Description

The plumbous stacked ring shape of steel damper
Technical field
The present invention relates to a kind of building structure vibrations control device, particularly relate to the plumbous stacked ring shape of the construction steel damper that a kind of building structure vibrations are controlled.
Background technology
Structure energy-eliminating shock-absorbing technology is that some nonload bearing element (as support, shear wall, connector etc.) of bar structure is designed to energy dissipating rod member, or at some position of structure, interlayer space, node, connecting sewing etc., install energy dissipator.In the time of little wind or little shake, these energy dissipating rod members or energy dissipator and structure itself have enough lateral rigidities to meet instructions for use, make structure in elastic stage; In the time there is large shake or strong wind; along with the increase of structure lateral deformation; energy dissipation component or energy dissipator take the lead in starting working; produce larger damping, consume in a large number the earthquake of input structure or the wind energy that shakes, make the kinetic energy of structure or elastic potential energy homenergic change into the forms such as heat energy and dissipate; the rapidly earthquake of attenuating structure or the wind reaction of shaking; displacement, speed, acceleration etc., make agent structure avoid occurring obvious inelastic state, and protection agent structure and member exempt from destruction in macroseism or strong wind.Because the reasons such as earthquake are transferred to the external energy of building structure, be the root of structure generation vibration, so energy-dissipating device is set in structure, increase energy consumption, will reduce the vibration reaction of structure.
Metallic damper (metallic yielding damper) is the various forms of damping energy dissipation devices of making by mild steel or other softer metals.After metal yield, have good Hysteresis Behavior, the elastoplasticity hysteresis distortion power consumption that utilizes some metal to have, comprises mild steel damper, lead damper and marmem (shape memory alloys is called for short SMA) damper etc.The mechanism that it carries out vibration isolation to structure is that the portion of energy of structural vibration is dissipated by the surrender hysteretic energy of metal, thereby reaches the object that reduces structural response.
Mild steel damper is to make full use of after mild steel enters the plastic stage to have good hysteretic characteristic.1972, first the American scholar such as Kelly and Skinner began one's study and utilize this performance of mild steel to carry out the dynamic response of control structure, and proposed several forms of mild steel damper, comprised 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, wherein relatively more typical in X-shaped mild steel damper, 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 subject to the features such as environment, temperature affect, 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 large, fusing point is low, plasticity is high, intensity is low, corrosion resistant is strong, lubricating ability is strong, simultaneously owing to thering is higher ductility and flexibility, so can absorb a large amount of energy in deformation process, and there is stronger distortion follow-up control, and by dynamic recovery and recrystallization process, its tissue and performance also can return to the state before distortion, therefore lead damper have that application life is unrestricted, the damping that provides reliable, to not needing 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 large, damping capacity is strong and durability, corrosion resistance, the advantage such as anti-fatigue performance is good, operating temperature range is large and maintenance cost is low.
At present the steel lead damper of research and development has China Patent No. 200510033467.7 to disclose a kind of name to be called " steel-lead combined energy comsuming device " patent of invention; China Patent No. 201010282519.5 discloses the patent of invention that a kind of name is called " a kind of steel lead damper "; China Patent No. 201110318337.3 discloses the patent of invention that a kind of name is called " the plumbous tension and compression damper of steel "; These dampers all can not perform well in shearing the power consumption of force part.But these invention structure relative complex.
Summary of the invention
The present invention is directed to the technical problem of above-mentioned existence; object is to provide that a kind of stock utilization is high, energy consumption effect good; while use, can increase the integral rigidity of building structure under normal condition; and in the time running into earthquake; utilize the surrender power consumption of the plumbous stacked ring shape of steel damper can reduce the earthquake response of building structure, the plumbous stacked ring shape of the steel that building structure is played a very good protection damper.
The technical scheme of technical solution problem of the present invention is to achieve these goals:
The plumbous stacked ring shape of steel damper, comprising: mild-steel energy-consumption cylinder, lead loss energy cylinder and steel support, and its mild-steel energy-consumption cylinder and lead loss can the placement of cylinder alternative stacked form power consumption cylinder; The junction plate of square tube shape is waled the power consumption position of power consumption cylinder, and four junction plates are symmetrical between two with respect to power consumption Tong center, and form " X " shape, are connected respectively with each fixed head of screw with each junction plate.
Described fixed head adopt bolt respectively with steel support and connection.
The present invention compared with prior art has following advantages and effect:
The present invention is owing to adopting mild-steel energy-consumption cylinder and lead loss to place formation power consumption cylinder by cylinder lamination; junction plate adopts square tube shape that power consumption position is waled; four junction plates are symmetrical between two with respect to power consumption Tong center; and form " X " shape; be installed in framework " X " support; while use, can increase the integral rigidity of building structure under normal condition; and in the time running into earthquake; utilize the surrender power consumption of the plumbous stacked ring shape of steel damper can reduce the earthquake response of building structure, building structure is played a very good protection.
The plumbous stacked ring shape of steel of the present invention damper initial stiffness is larger, material yield disperses area large, without obvious stress concentration phenomenon, mild-steel energy-consumption cylinder and lead loss can have good harmony by cylinder, stock utilization is high, energy consumption effect good, the fabrication and installation of the plumbous stacked ring shape of steel damper are simultaneously simple, easy to use, both can, for the seismic design of new building engineering, also can keep in repair for the reinforcing of existing engineering.
