Description
Technical field
The power consumption that the present invention relates to a kind of building structure is supported, and particularly relates to the constraint friction buckling-restrained energy-dissipation that a kind of building construction vibration is controlled.
Background technology
Earthquake disaster has sudden and crushing, and the safety of human life, property in serious threat.Ruinous earthquake nearly thousand times occur in the world every year, and a violent earthquake can cause the economic loss of more than one hundred billion dollar, causes hundreds of thousands people death or serious disability.China is located in the world on two most active earthquake zones, is one of the most serious country that suffers disaster from an earthquake, and the casualties that earthquake causes occupies first place in the world, and economic loss is also very huge.In earthquake the considerable damage of building with collapse, be the immediate cause that causes earthquake disaster.When earthquake occurs, ground vibration causes the earthquake response of structure.For basis, be fixed in the building structure on ground, its reaction is along successively amplifying highly 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 do not destroy, breaking-ups such as architectural coating, finishing or other non-structure accessory and cause heavy losses; Or indoor expensive instrument, damage of facilities cause serious loss or secondary disaster.For fear of 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 (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.), energy dissipator is installed.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; increase along with structure lateral deformation; energy dissipation component or energy dissipator take the lead in starting working; produce larger damping; a large amount of earthquakes that consume input structures or the wind energy that shakes; making the kinetic energy of structure or elastic potential energy homenergic change into the forms such as heat energy dissipates; the rapidly earthquake of attenuating structure or the wind reaction (displacement, speed, acceleration etc.) of shaking; make agent structure avoid occurring obvious inelastic state, 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.Energy dissipation component can be formed to various power consumptions supports for supporting, as cross support, diagonal brace support, the support of K shape etc.
At present the buckling-restrained energy-dissipation of 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 has been called " buckling-restrained energy-dissipation " patent of invention; China Patent No. 200910081817.5 discloses a kind of name and has been 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 has been called " compound energy-consumption supporting member of automatically recovering axis function placed in the middle " patent of invention etc.Yet the confined concrete of some buckling-restrained energy-dissipations is easy crushed, lose constraint and anti-buckling effect, caused its energy dissipation capacity significantly to reduce.Therefore, manufacturing process is supported in some power consumptions, and energy-dissipating property etc. still require further improvement.
Summary of the invention
The object of the present invention is to provide a kind of constraint friction buckling-restrained energy-dissipation, this supports and adopts the effectively mode of isolation, avoids confined concrete to destroy, to improve its energy dissipation capacity.The power consumption effect of utilization constraint friction buckling-restrained energy-dissipation can reduce the earthquake response of building structure, and building structure is played a very good protection.
In order to realize object of the present invention, the technical solution used in the present invention is:
