall of prestressing force that the present invention proposes, one of effective way addressing the above problem: within 1, concrete slab is embedded in outside steel plate, can play effect of contraction to steel plate all the time, and outside steel plate is to the same Constrained effect of embedded concrete, thereby improve the deformability of embedded concrete slab, ductility and the energy dissipation capacity of shear wall under large shake effect significantly improved; 2, double steel plate-combined concrete shear wall simple structure, steel work easy transportation and installation, construction is simple; 3, outside steel plate can effectively avoid distress in concrete to expose; 4, the outer sticking steel plate-combined concrete shear wall hysteresis loop form of prestressing force is full, shows stronger ductility and energy dissipation capacity, has superior anti-seismic performance.
