Description
Technical field
The invention belongs to building aseismicity technical fields, more particularly to a kind of segmented steel plate viscous damping wall.
Background technique
Earthquake disaster have it is sudden and crushing, seriously threaten the safety of human life, property.Annual hair in the world
Raw ruinous earthquake nearly thousand times, a violent earthquake can cause the economic loss of more than one hundred billion dollar, cause hundreds of thousands people dead or tight
It is severely injured residual.China is located on two most active earthquake zones in the world, is the one of the countries with the most serious ... that suffers disaster from an earthquake, earthquake
Caused by casualties occupy first place in the world, economic loss is also very huge.In earthquake the considerable damage of building with collapse, be to make
At the immediate cause of earthquake disaster.When earthquake occurs, ground vibration causes the earthquake response of structure, is fixed in ground for basis
Building structure, reaction along highly from top to bottom successively amplification.Since the earthquake response of works a part is as accelerated
Degree, speed or displacement are excessive, although main body load-carrying members is made seriously to destroy or even collapse or main structure is not destroyed, building is adornd
Face, finishing or other non-structural accessories etc. damage and to cause heavy losses or indoor expensive instrument, damage of facilities to cause serious
Loss or secondary disaster.In order to avoid the generation of above-mentioned disaster, people must control the earthquake response of structural system, and
Eliminate " amplifier " effect of structural system.
Early 20th century, the calculation method and help the seismic coefficient that wild sharp weapon doctor proposes that big gloomy professor Fang Ji of Japan proposes
Method does not account for the dynamic characteristics of structure, and the static(al) that successors are referred to as Aseismic Design is theoretical, be inclined in order to resist earthquake more
In using firm building structure, i.e., " rigid structural system ", but this structural system is difficult really to realize, also uneconomical,
Only the important building of only a few uses this structural system.With the development of society, building is more and more huger, complicated,
People have higher requirement to the safety of building, therefore to reach expected target of setting up defences in reasonable economic limit
More difficult, between safety and economy, people face dilemma.Secondly, people to the understanding of earthquake not enough, in advance
There are also certain distances with its practical earthquake response for geodesic structure object earthquake response, thus the earthquake resistant construction taken also not exclusively is closed
Reason.It is first in the 1950s, the M A Biot in the U.S. et al. proposition Aseismic Design that the first time of aseismic theory development, which is broken through,
Reacting spectrum theory.At this moment people start to consider the dynamic characteristics relationship between earthquake motion and building, propose " ductility construction
System ".Compared with earliest design method, Ductility Design Method already provided with the thought for carrying out " dredging " to energy, therefore it
It is scientific.However, works will terminate dynamic respons, energy conversion or consumption must be carried out.This antidetonation
Structural system, admissible structure and supporting member such as column, beam, node damage in earthquake, that is, rely on structure and load-bearing structure
The damage of part consumes most of energy, often leads to structural elements and seriously destroys or even collapse in earthquake, this is to a certain degree
On be it is unreasonable be also it is unsafe.With the progress of society and economic development, people are to antidetonation shock attenuation, windproof requirement
Higher and higher, certain important building such as commemorative architectures, decoration expensive modern architecture and nuclear power station etc. do not allow structure
Component enters inelastic state, makes the application of " ductility construction system " be increasingly subject to limit, these all become Structural Engineering technology
The real and great project that personnel face.Scholars are actively working to the exploration and research of new Aseismic Structure System,
Beauty in 1972 clearly proposes the concept of vibration control of civil engineering structure by scholar professor Yao Zhiping of Chinese origin for the first time.Yao Zhiping
Professor thinks that the performance of structure can be controlled by control means, so that they are able to maintain under environmental load effect one
In a specified range.To ensure safety, displacement structure needs to limit, and considers from the comfort aspect of occupant, and acceleration needs
Limitation.Vibration control of civil engineering structure can effectively mitigate structure and act in power such as earthquake, wind, vehicle, wave, stream, ice
Under reaction and damage accumulation, effectively improve structure shock resistance and combat a natural disaster performance.Aseismic theory enters one again in this way
New developing stage.
Energy-dissipating and shock-absorbing technology is one kind of passive control technology, it is that certain nonload bearing elements of structure are designed to energy dissipating
Component, or energy dissipation component is set at certain positions of structure.Under small shake effect, structure has enough bearing capacity and stiffness, energy
Meet the requirement of normal use.Under big shake effect, energy dissipation component generates biggish damping force, absorbs and a large amount of seismic energy that dissipates
Amount, reduces the dynamic response of main structure, achievees the purpose that reduce structural damage.Energy-dissipating and shock-absorbing technology is widely used in high level
Building, the antidetonation and wind resistance of towering structure and Loads of Long-span Bridges and the seismic hardening of existing structure etc..At present
Exploitation and with energy dissipator can be mainly divided into two major classes：One kind is energy-dissipating structure component, including Eccentric Steel Brace, side
Frame support and perps shear wall etc.；Another kind of is energy dissipation damper, including viscosity and viscoelastic damper, frcition damper, gold
Belong to damper etc..
Viscous damping wall is a kind of energy dissipative device for building structure, is Japanese scholars Arima and Miyazaki
Deng what is put forward in 1986, belong to one kind of velocity-dependent damper, it is by the box thin wall piece that is fixed on floor beam
It is inserted into the composition of the steel plate within box thin wall with wall top floor beam is fixed on, the viscous material of high viscosity is poured into wall piece, when
When relative displacement or speed occur for floor, steel plate slides in box thin viscous material within the walls, consumes ground by viscous damping
Energy is shaken, to reduce the earthquake response of structure.It has lot of advantages：It is easy to manufacture and install, do not need complicated device and
The active area of special material, wall and high viscous material is big, and the damping ratio of structure can be improved very much, absorbs largely
Shake energy；It is applied widely, do not influence the overall appearance of building.Viscous damping wall can be mounted on general tier building structure
In, while being also applied for high-rise and super-high building structure；Easy to maintenance, upkeep cost is low, moreover it can be used to seismic hardening and shake
After repair.
But viscous damping wall belongs to velocity-dependent damper, and speed associated damper has under small shake effect to be added well
Speed and story shearing force control effect, and being displaced relationship type damper has good Bit andits control effect under big shake effect, is
Realize the damping effect of moderately good floor acceleration, relative storey displacement and story shearing force, group speed relationship type and displacement
Relationship type effect can be more preferable.But steel plate is all monoblock type within the walls for most of viscosity dampings at present, is not easy to realize that displacement type damps
Device.
