Abstract

The present invention discloses a kind of waveform mild steel energy dissipation support.It comprises lamination waveform mild steel plate, fixed part and stirrup, the large waveform portion that lamination waveform mild steel plate described in it is made up of at least two-layer mild steel plate and small form part are formed, described large waveform portion and small form part mutually replace and direction is contrary, two lamination waveform mild steel plates are symmetrical arranged, small form part contacts with each other, and is equipped with stirrup in each small form part; Symmetrically arranged lamination waveform mild steel plate two ends connect and compose by small echo part and fixed part.The present invention owing to have employed two symmetrically arranged modes of lamination waveform mild steel plate, such that the plasticity of structure of the present invention distributes rationally, energy dissipation capacity is good, it is simple, easy for installation to process.Having good anti-seismic performance, ductility and hysteretic energy ability, is a kind of superior energy dissipation component.

Description

Waveform mild steel energy dissipation support
Technical field
The present invention relates to a kind of energy dissipation brace of building structure, particularly relate to the waveform mild steel energy dissipation support that a kind of building construction vibration controls.Belong to Structural Engineering field.
Background technology
Earthquake disaster has sudden and crushing, and the safety of human life, property in serious threat.Every year ruinous earthquake nearly thousand times occur in the world, a violent earthquake can cause the economic loss of more than one hundred billion dollar, causes hundreds of thousands people death or severe disability.China is located in the world on two most active earthquake zones, and be one of the most serious country that suffers disaster from an earthquake, the casualties that earthquake causes occupies first place in the world, and economic loss is also very huge.In earthquake building considerable damage with collapse, be the immediate cause causing earthquake disaster.When earthquake occurs, ground vibration causes the earthquake response of structure.Basis is fixed in the building structure on ground, its reaction is along highly successively amplifying 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 is not destroyed, architectural coating, finishing or other non-structural accessory etc. damage and cause heavy losses; Or indoor expensive instrument, damage of facilities cause serious loss or secondary disaster.In order to avoid the generation of above-mentioned disaster, people must control the earthquake response of structural system, and eliminate " amplifier " effect of structural system.
Structure energy-eliminating shock-absorbing technology is that some nonload bearing element of structure (as support, shear wall, connector etc.) is designed to energy dissipating rod member, or installs energy dissipator at some position (interlayer space, node, connecting sewing etc.) of structure.When 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, and structure is in elastic stage; When 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; the earthquake of a large amount of consumption input structure or wind shake energy; make the kinetic energy of structure or elastic potential energy homenergic change into the forms such as heat energy to dissipate; the earthquake of rapid attenuating structure or Wind Vibration Response (displacement, speed, acceleration etc.); make agent structure avoid occurring obvious inelastic state, 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, be the vibrative root of structure, so arrange energy-dissipating device in the structure, increase energy consumption, the dynamic respons of structure will be reduced.Energy dissipation component is used in support, various energy dissipation brace can be formed, as cross support, diagonal brace support, K shape support.
The energy dissipation brace of current research and development has China Patent No. 200710062637.3 to disclose a kind of name to be called " steel tube anti-flex energy dissipation support " patent of invention; China Patent No. 200810204340.0 discloses a kind of name and is called " buckling-restrained energy-dissipation " patent of invention; China Patent No. 200910081817.5 discloses a kind of name and is called " a kind of all-steel buckling-preventing energy-consuming brace " patent of invention; China Patent No. 200910226690.1 discloses a kind of name and is called " compound energy-consumption supporting member of automatically recovering axis function placed in the middle " patent of invention etc.But some energy dissipation brace manufacturing process at present, energy-dissipating properties etc. still require further improvement.
Summary of the invention
The present invention is directed to the technical problem of above-mentioned existence, provide a kind of earthquake response utilizing the power consumption effect of waveform mild steel energy dissipation support can reduce building structure, the techniques such as the energy dissipation capacity of raising structure and making and installation.And simple and reasonable for structure, cost is low, to the waveform mild steel energy dissipation support that building structure plays a very good protection.
The technical scheme of technical solution problem of the present invention is to achieve these goals:
Waveform mild steel energy dissipation support, comprise: lamination waveform mild steel plate, fixed part and stirrup, the large waveform portion that lamination waveform mild steel plate described in it is made up of at least two-layer mild steel plate and small form part are formed, described large waveform portion and small form part mutually replace and direction is contrary, two lamination waveform mild steel plates are symmetrical arranged, small form part contacts with each other, and is equipped with stirrup in each small form part; Symmetrically arranged lamination waveform mild steel plate two ends connect and compose by small echo part and fixed part.
Described fixed part is provided with bolt hole; With bolts with beam column component, form bearing diagonal, herringbone supports or cross support.
The present invention compared with prior art has following advantages and effect:
The present invention owing to have employed two symmetrically arranged modes of lamination waveform mild steel plate, such that the plasticity of structure of the present invention distributes rationally, energy dissipation capacity is good, it is simple, easy for installation to process.Having good anti-seismic performance, ductility and hysteretic energy ability, is a kind of superior energy dissipation component.
