Integrated form tuning quality damping wall
Technical field
The present invention is a kind of tuning vibration absorber for building structure, the power causing for geological process or wind loadEffect control, belongs to the technical field of building structure passive energy dissipation control, is specifically related to a kind of integrated form tuning quality damping wall.
Background technology
Along with the raising that civil engineering structure antivibration (shake) is required, adopt the engineering structure of structural vibration control technology moreCome more. Comparatively conventional is Passive Control technology wherein at present, has mainly comprised energy-eliminating shock-absorbing technology and tuning vibration damping skillThe large class of art two.
Tuned mass damper (TunedMassDamper, TMD) is a kind of very effective tuning vibration absorber, energyThe response of enough effective attenuation structures under the dynamic load function such as geological process, wind load, is widely used. It is to be attached toA minor structure in main structure, is made up of the inertia producing by TMD system's relative motion mass, spring, damping unitThe reaction of power to main structure, the vibration of control structure. More published tuned mass dampers, conventionally need to be in structureConcentrate additional huge mass, not only occupied certain building usage space, and cause very large holding to place floorLoad with load; Meanwhile, because floor position and matter quantitative limitation, its vibration damping controlled frequency narrow range, for widebands such as geological processesThe effectiveness in vibration suppression of drive load is less; The various devices of partially-tuned Tuned mass damper are exposed in working environment, and performance is subject toAmbient influnence.
In recent years, owing to can making full use of the advantages such as space, energy dissipation capacity that body of wall provides be strong, damping wall more and moreHow in building construction vibration control design, occur, but current published most of damping wall is (as viscous damping wall(application number 201410262093.5), viscoelastic damping wall (application number 201310124804.8), plumbous damping wall (application number201110130891.6), magnetorheological intelligent damping wall (patent No. ZL200420037740.4) etc.) be based on energy-eliminating shock-absorbing formerThe device of reason, utilizes the rare report of damping wall of tuning vibration attenuation mechanism. Meanwhile, the device of this class based on energy-eliminating shock-absorbing principle oftenRequire agent structure that (such as the malformation under large shake effect) after certain distortion occurs, good damping energy dissipation just can be providedAbility, has limited the application of damping wall to a certain extent.
Therefore, take into full account the advantage of tuned mass damper and damping wall, develop a kind of space and economize, arrange spiritLive, control the integrated form tuning quality damping wall that bandwidth, damping energy dissipation are stable, reliability is high and there is certain meaning.
Summary of the invention
The object of the invention is to overcome the problem that prior art exists, a kind of integrated form tuning quality damping wall be provided,This damping wall space province, flexible arrangement, control bandwidth, energy dissipation capacity is strong, reliability is high, can realize prefabrication and assembly constructionIntegrated form tuning quality damping wall, this device has certain additional stiffness and energy dissipation capacity simultaneously, has increased the rigidity of structureAnd damping, can have the effect of steel support and damping wall concurrently.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
Integrated form tuning quality damping wall, comprises support, damping cylinder barrel, and quality of regulation piece, spring, guide rod, damping mass piece, leadsTo cover and attaching nut, in described support, be placed with damping cylinder barrel described in several, in described damping cylinder barrel, be provided with described adjustingMass, described spring, described guide rod, described damping mass piece, described fairlead and described attaching nut, described quality of regulationPiece is all connected with described guide rod with described damping mass piece, and the two ends cover of described guide rod has described spring, and described spring is in instituteState between quality of regulation piece and described attaching nut, described attaching nut is connected with described fairlead.
Further, in the described damping cylinder barrel between described fairlead, be full of viscous fluid.
Further, described support is made up of vertical rod, longitudinal cross bar, horizontal cross bar and diagonal brace, is supporting tuning damping listWhen unit, form the support system of lattice, for agent structure provides lateral rigidity, born part lateral load.
Preferably, described damping cylinder barrel is by master cylinder, and attached cylinder and sealing nut form, and described damping mass piece is provided with dampingHole.
Further, described quality of regulation piece and described damping mass piece provide quality jointly, and described spring provides rigidity,Inertia force causes the slip of described damping mass piece, makes the viscous fluid damping hole of flowing through produce needed damping, these matterIt is tuning oscillator that the element of amount, rigidity and damping has formed a tuning damping unit jointly.
Preferably, on described quality of regulation piece, described attached cylinder and described sealing nut, offer hole, to discharge described adjustingAir pressure in the described attached cylinder that mass evolution causes.
Further, the parameter of described several tuning damping units in same Pin body of wall can be different, described tuningDifferent damping parameter within the walls can be different in same building structure for damping unit, realize wide band control range.
Beneficial effect of the present invention:
The present invention can flexible arrangement in space, without custom-designed space, also will not concentrate on by tuning qualityThe a certain position of structure, less on the impact of building structure conventional design. There are multiple tuning damping units, a Pin damping within the walls orTuned frequency between many Pin damping wall can be different, and therefore tuned frequency can have wider frequency band by rational design and dividesCloth. Therefore, this tuning damping wall not only can suppress the narrowband responses such as wind vibration response preferably, and effective Earthquake occurrence controlThe broadband dynamic loads such as effect. Owing to adopting tuning vibration attenuation mechanism, even under less malformation, damping wall also can be carriedFor stable damping energy dissipation ability. Under dynamic load function, this damping wall has not only been shared the part side direction lotus of agent structureCarry, and consumed partial vibration energy by the principle of tuning vibration damping, effectively reduced agent structure vibratory response, protectionStructural safety. This device can be widely used in the vibration control of building structure.
