Description
Technical field
The present invention relates to a kind of building construction vibration control device, particularly relate to a kind of close hole of for building close plate viscous damper of building construction vibration control.
Background technology
Earthquake disaster has sudden and crushing, and the safety of human life, property in serious threat.Ruinous earthquake nearly thousand times occur in the world every year, and a violent earthquake can cause the economic loss of more than one hundred billion dollar, causes hundreds of thousands people death or serious disability.China is located in the world on two most active earthquake zones, is one of the most serious country that suffers disaster from an earthquake, and the casualties that earthquake causes occupies first place in the world, and economic loss is also very huge.In earthquake the considerable damage of building with collapse, be the immediate cause that causes earthquake disaster.When earthquake occurs, ground vibration causes the earthquake response of structure.Be fixed in the building structure on ground for basis, its reaction is along successively amplifying highly from top to bottom.Because the earthquake response (acceleration, speed or displacement) of works a part is excessive, the heavy damage of main body load-carrying members is even collapsed; Or although agent structure do not destroy, breaking-ups such as architectural coating, finishing or other non-structure accessory and cause heavy losses; Or indoor expensive instrument, damage of facilities cause serious loss or secondary disaster.For fear of the generation of above-mentioned disaster, people must control the earthquake response of structural system, and eliminate " amplifier " effect of structural system.
20 beginnings of the century, the seismic Calculation method that large gloomy professor Fang Ji of Japan proposes and the seismic coefficient method of helping wild sharp weapon doctor proposition are not all considered the dynamic characteristics of structure, successors are referred to as the static(al) theory of seismic design, in order to resist earthquake, tend to adopt firm building structure more, i.e. " rigid structural system ", but this structural system is difficult to real realization, also uneconomical, only have the important building of only a few to adopt this structural system.Along with social development, building is more and more huger, complicated, and people have had higher requirement to the safety of building, and the target of setting up defences that therefore will reach expection in rational economic limit is more difficult, between safety and economy, people face dilemma.Secondly, to the understanding of earthquake not enough, predict thing earthquake response earthquake response actual with it also has certain gap to people, thereby the seismic measures of taking also not exclusively rationally.The people such as the breakthrough for the first time of antidetonation theoretical developments is in early 1950s, the M A Biot of the U.S. propose the reacting spectrum theory of seismic design.At this moment people start to consider the dynamic characteristics relation between earthquake motion and building, have proposed " ductility structural system ".Compare with method for designing the earliest, Ductility Design Method is with the thought of energy being carried out to " dredging ", and therefore it has certain science.But works will stop vibration reaction, must carry out power conversion or consumption.This Aseismic Structure System, damaging appears in admissible structure and supporting member (post, beam, node etc.) in earthquake, rely on the damage of structure and supporting member to consume most of energy, often cause structural element heavy damage in earthquake even to be collapsed, this be to a certain extent unreasonable be also unsafe.Along with social progress and expanding economy, people require also more and more higher to antidetonation shock attenuation, windproof, some important building (as memorial architecture, decorate expensive modern architecture and nuclear power station etc.) does not allow structural element to enter inelastic state, the application of " ductility structural system " is restricted day by day, and these all become reality that Structural Engineering technician faces and great problem.Various countries scholar is actively devoted to exploration and the research of new Aseismic Structure System, and within 1972, U.S. mat scholar Yao Zhiping (J T P Yao) professor of Chinese origin has clearly proposed the concept of vibration control of civil engineering structure for the first time.Yao thinks that the performance of structure can be controlled by control device, so that they under environmental load effect, can remain in the scope of an appointment, for guaranteeing safety, displacement structure needs restriction, considers from occupants's comfort aspect, and acceleration needs restriction.Vibration control of civil engineering structure can alleviate reaction and the damage accumulation of structure under the dynamic actions such as earthquake, wind, vehicle, wave, stream, ice effectively, effectively improves the shock resistance of structure and combats a natural disaster performance.Antidetonation theory enters again a new developing stage like this.
Viscous damper is according to fluid motion, and particularly when fluid can produce during by throttle orifice, the principle of viscosity resistance makes.It is one and rigidity, velocity correlation type damper.Be widely used in the fields such as highrise building, bridge, building structure aseismatic transformation, industrial pipeline equipment antivibration, military project.General oil damper replaces hydraulic giant cylinder and depression bar with oil cylinder and the piston of steel.And tiny oilhole is set on piston, replace the outlet of water.In the time that oil body passes through narrow and small damping hole, the energy that damper absorbs is resisted and is converted to heat energy by fluid.
At present the viscous damper of research and development has China Patent No. 201110324602.9 to disclose a kind of name to be called " a kind of online adjustable damping viscous damper " patent of invention; China Patent No. 200810040841.X discloses the patent of invention that a kind of name is called " with the viscous damper of axially stop block "; China Patent No. 200810040842.4 discloses a kind of name and has been called " with the viscous damper of radial limiting device " patent of invention; China Patent No. 200910027946.6 discloses the patent of invention that a kind of name is called " spiral-hole type viscous damper "; China Patent No. 200910027945.1 discloses a kind of name and has been called " controllable viscous damper " patent of invention; China Patent No. 201010136260.3 discloses the patent of invention that a kind of name is called " Shaftless anti-leakage viscous damper "; China Patent No. 201010293529.9 discloses a kind of name and has been called " a kind of viscous damping limit method and viscous damper with stopper " patent of invention; China Patent No. 201010282535.4 discloses the patent of invention that a kind of name is called " a kind of viscous damper ".
When damping hole diameter one timing that oil body passes through, the resistance of oil damper is roughly proportional with 2 powers of loading velocity.Oil damper, by the combination of various pressure regulator valves and dropping valve, can produce the product of the resistance with various characteristics.But on the other hand, because component of machine quantity increases, reliability reduces, it is large that the possibility of the problem such as easily break down becomes.
