Description

A kind of huge support of multistage multiple anti-buckling large power consumption and processing method thereof
Technical field
The invention belongs to technical field of buildings, particularly relate to the huge support of multistage multiple anti-buckling large power consumption and the processing method thereof of the control of a kind of building construction vibration.
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.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, 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, avoid agent structure and component to be destroyed 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.Be used for by energy dissipation component can forming various energy dissipation brace in support, as cross support, diagonal brace supports and K shape supports.
The patent of the buckling-restrained energy-dissipation of current research and development has: China Patent No. 200710062637.3 discloses a kind of name and is 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.
