Technical field:
The utility model relates to a kind of building structural element, and particularly a kind of no flexing energy dissipating is supported.
Background technology:
As everyone knows, modern building structure all will be considered the antidetonation of structure, especially is built in the building of earthquake zone, and structure Design also needs to consider wind resistance in addition, and steel work is widely used in many civil engineerings owing to good material property.Along with expanding economy and quickening of urbanization process, the quantity of high-rise building is constantly increasing, and wherein with steel work and steel and concrete combined structure proportion maximum.The existing building structural system adopts bending resistance steel frame system, support frame structure and dual structure architecture mostly, and wherein commonly used with the moment resisting system.But for the highrise building of moment resisting system, become gentle relatively owing to the height of building makes its structure, the distortion of structure often surpasses the sidesway limit value of regulation and stipulation, so structure just needs to improve whole rigidity.In addition, under the effect of violent earthquake, structure can produce excessive nonlinear deformation, often causes shake back structure repair difficulty or rehabilitation cost too high, thereby does not meet economic requirement.Support frame structure has better economic, but because traditional support steel structure system can produce flexing when supporting pressurized, so often need to strengthen the section of support to meet design requirement, from and reduced its economy, nonetheless, still can not guarantee under strong motion, to avoid the generation of flexing.In view of this, the member that more external software engineering researchers invent do not have flexing to take place when going out a kind of pressurized, be called buckling-restrained support (Buckling-Restrained Braces) or do not have flexing energy dissipating support, they are used in high building structure as damper.At present, no flexing energy dissipating is supported and has been obtained extensive use in countries such as Japan, the U.S., Canada.
Common be supported on to bear when axial compression reaches certain limit the flexing phenomenon will take place, after flexing takes place, support and just lost supporting capacity, no flexing energy dissipating is supported flexing can not taken place when bearing axial compression, but surrender the same with tension, thereby can absorb the energy of the whole system of input in a large number, therefore can be used as a damping unit.
No flexing energy dissipating is supported and generally is made up of following three essential parts: axle power member unit, buckling-restrained unit and linkage unit.Axle power member unit is positioned at the axle center, buckling-restrained cell rings wrap in it around, linkage unit is at two ends of axle power member unit.
When axle power member unit pressurized,, make a power member unit flexing can not take place owing to be subjected to the constraint of outside buckling-restrained unit.When pressure reaches certain limit, thereby axle power member unit can be surrendered the energy of dissipation input system.It generally is to be connected on the bean column node of steel structure frame with the form that the axle center is supported that no flexing energy dissipating is supported, and it mainly is used as horizontal force resistant (wind or the earthquake) member of structure.Under horizontal loads, flexing does not take place as long as support, the energy that it just can absorb input system has played the effect of the damper of structure.
1988, disclosed a kind of common no flexing energy dissipating in the paper that publishes on the constructionism collected works 34B of the Architectural Institute of Japan volume " by the research of the no bonding support of buckling-restrained concrete and steel tube confinement parcel " (A study on the unbondedbrance encased in buckling-restraining concrete and steel tube) and supported, Fig. 1 and Fig. 2 are seen in its structure and installation.The axle power member unit 11 that no flexing energy dissipating support 10 shown in the figure is made of steel plate, the buckling-restrained unit 12 that square steel pipe constitutes, the filler cells 13 that concrete constitutes, unsticking order unit 14 and the linkage unit 15 that chemical material constitutes are formed, the one end is connected on the node of the post 20 of steel work and beam 30, and its other end is connected on another node of this steel frame.Steel plate 11 bears a power load; Flexing takes place from steel plate 11 being formed constraint on every side to prevent steel plate 11 in square steel pipe 12 and concrete 13 when being carried to certain limit; Unsticking order unit 14 can cut off steel plate 11 and concrete 13, so that can free telescopic slide during steel plate 11 pressurizeds and deform when surrender; Steel plate 11 extends the outside of square steel pipe 12, and vertically is welded with upright strengthening steel slab 16 in its end, to prevent not having external constraint and issuable flexing.Thereby the extension end of steel plate 11 and strengthening steel slab 16 have just formed the section (seeing Fig. 2 A-A section) of "+" font have constituted linkage unit 15 like this, and the two orthogonal junction plates that are made of steel plate that stretch out on this linkage unit 15 and the steel structure node are by being connected batten plate and bolt couples together.
Above-mentioned existing no flexing energy dissipating is supported 10 and is had many shortcomings, wherein has two shortcomings to be:
1, huge, the structure of the size of whole support is fixed, and can not be used for the position that multiple occasion, especially load are little, the space is little flexibly, near bean column node.
2, the manufacturing of whole energy dissipating support is relatively more difficult.It need wrap up the steel plate at center chemical unsticking and meet the central authorities that put into the square steel pipe tube chamber vacantly behind the material, injects the concrete packing material then around steel plate, and when cast, will guarantee that also the steel plate at center can not have skew; In addition, if steel plate cross section, center is very little, just bigger initial deformation may take place at the manufacturing process light plate, thereby influence the performance of its performance.
Summary of the invention:
At the deficiency of prior art bad adaptability, manufacturing difficulty, the utility model provides the variable steel plate type of a kind of physical dimension can regulate no flexing energy dissipating and has supported, and it has wide accommodation, manufacturing process is simple and be suitable for the advantage that factory normalization is produced.
