Description
Technical field
The present invention relates to a kind of building structure shake control device, particularly relate to the construction(al)steel lead lamination ring damper of a kind of building structure shake control.
Background technology
Structure energy-eliminating shock-absorbing technology is that some nonload bearing element (such as support, shear wall, connector etc.) structure is designed to energy dissipating rod member, or some position in structure, interlayer space, node, connecting sewing etc., installs energy dissipator.When little wind or little shake, these energy dissipating rod members or energy dissipator and structure itself have enough lateral rigidities with satisfied use requirement, make structure be in elastic stage；When big shake or strong wind occur; increase along with structure lateral deformation; energy dissipation component or energy dissipator take the lead in starting working; producing bigger damping, a large amount of earthquakes consuming input structures or wind shake energy, make the kinetic energy of structure or elastic potential energy homenergic change into the forms such as heat energy and dissipate; the earthquake of rapid attenuating structure or Wind Vibration Response; displacement, speed, acceleration etc., make agent structure avoid the occurrence of obvious inelastic state, and protection agent structure and component exempt from destruction in macroseism or strong wind.Because the reasons such as earthquake are transferred to the external energy of building structure, being that structure produces the root vibrated, so arranging energy-dissipating device in the structure, increasing energy consumption, it will reduce the dynamic respons of structure.
Metallic damper (metallic yielding damper) is the various forms of damping energy dissipation devices made by mild steel or other softer metals.There is after metal yield good Hysteresis Behavior, utilize the elastoplasticity hysteresis deformation power consumption that some metal has, including mild steel damper, lead damper and marmem (shape memory alloys is called for short SMA) antivibrator etc..It carries out the mechanism of vibration control to structure is the portion of energy of structural vibration to be dissipated by the surrender hysteretic energy of metal, thus reaches to reduce the purpose of structural response.
Mild steel damper is to make full use of after mild steel enters the plastic stage to have good hysteretic characteristic.1972, the American scholar such as Kelly and Skinner was first begin to this performance of research and utilization mild steel and carrys out the dynamic response of control structure, and proposes several forms of mild steel damper, including torsion beam, bent beam, U-shaped bar energy consumer etc..Subsequently, other scholar proposes the mild steel damper that many forms are different the most in succession, wherein than more typical such as X-shaped mild steel damper, triangular plate mild steel damper, E shape steel damper, C-type steel antivibrator.Theoretical and experimental study through many scholars both at home and abroad, it was demonstrated that mild steel damper has a stable hysteretic characteristic, good low cycle fatigue property, long-term reliability and not by features such as environment, temperature are affected, is a kind of up-and-coming energy consumer.
Lead damper is to make full use of lead to have the features such as density is big, fusing point is low, plasticity is high, intensity is low, corrosion resistant is strong, lubricating ability is strong, simultaneously because have higher ductility and flexibility, so substantial amounts of energy can be absorbed in deformation process, and there is stronger deformation tracking ability, and by dynamic recovery and recrystalline process, its tissue and performance also can be recovered to the state before deforming, and therefore lead damper has that the damping that service life is unrestricted, provide is reliable, need not the advantages such as maintenance in displacement sensitive, simple structure, work.But it has the shortcomings such as restorative difference and lead contamination.
All metal damper has that recoverable deformation is big, damping capacity strong and durability, corrosion resistance, the advantage such as anti-fatigue performance is good, operating temperature range is big and maintenance cost is low.
The steel lead damper of research and development has China Patent No. 200510033467.7 to disclose a kind of entitled " steel-lead combined energy comsuming device " patent of invention at present；China Patent No. 201010282519.5 discloses the patent of invention of a kind of entitled " a kind of steel lead damper "；China Patent No. 201110318337.3 discloses the patent of invention of a kind of entitled " steel lead pull-press antivibrator "；These antivibrators all can not perform well in shearing the power consumption of force part.But these invention structures are relative complex.
Summary of the invention
The present invention is directed to the technical problem of above-mentioned existence; purpose is to provide a kind of stock utilization height, energy consumption effect good; the integral rigidity of building structure can be increased when using in normal state; and when running into earthquake; the surrender power consumption utilizing steel lead lamination ring damper can reduce the earthquake response of building structure, the steel lead lamination ring damper playing a very good protection building structure.
The present invention solves the technical scheme of technical problem and is to achieve these goals:
Steel lead lamination ring damper, including: mild-steel energy-consumption cylinder, lead loss energy cylinder and bracing members, its mild-steel energy-consumption cylinder and lead loss energy cylinder alternative stacked are placed and are constituted power consumption cylinder；The power consumption position of power consumption cylinder is waled by the connecting plate of square tube shape, and four connecting plates are the most symmetrical relative to the center of power consumption cylinder, and constitute an X-shaped, and each fixed plate with screw is connected with each connecting plate respectively.
Described fixed plate uses bolt to be connected with bracing members respectively.
The present invention compared with prior art has following advantages and an effect:
Due to the fact that employing mild-steel energy-consumption cylinder and lead loss energy cylinder lamination are placed and constitute power consumption cylinder; connecting plate uses square tube shape to be waled at power consumption position; four connecting plates are the most symmetrical relative to the center of power consumption cylinder; and constitute an X-shaped; it is installed in framework " X " support; the integral rigidity of building structure can be increased when using in normal state; and when running into earthquake; the surrender power consumption utilizing steel lead lamination ring damper can reduce the earthquake response of building structure, plays a very good protection building structure.
Steel lead lamination ring damper initial stiffness of the present invention is bigger, material yield diffusional area is big, without obvious stress concentration phenomenon, mild-steel energy-consumption cylinder and lead loss energy cylinder have preferable harmony, stock utilization is high, energy consumption effect fabrication and installation good, steel lead lamination ring damper simultaneously are simple, easy to use, both may be used for the Aseismic Design of new building engineering, it is also possible to for the reinforcing maintenance of existing engineering.
