Description
Technical field
The present invention relates to a kind of energy dissipation brace of building structure, particularly relate to the channel-section steel isolation buckling-restrained energy-dissipation 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.Due to the earthquake response of works a part, acceleration, speed or displacement are excessive, and 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 some nonload bearing element structure, and as support, shear wall, connector etc. are designed to energy dissipating rod member, or at some position of structure, interlayer space, node, connecting sewing etc. install energy dissipator.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, a large amount of consume input structure earthquake or wind to 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 occurring 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, 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 buckling-restrained energy-dissipation 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 the confined concrete of some buckling-restrained energy-dissipations easily crushed and lose constraint with anti-buckling effect, cause its energy dissipation capacity significantly to reduce.Therefore, some energy dissipation brace manufacturing process, energy-dissipating property 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 rational in infrastructure, cost is low, adopt the mode of effectively isolation, avoid confined concrete to destroy, to improve its energy dissipation capacity.The power consumption effect utilizing channel-section steel to isolate buckling-restrained energy-dissipation can reduce the earthquake response of building structure, to the channel-section steel isolation buckling-restrained energy-dissipation that building structure plays a very good protection.
The technical scheme of technical solution problem of the present invention is to achieve these goals:
