Or the excitation of earthquake load, the vibration of structure are likely to be more than safety standard.In Structural Analysis of High-Rise Buildings, it should study in detail
The effect of wind or earthquake load improves the damping capacity of structure.
Damper is a kind of device for slowing down mechanical oscillation using damping characteristic and consuming kinetic energy, has been widely used in
In building structure.Typically, damper is divided into active, half active and passive control device three categories.In passive control device point
In the damper of class, Tuned Liquid (Tuned Liquid Damper, TLD) generally rectangular cross-section or circular water that is filled with water
Case, length and the depth of water by regulating tank along direction of excitation adjust frequency, by liquid in water tank to tank wall when vibration
Energy dissipating is realized in the shaking of impact force and liquid.Tuning column damper (Tuned Liquid Column Damper, TLCD) is
A kind of special shape of TLD, usually U-shaped rectangular tank fill with liquid in water tank, make TLCD by adjusting liquid length
Frequency close to the frequency of building structure, damage by liquid head caused by the viscous effect in liquid motion and boundary layer by when vibration
It loses and realizes energy dissipating.But general TLCD can only control structure single direction vibratory response, and to high building structure shadow
The input direction for ringing most important wind shake load and earthquake load has uncertainty, therefore it is multidirectional to cannot achieve structure level
Oscillation damping and energy dissipating, for not specified oscillatory load, effectiveness in vibration suppression is unsatisfactory.
Summary of the invention
For overcome it is existing tuning column damper (TLCD) can only control structure single direction vibratory response limitation
Property, column damper is tuned the purpose of the present invention is to provide a kind of circular ring shape, in conventional tune column damper (TLCD)
On the basis of, by the setting of cylindrical body inside and outside shell and L-type partitions, realize the effect to the multidirectional oscillation damping and energy dissipating of structure level.
The technical solution adopted by the present invention to solve the technical problems is:
A kind of circular ring shape proposed by the present invention tunes column damper, which is characterized in that including the cylindrical body being arranged concentrically

The features of the present invention and the utility model has the advantages that
1, the present invention utilizes symmetry of the circular ring shape in horizontal all directions, passes through cylindrical body inner casing, cylindrical shell and L
The setting of type partition, so that controlled structure is when the extraneous vibration by certain level direction motivates, damper in this direction
Liquid motion generates damping effect, realizes building structure in the tuning vibration damping of the direction.The hole of L-type partitions bottom level section can
So that liquid is substantially more vibrated back and forth along excitation orientation, is flowed in damper, to realize better vibration damping effect of energy dissipation；
On the other hand, the damping ratio for accounting for the adjustable liquid of ratio of the bottom level section gross area by changing the perforated area of hole,
To adapt to various forms of structural vibration reductions.The input direction of usual wind shake load and earthquake load has uncertainty, and damps
The symmetry of device fluid column then preferably ensure that structure has preferable multidirectional effectiveness in vibration suppression.
2, structural top mounting circular ring shape tuning column damper be mitigate dynamic exciting dither effect one kind it is feasible,
Easy, effective method.
3, building structure is due to the growth of the age of concrete, and elasticity modulus can change, and then the self-vibration frequency of structure
Rate also changes a lot.When the natural frequency of vibration of the natural frequency of vibration of damper close to structure, there is preferable effectiveness in vibration suppression.This
The natural frequency of vibration for the circular ring shape tuning column damper that invention proposes is i.e. changeable by adjusting liquid-column height, convenient and easy.
