Buddhist nun's device.For house architectural structure, science of bridge building energy-dissipating and shock-absorbing.
Background technology
Traditional building construction anti-shock methods are resisted by increasing the section of component and increase arrangement of reinforcement, the result is that cutting
Face is bigger, and rigidity is bigger, and geological process is also bigger, is not only difficult to ensure that safety, also greatly improves the cost of engineering, energy dissipating subtracts
The introducing of shake technology solves this problem.Energy-eliminating shock-absorbing technology is used as the damage of mitigation structural earthquake, raising structural seismic performance
Effective means, its mechanism of action is that the energy-consuming shock absorber alternative structure supporting member that is installed in structure of order goes to absorb and consumed
Dissipate seismic energy, the seismic response of attenuating structure, so as to ensure that the functions such as the security of structure, comfortableness and normal usage
It is required that.
The energy dissipation damper species being presently available in shock-damping structure is various, such as metal yield type damper, friction resistance
Buddhist nun's device, fluid linking damper etc..But most damping units are consumed energy using homogenous material, and such as metal yield type damper mainly passes through gold
The shear-bow deformation dissipation outside input energy of category, damper upper and lower side support may be regarded as Rigid Region, and only damper is cut
Shear deformation.Under small shake or the effect of weak wind shake, structure stratified deformation is smaller, and damper is in the elastic working stage, can give structure
Certain additional stiffness is provided；Bestir oneself in big shake or high wind under use, structure stratified deformation is larger, damper is sent out prior to agent structure
Raw surrender, into elastoplasticity working stage, is dissipated outside defeated using the shearing lag return deformation and flange inflection deformation of web
Enter energy, so as to be effectively reduced the earthquake response of structure.
Though there is also concrete in traditional BRB dampers, concrete only constrains core plate compressive buckling and is not involved in
Power consumption.
The content of the invention
Fiber concrete is as a kind of new material, with stronger deformability, and ductility is good, and energy dissipation effect is good.
The present invention is proposed initiatively, with reference to metal and the energy-dissipating property of two kinds of materials of fiber concrete, designs a kind of fiber coagulation
Earth metal surrender type damper, is applied to this kind of damper of metal shears cutting plate by fiber concrete first, utilizes fiber concrete
And the shear-bow of metallic plate deforms common dissipation outside input energy, the present invention has obvious novelty, and energy consumption effect shows
Writing improves.
It is mixed there is provided a kind of excellent fiber of energy-dissipating property it is an object of the invention to subtract shock insulation (shaking) for civil engineering structure
Solidifying earth metal surrender type damper, is consumed energy using two kinds of materials of steel and fiber concrete, improves energy dissipation capacity.
The present invention needs technical scheme to be protected to be characterized as：
A kind of fiber concrete metal yield type damper, including upper and lower side connecting plate, left and right sides flange plate, front and rear abdomen
Plate, it is characterised in that also including fiber concrete, structure is：

Both sides flange plate passes through solder design with upper and lower end connecting plate；Formed by front and rear web, both sides flange plate and upper and lower side connecting plate
The inner space of one closing.
Ribbed stiffener can be set in inner space, can be also not provided with.
Technical solution of the present invention can also include ribbed stiffener.It is diagonally arranged that the ribbed stiffener can be welded into cross, X-type
Deng conventional a variety of layout patterns.
The cross ribbed stiffener is arranged in formed inner space, is divided into filling out in multiple area's lattice, area's lattice
Fiber concrete is filled, fiber concrete has the features such as ductility is good, energy dissipation effect is good, while two coxostermums are constrained, to abdomen
Plate local buckling and flexing have certain effect of contraction.
The present invention has materials easy, and initial stiffness is big, and Hysteresis Behavior is stable, and out-of-plane buckling is small, and plastic deformation ability is big
The advantages of, the energy-dissipating property of two kinds of materials of fiber concrete and steel can be given full play to, economy is strong.
Described front and rear web can select the steel of a variety of strength grades such as Q100, Q160, Q225, Q345.Utilize steel
Shear-bow deformation dissipation outside input energy.
Described left and right sides flange plate uses common iron, is shaped as rectangle, web and fiber concrete before and after constraint.
Described upper and lower side connecting plate uses common iron, can be bolted or solder design makes damper and branch
Support is connected to become entirety.
Described ribbed stiffener uses common iron, can be welded into it is cross, with upper and lower side connecting plate and both sides flange plate
By solder design, ribbed stiffener can be connected as a single entity with front and rear web by welding.
The modulus of elasticity of described fiber concrete is relatively low, but has stronger deformability, with metalloid material
Stretching reinforcing feature, ductility is good, and energy dissipation effect is good.Two coxostermums are constrained simultaneously, have one to web local buckling and flexing
Fixed effect of contraction.
The arrangement form of fiber concrete metal yield type damper of the present invention in the structure can use support type and intercolumniation
Type.
The advantage of the invention is that the existing conventional metals surrender type resistance of described fiber concrete metal yield type damper
Buddhist nun's device materials are easy, and initial stiffness is big, and Hysteresis Behavior is stable, and out-of-plane buckling is small, and the advantages of plastic deformation ability is big can fill again
The energy-dissipating property of two kinds of materials of fiber concrete and steel is waved in distribution, and economy is strong.Ribbed stiffener is set between web, abdomen is improved
Unstability outside face occurs for the buckling stress of plate, delay web.Fiberfill fibers concrete in the lattice of inner area, both participates in power consumption, while right
Web local buckling and flexing also have certain effect of contraction, so that more sufficient shear energy dissipation.
