The shear wall is formed by assembling steel pipe concrete frame columns (1) and a concrete shear wall board with an embedded steel plate (2), and is characterized in that the steel pipe concrete frame columns (1) are arranged at two ends of the shear wall, a profile steel beam (4) is arranged on a frame beam, and a steel support (3) is arranged on the steel plate (2) embedded in the shear wall. Compared with shear walls of the prior art, the shear wall provided by the utility model has the advantages of larger initial rigidity, greater load-bearing capacity, slower bearing capacity and rigidity attenuation, better overall shock resistance and energy consumption performance, relatively stable shock resistance performance at the later stage, and less shear slip damage at the bottom part.
Description
Technical field
The utility model relates to a kind of steel tube concrete-steel support-steel plate external wrapping concrete shear force wall, belongs to the seismic design of structures field.
Background technology
China is the country of earthquake more than, and violent earthquakes such as Haicheng City, Tangshan have caused massive losses to the people's lives and property.For earthquake disaster, its most basic measure is to do well to provide fortification against earthquakes, and improves the shock resistance of engineering structures.How by reasonable seismic design, strengthening structural seismic capacity is that domestic and international project circle is extremely paid close attention to.One of critical component of seismic design of structures is a shear wall, and it is a kind of main lateral resisting system in the highrise building.Its lateral deformation stiffness is big, the bearing capacity height, but ductility is relatively poor, and brittle fracture takes place easily, and this is very unfavorable to integrally-built anti-seismic performance.
In recent years, steel reinforced concrete combined shear wall construction has obtained using widely in engineering, has been subjected to the consistent favorable comment of engineering circle.The steel reinforced concrete compound shear wall combines reinforced concrete structure and steel work, can remedy shortcoming separately, brings into play their advantage better, makes structure have bigger bearing capacity and rigidity, has better ductility and energy dissipation capacity.Wherein, the steel pipe concrete frame shear wall is a kind of of steel reinforced concrete compound shear wall, has been applied in a lot of highrise buildings." concrete-filled rectangular steel tube structure technology rules " also to the proposition of this shear wall computational methods.This shear wall steel pipe concrete frame strengthens the constraint of concrete panel, and steel core concrete column has better later stage bearing capacity.But the reinforced concrete wall panel in this shear wall is relatively poor as the first line of defence ductility, has influenced whole shear wall so that the lateral resisting ability of total, i.e. shock resistance.
Steel plate shear force wall is to bring earthquake energy by the interior film pulling force of filling out steel plate, and the abundant development that therefore guarantees pull strap is the essential condition of performance steel plate shear force wall superiority.And the important prerequisite that fully develops pull strap guarantees not unstability of frame just.
The utility model content
Technical problem to be solved in the utility model is the problem that significantly improves steel pipe concrete frame ductility of sheer wall, energy dissipation ability, has designed a kind of steel tube concrete-steel support-steel plate external wrapping concrete shear force wall.
The technical scheme that the utility model adopted is: be made of frame and steel plate concrete shear wall slab, steel plate both sides at the steel plate concrete shear wall slab dispose the steel mesh reinforcement of being made up of transverse reinforcement and longitudinal reinforcement, between steel mesh reinforcement, socket with socketing reinforcing bar, it is characterized in that: described frame comprises frame beam and steel pipe concrete frame post, the steel pipe concrete frame post is arranged on the shear wall two ends, in the frame beam section steel beam is set, section steel beam is connected with the steel pipe concrete frame post in the configuration steel support on the embedded steel plate of shear wall, steel support two ends and frame beam; Wallboard is wrapped with concrete; Section steel beam, steel pipe concrete frame post and steel support are formed shear wall and are hidden eccentric supporting steel truss, and at the inner eccentric supporting steel truss that forms strong post, strong support, weak energy dissipation beam section of steel plate concrete shear wall.
Described steel tube concrete-steel support-steel plate external wrapping concrete shear force wall, it is characterized in that: the steel support that is provided with on the shear wall steel plate is herringbone, steel support upper end is stretched in the frame beam of top, be connected with the section steel beam in the frame beam, steel support lower end is stretched in the node of bottom frame beam and steel pipe concrete frame post, be connected simultaneously with the section steel beam in steel pipe concrete frame post and the bottom frame beam, and at inner strong post, strong support, the weak energy dissipation beam section steel truss of forming of steel plate concrete shear wall.
Described steel tube concrete-steel support-steel plate external wrapping concrete shear force wall, it is characterized in that: the steel support that is provided with on the shear wall steel plate is X-shaped, the upper end of steel support is stretched in the node of top frame beam and steel pipe concrete frame post, be connected simultaneously with the section steel beam in steel pipe concrete frame post, the top frame beam, the lower end of steel support is stretched in the node of bottom frame beam and steel pipe concrete frame post, be connected simultaneously with the section steel beam in steel pipe concrete frame post, the bottom frame beam, and at inner strong post, strong support, the weak energy dissipation beam section steel truss of forming of shear wall.
Described steel tube concrete-steel support-steel plate external wrapping concrete shear force wall, it is characterized in that: the steel support that is provided with on the shear wall steel plate is splayed, top frame beam is stretched in the steel support, and be connected with section steel beam in the frame beam of top, steel support lower end is stretched in the node of bottom frame beam and steel pipe concrete frame post, be connected simultaneously with the section steel beam in steel pipe concrete frame post and the bottom frame beam, and at inner strong post, strong support, the weak energy dissipation beam section steel truss of forming of shear wall.
The utility model is that the advantage with steel pipe concrete frame shear wall and steel plate shear force wall makes up, and the steel support is set on steel plate simultaneously, last wallboard external wrapping concrete.Shock resistance of its combination back structure is significantly higher than the addition that steel pipe concrete frame shear wall and steel plate shear force wall work alone.Steel support and concrete existence have solved destabilization problems outside the plane of steel plate, help improving the steel plate shear force wall wallboard partly as shear-carrying capacity, ductility and the energy dissipation capacity of antidetonation the first line of defence.After wallboard destroyed in antidetonation, the steel support was a geometrically stable system with the trussed construction that upper and lower frame beam, steel pipe concrete frame post form, thereby keeps the resistance to overturning of structure.Compare with common steel tube concrete frame shear wall, supporting capacity improves, and bearing capacity and stiffness degradation are slack-off, and the later stage anti-seismic performance is relatively stable, and the bottom shear sliding rupture alleviates.
Because shear wall is the core lateral resisting parts of building structure, has improved the shock resistance of shear wall, has also just improved the whole shock resistance of structure, when building meets with violent earthquake, can alleviate its earthquake, prevent that it from collapsing.
