Abstract
The present invention relates to the tuned mass damper based on anti-buckling constraint support, mainly includes inner ring mass, outer shroud mass, rubber friction layer, bearing pin, anti-buckling constraint support, cross connecting rod, angle splice bar, high-strength bolt, active beam link, otic placode；Relatively rotated between inner ring mass and outer shroud mass, utilize the friction energy-dissipating between rubber friction layer；Damping energy consumption effect under the stability and macroseism of anti-buckling constraint support enhancing tuned mass damper, mass is swung during earthquake, while providing reverse reverting power for structure, accelerates the anti-buckling power consumption for constraining and supporting.The mass transfer of mass will accelerate this section to enter the plastic stage and consume energy to active beam link, and cause agent structure from aggrieved, and so design is changed after being easy to shake.
Description
Technical field
The invention belongs to construction steel structure seismic resistance field, and in particular to a kind of tuning quality based on anti-buckling constraint support
Damper.
Background technology
Mono-pendulum type tuned mass damper（TMD）It is made up of mass, swing rope and damping system, passes through the self-vibration frequency of adjustment
Rate, the controlled frequency of agent structure is close to, when agent structure forced vibration, produces the fortune opposite with agent structure therewith
Move and apply reaction force and progressively dissipated by damper in agent structure, the vibrational energy of input structure, so as to control structure
Vibration.
The axially loaded component of unstability will not occur when being a kind of compression for anti-buckling constraint support, mainly there is two parts group
Into：Kernel core unit and restraining tube unit, between the two by filling pea gravel concreten, realize the pact to internal core
Beam, separated between concrete and internal core steel member by one layer of thin material, pass through the soft steel core of low-yield during earthquake
Material produces larger plastic deformation under course under cyclic loading, consumed energy, reduces seismic structural response.
Traditional TMD damper uses viscous damper more, and the output of viscous damper is directly related with piston hole, when long
Between using piston hole can be made to widen one's influence damped coefficient, and frequent oil leak in viscous damper use, so viscous damper
It is not to provide damping the best way for TMD；And tradition TMD damping effects are bad during macroseism.
The content of the invention
The problem of existing for the damper for improving traditional TMD, anti-buckling constraint support applications are damped in tuning quality
Device, ensure the stability of damper；Meanwhile the swing of mass improves the energy consumption effect of anti-buckling constraint support；By TMD matter
Amount is directly passed to active beam link, reduces its influence for normal configuration, and and can allows active beam link to enter plastic deformation ahead of time
Power consumption, reduce the seismic response of agent structure.
To achieve these goals, the present invention adopts the following technical scheme that：
Based on it is anti-buckling constraint support tuned mass damper, by inner ring mass 1, outer shroud mass 2, rubber friction layer 3,
Bearing pin 4, anti-buckling 10 groups of constraint support 5, cross connecting rod 6, angle splice bar 7, high-strength bolt 8, active beam link 9 and otic placode
Into；Girder steel and steel column connect two-by-two, form frame structure, and the tuned mass damper is located in frame structure, and its feature exists
In：Inner ring mass 1 is linked to be entirety with outer shroud mass 2 by tongue-and-groove, and the outside of inner ring mass 1 is stained with rubber friction layer 3, interior
Ring quality block 1 is connected by bearing pin 4 with cross connecting rod 6, and the upper end of cross connecting rod 6 is connected by high-strength bolt 8 and angle steel
The one end of fishplate bar 7 is connected, and the other end of angle splice bar 7 is connected by high-strength bolt 8 with active beam link 9；The active beam link 9 is located at
On the top girder steel of frame structure, anti-buckling constraint support 5 has four, is arranged according to X-shaped, wherein two anti-buckling about bundle branches
Support 5 one end by bearing pin 4 and otic placode 10 with outer shroud mass 2 to be connected, the other end is connected by bearing pin 4 with girder steel or steel column；Separately
Two anti-buckling 5 one end of constraint support are connected by bearing pin 4 and otic placode 10 with inner ring mass 1, and the other end passes through bearing pin 4 and steel
Beam or steel column connection.
In the present invention, can be relatively rotated between inner ring mass 1 and outer shroud mass 2, using with rubber friction layer 3
Between friction energy-dissipating.
In the present invention, by cross connecting rod 6, the mass transfer of inner ring mass 1 and outer shroud mass 2 to dissipative links
Section 9, will increase the active beam link internal force, makes top girder steel concentration of plastic deformation at this in active beam link, is changed after being easy to shake.
In the present invention, different cornerwise anti-buckling constraint supports 5 respectively by bearing pin 4 connect inner ring mass 1 with it is outer
Ring quality block 2, and the positional symmetry distribution of bearing pin 4, connection ensure in malformation, the anti-buckling constraint on different diagonal
Support 5 produces opposing torque.
In the present invention, when earthquake occurs, inner ring mass 1 is swung together with outer shroud mass 2, is provided reversely for structure
While restoring force, accelerate the power consumption of anti-buckling constraint support 5.
Compared with prior art, the beneficial effects of the present invention are：
1）Compared with traditional TMD, consumed energy using anti-buckling constraint support as damper, when improving TMD stability and macroseism
Damping energy consumption effect.
2）The swing of mass will amplify two end movements of anti-buckling constraint support, so as to accelerate anti-buckling constraint support（'s
Power consumption, improve damping energy efficiency.
3）The quality of mass is directly passed to active beam link, the beam section internal force can be increased, be plastically deformed beam section
Concentrate here, and agent structure is changed from destroying after being easy to shake.
