On four hoist cable one end were connected to major structure core tube cap truss, the coagulate soil box body was suspended in midair to one end, the inside an amount of steel ball of placing of box, and the box inner wall posts low coefficient of restitution's cover surface course simultaneously. When suffering the violent earthquake suddenly, collision, the granule of accessible granule and container wall directly rubs and the mechanism power consumption such as are out of shape, and the ability that consumes energy reinforce can improve core cylinder structure's anti -collapse capability at to a great extent. The utility model discloses device processing is convenient, and the stable performance to the strong adaptability of environment, has wide application prospect.
Description
Technical field
The utility model is related to lift the device of core wall structure collapse resistant capacity using particle damping.Belong to soil
Wood engineering structure（Including skyscraper, tall and slender structure and bridge structure etc.）Design to resist progressive collapse field.
Background technology
In recent years high-rise building develops more and more rapider in China, and especially the high-rise building of 500 more than m exists
China various places continue to bring out.China is earthquake district occurred frequently, for structure design personnel, needs accurate assurance high-rise building
Anti-seismic performance, propose rational earthquake resistant construction.The shock resistance of engineering structure is the important means of Seismic Resistance And Disaster Reduction, and building exists
Destructiveness in earthquake can be equal to the order of severity of earthquake.Build for entire society and the people's lives and property safety
It is all mostly tube structure that the shock resistance for building thing is all highly important and current super high rise structure, thus cylinder is tied
The collapse resistant capacity of structure is even more and is directly connected to the people's lives and property safety.
Current design to resist progressive collapse is broadly divided into 2 classes：The Aseismic Design that one class is resistant to geological process and carries out；It is another kind of
It is for setting that the opposing structural continuity that more and more Special Loads and the attack of terrorism such as blast, impact is caused collapses and carries out
Meter.The destruction collapsed mainly under horizontal force action of Structures under Earthquake thing, is far above to form one or two in collapsing procedure
Individual mechanism, but while appearance is multiple, even flood post or other lateral resistant members are all destroyed.With the formation of mechanism,
Redistribution in structural internal force, some component unloadings there is, and other component overload, failures, chain reaction is ultimately formed, structure is whole
Body or local are collapsed.Progressive Collapse is failed under the Special Loads effect such as blast, impact by the component of local, is led
There is Internal Force Redistribution and fail in the component around causing, under structure Action of Gravity Field so as to cause progressive failure.Advised with the U.S.
For the definition of model, exactly initial local unit is destroyed to other unit extensions, ultimately result in structural integrity or big model
Enclose collapsing for region.Collapsing for Structures under Earthquake may occur along with Progressive Collapse, otherwise but be false.
For the design to resist progressive collapse under geological process, we can consume geological process using common energy-consuming shock absorber
Energy, it is to avoid structure produces larger displacement and Progressive Collapse occurs.In recent years, particle damping more and more should
Use field of civil engineering, if can just think be applied to tube structure by particle damping, using particle and wall and
The a large amount of earthquake energies of collision between particle, it is also possible to improve the collapse resistant capacity of tube structure.
The content of the invention
The purpose of this utility model is to provide a kind of using particle damping lifting core wall structure collapse resistant capacity
Device.
To achieve these goals, the utility model is adopted the following technical scheme that：
The utility model proposes application particle damping lifted core wall structure collapse resistant capacity device, by four
Hoist cable 1, the concrete casing 2 of an one end open, steel ball 3 and covering surface layer 4 are constituted, wherein：Four one end of hoist cable 1 are connected to
On the cap truss of agent structure Core Walls Structure, other end suspention concrete casing 2, some steel balls 3 are placed in the inside of concrete casing 2,
Simultaneously the inwall of concrete casing 2 posts the covering surface layer 4 of low restorer number；When there is violent earthquake suddenly, concrete box
Body 2 is vacillated now to the left, now to the right, and drives internal steel ball 3 to move, and is collided with the inwall of concrete casing 2, meanwhile, steel ball 3 and steel ball 3
Between frictional impact also can occur.When there is violent earthquake suddenly, concrete casing 2 is vacillated now to the left, now to the right and drives internal steel ball 2 to move
Move and collide with concrete cabinet wall, frictional impact also can occur between steel ball and steel ball.Can be by steel ball and coagulation
The mechanism such as collision, the steel ball friction texturizing of native cabinet wall consume energy, and energy dissipation capacity is strong, can to a great extent improve Core Walls Structure knot
The collapse resistant capacity of structure.
In the utility model, the steel ball of the filling accounts for concrete tank capacity less than 2/3.
In the utility model, it is a kind of material of low restorer number to cover surface layer, and more energy are can absorb during collision.
The utility model device is easy to process, stable performance, the strong adaptability to environment.
Compared with prior art, the beneficial effects of the utility model are exactly：
1. when there is violent earthquake suddenly, concrete casing vacillates now to the left, now to the right the internal steel ball movement of drive simultaneously to the utility model
Collide with concrete cabinet wall, frictional impact also can occur between steel ball and steel ball.Can be by steel ball and concrete box
The mechanism such as collision, steel ball friction texturizing of wall power consumption in vivo, energy dissipation capacity is strong, can to a great extent improve core wall structure
Collapse resistant capacity.
2. the utility model device is easy to process, stable performance, the strong adaptability to environment.
