Description
Technical field
The utility model relates to the wind resistance of high level, Super High and tall and slender structure, anti-seismic technology field, is specifically related to a kind of for subtracting
Little high level, Super High and tall and slender structure shake or the passive type mutative damp tuned mass damper device of response under geological process at wind.
Background technology
The construction of the civil infrastructures such as high level, Super High, tall and slender structure is in the ascendant in China, and will be long-term in social economy
Development plays a significant role.China takes precautions against natural calamities as a multiple country of disaster, high level, the antidetonation of high-rise building, wind resistance etc.
Mitigation design is the major issue affecting building safety performance all the time.Since entering the new century, high level, Super High, tall and slender structure
The landmark entering fast-developing period, particularly city has become as the symbol of urban economy strength, how to ensure this
Security under the geological process of high levels, Super High, tall and slender structure and the comfortableness under high wind effect have become with security a bit
For needing the urgent key issue solved.
It is that representational Structure uniformity technology is to be gradually applied to Practical Project, quilt with tuned mass damper (TMD)
Proof can effectively reduce high level, Super High, High-rise Structures Under Wind and seismic response.TMD system is typically by mass, rigidity
Element and damping element are constituted.The quality of the mass of TMD system is generally the 0.25%～1% of structure first mode quality,
The refrigeration system in steel, lead, concrete, building structure or structural elements can be used to make, and the mass of TMD system can
To use multistage pendulum, inverted pendulum, hydraulic support system, laminated rubber bearing etc. to hang or to support；The damping element of TMD system can
To use oil damper, viscoelastic damper and viscous damper.TMD system is the highest at U.S. 244m early than 1977
Hancock is applied on mansion, and TMD system is arranged on the 58th layer of this structure, and mass is made by lead, a size of
5.2 × 5.2 × 1m, quality is 300t, and when the back plate vibration of TMD system reaches 3mg, system starts performance damping effect,
Fieldtesting results shows, the effectiveness in vibration suppression of this system can reach 50%.Subsequently, high at USA New York 287m in 1978
Citicorp mansion on there are also installed TMD system, the size of this TMD System Nature gauge block is 9.14 × 9.14 × 3.05m,
Quality is 410t, is made up of concrete, and when acceleration reaches 3mg, this system starts performance damping effect, on-the-spot
Test result shows, this system controls effect and reaches 40%.
At present, main employing suspension type or brace type TMD in Practical Project.When using suspended TMD, the most outstanding
Put longer, and need to arrange damper, need bigger space to realize, and need annex quality block (generally lead),
And be gravity sensitive structure for high-rise, Super High and tall and slender structure, can be unfavorable to structure stress after annex quality block；Work as employing
During brace type TMD, the usual cost of hydraulic support system is higher, and hydraulic support system is more complicated, implements ratio in engineering
More difficult, and owing to there is no anti-overturning devices, there is the possibility toppled；When using laminated rubber bearing as support system, by
Being flexural deformation structure in high-rise, Super High and tall and slender structure, flexural deformation causes building structure top droop, and TMD sets
Putting the top in structure, TMD mass is relatively big, and water tank has gravity to cause force component in shock isolating pedestal top surface, so that every
Shake bearing occurs shock isolating pedestal to topple under pressure and detrusion, and therefore, rubber earthquake isolation support only should as the support of TMD
Structure for shorter detrusion.

Multidirectional can slide in horizontal plane, be greatly improved the vertical stability of fire water box tuning quality block 1, advantageously reduce simultaneously
Cost.
Further, being additionally provided with pre-embedded steel slab 8 between described sliding bearing 5 and upper concrete short column 6, described slide plate props up
It is additionally provided with lower pre-embedded steel slab 9 between seat 5 and lower concrete short column 7.
Wherein, described bidirectional sliding rail support system 3 includes interconnective bidirectional sliding rail bearing 10 and ball-type twisted branch seat 11, institute
The top of the bottom and building structure 16 of stating bidirectional sliding rail bearing 10 is connected, the top of described ball-type twisted branch seat 11 and fire water
The bottom of case tuning quality block 1 connects.Described bidirectional sliding rail bearing 10 arranges the orthogonal guide rail of double-layer double-direction, is carried out by guide rail
Guide, the built-in ball of slide block, it is achieved the rolling friction of guide rail, reduce frictional force, it is achieved preferably damping effect；Bidirectional sliding rail
The weak axle of 10 1 glide direction correspondence building structure 16 of bearing, the strong axle cloth of another glide direction correspondence building structure 16
Put, it is achieved the control to 16 two direction of vibration of building structure；Between slide rail bearing internal double layers guide rail, spring original paper is set,
As restoring force device, by regulating the rigidity of spring, thus realize by fire water box, the tuning of structure being controlled；Meanwhile,
Safety (crashproof) device can also be set on bidirectional sliding rail bearing 10.
The bottom of described bidirectional sliding rail bearing 10 is connected on the floor of building structure 16, and top is connected to by ball strand type bearing
The bottom of fire water box mass, this ball-type twisted branch seat 11 only can rotate in vertical direction, it is impossible at horizontal rotation in surface,
Ball-type twisted branch seat 11 is 3 ° (general 3 ° can meet demand) at the vertical maximum angle swung, permissible by the angle swung
Uniform load is made to be distributed on each bidirectional sliding rail bearing 10 bearing.
Further, it is additionally provided with top pre-embedded steel slab 12 between described ball-type twisted branch seat 11 and fire water box tuning quality block 1.
Wherein, described mechanical type multistage mutative damp damper system 4 includes mechanical type multistage mutative damp damper 13, described machine
