Description
Technical field
The present invention relates to assembled integral shock-absorbing support, belong to civil engineering structure energy-dissipating and shock-absorbing（Shake）Technical field.
Background technology
Anti-buckling support is a kind of common energy-consuming shock absorber, and relatively broad answering has been obtained in building engineering field
With.Common support flexing unstability under big shake effect, close to by bender system.The outsourcing confining part limitation branch of anti-buckling support
The flexural deformation of support, makes support be primarily subjected to axial force, and can surrender power consumption in tension and compression.This tension and compression same sex causes anti-bending
Bent support system has the advantages that low cost, strcture safety are high and structure design is flexible than common support framework.But it is anti-
Buckling support there is also limitation in itself.In/big shake under anti-buckling support energy consumption function admirable, but small shake and it is micro- shake under, prevent
Buckling support does not consume energy still in elastic stage.Skyscraper and tall and slender structure so high for sidesway, comfort level requirement comes
Say, anti-buckling support system cannot meet requirement.
Viscoelastic damper is cohered with steel plate overlapping by viscoelasticity damping material and formed, and the shearing by viscous-elastic material is stagnant
Energy dissipation behavior is returned, additional stiffness and damping are provided to agent structure, reduce the dynamic response of agent structure, reach the effect of vibration damping
Really.Viscoelastic damper dependable performance, simple structure, energy dissipation capacity are strong, and can consume energy in the full stage, and that is supported unlike anti-buckling
Sample needs larger relative displacement ability yield deformation to play power consumption effect.
There is researcher to propose the different power consumption principles of comprehensive utilization or mechanism to design novel energy-consumption shock-absorbing device, i.e. energy consumer
The thought for being consumed energy using two or more mode simultaneously, has researched and developed various new dissipative vibration-damper.
There is engineering staff to propose the force-mechanism of anti-buckling support combination in parallel with viscoelastic damper in recent years.One kind system
It is that viscous-elastic material one side is pasted with core as method, is simultaneously pasted with shearing steel plate.Shearing steel plate also serves as outsourcing about simultaneously
Beam component.Core is deformed under responsive to axial force, while driving viscous-elastic material to produce detrusion and consume energy, so may be used
With realize it is anti-buckling be supported on deformation it is smaller when consume energy.There is larger defect in this production method.On the one hand, detrusion is uneven
Even, middle small two is big, and the viscous-elastic material detrusion of support middle part can be much smaller than the detrusion of viscous-elastic material at two ends,
Utilizing status so for viscous-elastic material are poor.On the other hand, viscous-elastic material is needed by high temperature with pasting for steel plate
Vulcanization, stove heat not only inconvenience but also influence low cycle fatigue property are integrally entered by the core of support.Additionally, core is under the condition of palsticity
Deformation is larger, along with viscous-elastic material detrusion is uneven, easily causes the tear of viscous-elastic material.
Also a kind of preparation method is that viscous-elastic material two sides sticks in two pieces of shearing steel plates respectively, and inboard shear steel plate is tight
By core, weld together in end with core.Outboard shear steel plate also serves as the outsourcing constraint structure of anti-buckling support simultaneously
Part.Although so avoiding the problem in terms of former preparation method brings above three, also there is weak point.One side
Face, in order to meet viscous-elastic material detrusion the need for, outsourcing confining part internal reservation certain space thus can not
To core surrender section carried out in length range it is buckling-restrained, so as to form obvious weak spot.On the other hand, it is contemplated that security
With economy, when core drawing/compressive strain reaches design load, viscous-elastic material detrusion should deform close to Ultimate Shear；Core
During in elastic stage, viscous-elastic material detrusion is smaller, and the finite energy of dissipation, stock utilization is relatively low.
The content of the invention
It is an object of the invention to overcome drawbacks described above from working mechanism and structural form, a kind of assembled integral is proposed
Shock-absorbing support.Its working mechanism be after the viscoelasticity damping element with limit function is connected with spring member again with it is anti-buckling
Supports in parallel.When assembled integral shock-absorbing support overall deformation is smaller, the power consumption core of anti-buckling support component is in elasticity
Stage does not consume energy, viscoelasticity damping element detrusion power consumption；When assembled integral shock-absorbing support overall deformation is larger, power consumption
Core surrender power consumption, be limited in license deformation range for the detrusion of viscous-elastic material by baffle plate, and spring undertakes major part
Deformation.Viscoelasticity damping element cooperates with anti-buckling support component, is consumed energy by viscoelasticity damping element during small deformation, big to become
Mainly consumed energy by anti-buckling support component during shape.
