Description
Technical field
It is more particularly to a kind of to be applied to Coupled Shear Wall knot the present invention relates to architectural engineering and structural seismic technical field
Replaceable double ranks surrender power consumption steel coupling beam of structure.
Background technology
Possess numerous high levels, super high rise structure in modern city.High-rise, super high rise structure is for solution in modern city
Certainly land used is nervous, plays Modern Urban Functions, embodies one of main architectural style that modern city style and features is used.Skyscraper
The horizontal earthquake action and wind load born are larger, and lateral rigidity turns into the principal element controlled during structure design, and reinforcing bar is mixed
Solidifying soil shear wall is good due to overall performance, and anti-lateral rigidity is big, high capacity, the features such as sidesway is small under horizontal loads,
It is widely used in skyscraper.Coupling beam is the consumption of shear wall structure or the contact two panels wall limb of frame shear wall structure
Can component.Traditional coupling beam typically uses reinforced concrete coupling beamses, but due to building demand, it is past that reinforced concrete coupling beamses are designed
It is smaller toward span-depth radio, easily cause the failure by shear of reinforced concrete coupling beamses, influence the ductility and energy dissipation capacity of coupling beam, too early
Destruction prevent coupling beam from by the effect for looking for advance design object to play antidetonation the first line of defence.
In recent years, the country such as the U.S., Canada and New Zealand replaces reinforced concrete coupling beamses using steel coupling beam, by steel coupling beam
Mixing Coupled Shear Wall is combined into armored concrete wall limb.Research finds that steel Design of Connecting Beam is the hysteresis loop of shear yielding
Very full, ductility and energy dissipation capacity are significantly better than the concrete connecting-beam of traditional reinforcing bar.General steel Design of Connecting Beam is rare chance
Power consumption effect is played under earthquake, but due to the demand of architectural design, it is desirable to arch surrender power consumption effect will be proposed under frequently occurred earthquake.
The characteristics of many scholars have developed many replaceable power consumption coupling beams, these coupling beams at present is to connect concrete mostly
One section of energy dissipating beam section is replaced with the middle part of beam.Such way is disadvantageous in that be merely able to meet coupling beam bends under frequently occurred earthquake
Clothes play the effect of additional damping ratio, and the coupling effect of coupling beam connection two panels wall limb can not be played after power consumption surrender, and rare
Power consumption effect can not further be played by meeting under earthquake.
Closest to prior art, Publication No. 104805958A Chinese invention patent applications,《Applied to Coupled Shear Wall knot
Double ranks surrender power consumption steel coupling beam of structure》, a kind of replaceable double ranks applied to Coupled Shear Wall structure of patent document proposition
Surrender power consumption steel coupling beam, with that can play the function of power consumption offer additional damping ratio under frequently occurred earthquake, can also play conduct
The coupling effect of coupling beam, and bigger power consumption effect can be played under rarely occurred earthquake.In addition, connection limb should be applied to
Replaceable double ranks surrender power consumption steel coupling beam of shear wall structure, can equally be changed, lifting building when being repaired after shake
Rapid repair ability after macroseism.

Embodiment
Embodiments of the present invention are illustrated by particular specific embodiment below, those skilled in the art can be by this explanation
Content disclosed by book understands other advantages and effect of the present invention easily.
Fig. 1 is referred to Fig. 7.It should be clear that structure, ratio, size depicted in this specification institute accompanying drawings etc., is only used to
Coordinate the content disclosed in specification, so that those skilled in the art is understood with reading, being not limited to the present invention can be real
The qualifications applied, therefore do not have technical essential meaning, the tune of the modification of any structure, the change of proportionate relationship or size
It is whole, in the case where not influenceing effect of the invention that can be generated and the purpose that can reach, all should still it fall in disclosed skill
Art content is obtained in the range of covering.Meanwhile, in this specification it is cited as " on ", " under ", "left", "right", " centre " and
The term of " one " etc., is merely convenient to understanding for narration, and is not used to limit enforceable scope of the invention, its relativeness
It is altered or modified, under without essence change technology contents, when being also considered as enforceable category of the invention.
As shown in Fig. 1 (a), Fig. 1 (b), Fig. 1 (c) to Fig. 7, specific procedure of processing of installing is：
Then plate-girder two ends are welded in beam-ends by processing and fabricating bending surrender core plate-girder (2) using butt weld first
On end plate.
The floor (4) that will put more energy into is welded on double webs (12).
Then double webs (12) are welded on end plate (3), using butt welding or angle welding.
Then the edge of a wing (11) of dog bone type processing up and down and double webs (12) are welded using angle welding, and and end plate
(3) weld.
Final end plate perforate is docked using high-strength bolt (5) with straight cutting beam section (6).
So far replaceable double ranks surrender power consumption steel coupling beam applied to Coupled Shear Wall structure is machined.
Under frequently occurred earthquake effect, double webs (12) of overcoat I-beam (1) are held due to being made using Low Yield Point Steel
The most shearing actions of load, therefore it is under coupling beam shearing action, will occur the first rank shear yielding, but now bend and bend
The core plate-girder (2) of clothes still keeps elastic stage to provide coupling effect.
Under rarely occurred earthquake, bend surrender core plate-girder two ends elastic region (22) due to overcoat I-beam (1)
The edge of a wing is welded, therefore rigidity very die elastic deformation is smaller, and diamond hole or parabola are opened in plastic bending surrender power consumption area (21)
Behind shape hole, the bent stick of formation will occur second-order bending and surrender under the shearing action suffered by coupling beam.Plus the shearing of the first rank
Double web shear yieldings of surrender, energy dissipation capacity now substantially becomes big, makes structure avoid big shake is lower from occurring serious collapse brokenly
It is bad.
After macroseism, if coupling beam occurs destruction and can so unloaded the high-strength bolt at coupling beam end plate, install newly
Steel coupling beam, makes the function of structure recover as early as possible, reduces the economic loss that earthquake is caused, and recovers the use function of building structure.
