Abstract
A lead pin viscoelastic damper for an engineering structure is a device which is used for resisting earthquakes and damping earthquakes in civil engineering. The damper is composed of an intermediate steel plate, two side steel plates, damping layers and lead pins, wherein the damping layers are respectively bonded on both sides of the intermediate steel plate, and the two side steel plates are respectively bonded on outer sides of the damping layers; the intermediate steel plate, the two side steel plates and the damping layers are respectively provided with lead pin holes, and the lead pins penetrate through the lead pin holes so that the intermediate steel plate, the two side steel plates and the damping layers are connected with each other into a whole; the damping layers can be in a multilayer structure which is formed from steel plates arranged alternately and damping material layers.
Description
One, technical field
The present invention is a kind of antidetonation and damping device that is applied to civil engineering, the device that especially a kind ofly is applicable to indoor and outdoor, when being applicable to big small earthquake engineering structures is protected.
Two, background technology
Viscoplasticity vibration damping energy dissipating damper is as a kind of effective means of building structure energy-eliminating shock-absorbing, alleviates the earthquake of engineering structuress such as multi-rise building, bridge, tower mast and the reaction under the wind-force effect on can be largely, guarantees its safety under shaking by force.The visco-elastic damping material that viscoelastic damper uses is a kind of high molecular polymer.Visco-elastic damping material is used in military affairs, space flight, aviation, automobile and the mechanical engineering the earliest, but they all belong to the high frequency damping technology.The vibration that building or bridge produce under wind, geological process is the multiple degrees of freedom low frequency vibration, and its damping technology is a new research field.At present, countries such as the U.S., Japan and New Zealand maintain the leading position in this Research on New with in using.What abroad develop and use in engineering all is viscoelastic dampers of no lead dot, and it is less that such viscoelastic damper exists initial stiffness, the distortion under the long duration load---the bigger shortcoming of creeping.
For example apply for by Minnesota Mining and Manufacturing Company, (the Chinese invention patent application number: 96195645.3) this damper is by steel plate with damping layer is bonding forms by " structure of modular damper and this damper " of JT Wei Gelusi invention, after this damper is stressed, stressed by damping layer from start to finish, be disposable stressed, so damping action and effect are unsatisfactory.Especially aspect shock-resistant and energy-dissipating, bigger little shake can not provide bigger anti-side rigidity to engineering structures to the damper of this kind structure to probability of occurrence.The damping layer of this damper is generally made with visco-elastic damping material in addition, and is the same with rubber, and its performance is very sensitive to temperature, temperature is low can be crisp firmly, the temperature height then feel like jelly, the damping of the two is all bad, optimum temperature roughly is about 17 ℃.The modular damper of new Wei Gelusiji generally can only be used for little air-conditioned indoor of variations in temperature, should not be used for outdoor.
Three, summary of the invention
1, technical problem
Purpose of the present invention just provides and a kind ofly can be applicable to indoor and outdoor, has the two-stage mechanical characteristic, engineering structures is all had the viscoelastic damper of lead pin for engineering structure of good anti seismic efficiency in large and small earthquake.
2, technical scheme
The present invention is a kind of viscoelastic damper of lead pin for engineering structure, formed by damping layer and steel plate, this damper is the damper of secondary loading type, by middle steel plate, the both sides steel plate, the damping layer that second stage is stressed, phase I, stressed lead dot was formed, both sides at middle steel plate are bonded with damping layer respectively, the outside at damping layer is bonded with the both sides steel plate respectively, at middle steel plate, be respectively equipped with the lead dot hole on both sides steel plate and the damping layer, lead dot is through in the lead dot hole, with middle steel plate, the both sides steel plate, damping layer holds together, wherein the suffered shearing of lead dot divides two stages, be the phase I when shearing is not too big, mainly stressed by lead dot, when shearing increases to the lead dot interval, then entered for the second stressed stage, at this moment the shearing born of lead dot no longer increases, and is normal value, and remaining shearing is all born by damping layer, bear the stressed damping layer of second stage, can form sandwich construction by steel plate and damping material layer that polylith is arranged alternately.
3, beneficial effect
The invention has the advantages that this damper can be used for alleviating the dynamic responses of engineering structures under wind and geological process such as multi-rise building, tall and slender structure, bridge construction, large-span structure, the Aseismic Reliability that improves engineering structures also reduces construction costs, its concrete advantage have following some:
1) " viscoelastic damper of lead pin for engineering structure " invented has enough rigidity, distortion and the stability of control structure under wind action effectively, can reduce effectively structure action of long-term load under creep deformation;
2) " viscoelastic damper of lead pin for engineering structure " invented can absorb vibrational energy effectively by the visco-elastic damping layer between steel in the middle of being arranged on and both sides steel plate;
3) " viscoelastic damper of lead pin for engineering structure " invented can be by passing across the lead dot of both sides steel plate, middle steel plate and visco-elastic damping layer, has stressed characteristic of two-stage, in big small earthquake, engineering structures all there is good anti seismic efficiency, improve its rigidity and energy dissipation capacity effectively, can be applicable to the engineering structures of indoor and outdoor;
4) " viscoelastic damper of lead pin for engineering structure " invented can be used for the inhibition of the structural vibration that horizontal vibration and vertical motion cause;
5) " viscoelastic damper of lead pin for engineering structure " invented can be used for the vibration damping of building structure, bridge construction and large-span structure or the like various engineering structure;
" viscoelastic damper of lead pin for engineering structure " simple structure of 6) being invented, power transmission is clear and definite, mechanism is clear.
