Description

Intersect and strengthen steel plate anti-buckling energy-consumption wall
Technical field
The present invention relates to a kind of Wasted-energy steel plate wall of building structure, the intersection that particularly relates to a kind of building structure is strengthened steel plate anti-buckling energy-consumption wall.
Background technology
Earthquake disaster has sudden and crushing, and the safety of human life, property in serious threat.Annual failure earthquake is nearly thousand times in the world, and a violent earthquake can cause the economic loss of more than one hundred billion dollar, causes the hundreds of thousands people dead or serious wounded or disabled.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 the earthquake considerable damage of building with collapse, be the immediate cause that causes earthquake disaster.When earthquake occured, ground vibration caused the earthquake response of structure.Be fixed in the building structure on ground for the 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, makes the heavy damage of main body load-carrying members even collapse; Although or agent structure do not destroy, the breaking-up 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 computational methods 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, people were referred to as the static(al) theory of seismic design afterwards, 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 the realization, also uneconomical, only have the important building of only a few to adopt this structural system.Development along with society, building is more and more huger, complicated, and people have had higher requirement to 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, people to the understanding of earthquake not enough, predict thing earthquake response earthquake response actual with it also has certain distance, thereby the seismic measures of taking is also not exclusively reasonable.Break through the first time of antidetonation theoretical developments is in early 1950s, and the people such as the M A Biot of the U.S. propose the reacting spectrum theory of seismic design.At this moment people begin to consider that the dynamic characteristics between earthquake motion and the building concerns, have proposed " ductility structural system ".Compare with method for designing the earliest, Ductility Design Method is with the thought of energy being carried out " dredging ", so it has certain science.Yet works will stop the vibration reaction, must carry out power conversion or consumption.This Aseismic Structure System, damaging appears in earthquake in admissible structure and supporting member (post, beam, node etc.), namely rely on the damage of structure and supporting member to consume most of energy, often cause structural element heavy damage even collapse in earthquake, this be to a certain extent unreasonable also be unsafe.Progress and expanding economy along with society, people require also more and more higher to antidetonation shock attenuation, windproof, some important building (such as memorial architecture, the modern architecture of decorating costliness 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 the Structural Engineering technician faces and great problem.The various countries scholar actively is devoted to exploration and the research of new Aseismic Structure System, and U.S. mat scholar Yao Zhiping of Chinese origin (J T P Yao) professors in 1972 have 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 the 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.The antidetonation theory has entered again a new developing stage like this.
Steel plate shear wall structure is a kind of novel lateral resisting structure system that grows up in the 70's of 20th century.Steel plate shear force wall is made of embedded steel plate, vertical edges member (post) and horizontal edge member (beam), its holistic resistant behavior is similar to the vertical semi girder of bottom build-in, wherein the vertical edges member is equivalent to flange of beam, embedded steel plate is equivalent to web, and the horizontal edge member can Approximate Equivalent be transverse stiffener then.Embedded steel plate can adopt without stiffening rib and the structural form that stiffening rib is arranged.Under severe earthquake action, can take full advantage of the Post-Bucking Strength of steel plate without the steel plate shear force wall of putting more energy into, and have good ductility and energy dissipation capacity.The steel plate shear force wall of putting more energy into then can limit flexing outside the plane of steel plate, thereby improves the flexing bearing capacity of structure, helps to strengthen lateral deformation stiffness and the convenient construction of structure under wind and little shake effect.Add concrete shear wall structure system with traditional steel frame or steel frame and compare, steel plate shear wall structure has thin thickness, from heavy and light, the advantage such as construction speed is fast and ductility is good.Existing achievement in research and case history show, steel plate shear force wall is a kind of Lateral Resistant System that has very much development potentiality, is particularly useful for high-intensity earthquake set up defences highrise building and the seismic hardening in district.In the past few decades, the various countries scholar has carried out the research of many tests and theoretical side to this structure.These researchs have all obtained common conclusion: this structural elasticity initial stiffness is high, displacement ductility is large, Hysteresis Behavior is stable.
At present the Wasted-energy steel plate wall of research and development has China Patent No. 200810034557.1 to disclose a kind of name to be called " high-rise vertical shearing energy-consuming steel plate wall structure system " patent of invention.
Yet some Wasted-energy steel plate walls easily produce flexing at present, also have the plasticity distribution of some Wasted-energy steel plate walls more concentrated, are unfavorable for power consumption, all need to be solved preferably.
