Description
Technical field
The present invention relates to a kind of building structure vibrations control device, particularly relate to a kind of rib mild steel damper for building compound with holes of building structure vibrations control.
Background technology
Because metal material enters plasticity and has later on good Hysteresis Behavior, thereby is used to make various types of energy-dissipating devices.A kind of passive energy-consumption shock-absorption device that the metal damper device is generally assembled by low-yield or extremely low yield point steel plate and its positioner.Its Seismic mechanism is simple, and cost is low, and effect is remarkable, and simultaneously, energy-dissipating device generally is to be installed in the structure as nonload bearing element, and under normal operating condition, it can improve the integral rigidity of structure; Under little earthquake situations condition, building structure itself just can be satisfied requirements for fortification against earthquake, this moment structure the distortion less, metal damper does not enter or enters the plastic stage than small part; When running into large shake or rarely occurred earthquake, metal damper will rate be introduced into the plastic stage, relies on the plasticity of its generation can reduce the earthquake response of structure, and its destruction can not affect integrally-built use.The seismic design that energy-dissipating device both can be used for the new construction structure also can for the reinforcing maintenance of existed building, have good economic benefit.
Mild steel damper is to take full advantage of to have good hysteretic characteristic after mild steel enters the plastic stage.1972, at first the begin one's study this performance of utilizing mild steel of the American scholar such as Kelly and Skinner was come the dynamic response of control structure, and proposes several forms of mild steel damper, comprises torsion beam, bent beam, U-shaped bar energy consumer etc.Subsequently, other scholar proposes again the different mild steel damper of many forms in succession, and is wherein relatively more typical in X-shaped, triangular plate mild steel damper, E shaped steel damper, C shaped steel damper.Through domestic and international many scholars' theoretical and experimental study, confirm that mild steel damper has stable hysteretic characteristic, good low cycle fatigue property, long-term reliability and be not subjected to the characteristics such as environment, temperature effect is a kind of up-and-coming energy consumer.
At present the mild steel damper of research and development has China Patent No. 200410020892.8 to disclose a kind of name to be called " double-X type flexible steel damper " patent of invention; China Patent No. 200410020893.2 discloses the patent of invention that a kind of name is called " circular hole type flexible steel damper "; China Patent No. 201010556734.X discloses the patent of invention that a kind of name is called " grading yield type mild steel damper ".
Yet after the stressed surrender of some mild steel dampers, local stress and strain concentration phenomenon are serious, cause damper plasticity skewness, do not give full play to the potential of material.
Summary of the invention
Provide a kind of compound rib mild steel damper with holes order of the present invention, by in the damper internal openings, not only save material, make the power consumption of damper more abundant; In addition, adopt a plurality of damper mild steel sheets to unite use, increased the out of plane stiffness of damper, be unlikely to unstability outside the plane before damper is fully consumed energy.The object of the present invention is to provide a kind of multiple arched porous metal damper; being installed on the framework herringbone supports; can increase the integral rigidity of building structure when under normal condition, using; and when running into earthquake; utilize the surrender power consumption of multiple arched porous metal damper can reduce the earthquake response of building structure, building structure is played a very good protection.
Technical scheme is as follows: compound rib mild steel damper with holes, mainly by the power consumption position, divide the rib hole, the rib mesopore, vertical power consumption rib, level power consumption rib, fixed position, screw, billet, angle steel, set bolt, girder steel, the herringbone support, top, channel-section steel, the compositions such as nuts and bolt, it is characterized in that: the power consumption position be rectangle and in a plurality of minutes rib holes are set, dividing the rib hole is that ellipse and major axis are vertically arranged, the position of will consuming energy is divided into a plurality of vertical power consumption ribs, in each vertical power consumption rib, the rib mesopore is set, the rib mesopore is oval, and major axis horizontal arrangement, a plurality of rib mesopores are divided into a plurality of vertical power consumption ribs and level power consumption rib with a vertical power consumption rib, fixed position is rectangular in form, bolt hole is set therein, adopt two or multi-disc mild steel damper to assemble, between the fixed position (6) of each damper, billet (8) is set respectively, two fixed positions are connected with the herringbone support, top with girder steel respectively, connected mode is with bolts, with bolt channel-section steel is connected with the herringbone support, top with girder steel respectively.Girder steel is connected 12 with the herringbone support, top) be connected both sides employing angle steel with fixed position as backing plate
Advantage of the present invention and beneficial effect:
Compound rib mild steel damper initial stiffness with holes is large, without obvious stress concentration phenomenon, steel surrender area is large, energy consumption effect good, steel utilization ratio is high; The out of plane stiffness of damper is large, is unlikely to unstability outside the plane before damper fully consumes energy, and has guaranteed that damper is unlikely to destroyed when stressed outside larger plane.In addition, the making of compound rib mild steel damper with holes, install simply, easy to use, both can be used for the seismic design of new building engineering, also can be used for the reinforcing maintenance of existing engineering.When being subject to horizontal seismic force, compound rib mild steel damper with holes is subject to the horizontal shear effect.Not only save material, make the power consumption of damper more abundant.Therefore utilize the surrender power consumption of compound rib mild steel damper with holes can reduce the earthquake response of building structure, building structure is played a very good protection.
