Description

A kind of multistage multiple anti-buckling huge support of big power consumption and processing method thereof
Technical field
The invention belongs to technical field of buildings, particularly relate to the multistage multiple anti-buckling huge support of big power consumption and processing method thereof that a kind of building construction vibration controls.
Background technology
Earthquake disaster has sudden and crushing, and the safety of human life, property in serious threat.Ruinous earthquake nearly thousand times occurs the most every year, and a violent earthquake can cause the economic loss of more than one hundred billion dollar, causes hundreds of thousands people dead or severe 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 the hugest.In earthquake the considerable damage of building with collapse, be the immediate cause causing earthquake disaster.When earthquake occurs, ground vibration causes the earthquake response of structure.Basis being fixed in the building structure on ground, its reaction is along the most successively amplifying.Owing to the earthquake response (acceleration, speed or displacement) of works a part is excessive, main body load-carrying members heavy damage is made even to collapse;Although or agent structure do not destroys, but architectural coating, finishing or other non-structural accessory etc. damage and cause heavy losses;Or the expensive instrument in indoor, damage of facilities cause serious loss.In order to avoid the generation of above-mentioned disaster, the earthquake response of structural system must be controlled by people, and eliminates " amplifier " effect of structural system.
Structure energy-eliminating shock-absorbing technology is that some nonload bearing element (such as support, shear wall, connector etc.) structure 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 big shake or strong wind occur, increase along with structure lateral deformation, energy dissipation component or energy dissipator take the lead in starting working, produce bigger damping, a large amount of earthquakes consuming input structures or wind shake energy, the kinetic energy or the elastic potential energy homenergic that make structure change into the forms such as heat energy and dissipate, the earthquake of rapid attenuating structure or Wind Vibration Response (displacement, speed, acceleration etc.), agent structure is made to avoid the occurrence of obvious inelastic state, it is to avoid agent structure and component are destroyed in macroseism or strong wind.Because the reasons such as earthquake are transferred to the external energy of building structure, being that structure produces the root vibrated, so arranging energy-dissipating device in the structure, increasing energy consumption, it will reduce the dynamic respons of structure.Various energy dissipation brace can be formed, such as cross support, diagonal brace support and K shape support etc. in being used for energy dissipation component supporting.
The patent of the buckling-restrained energy-dissipation of research and development has at present: China Patent No. 200710062637.3 discloses a kind of entitled " steel tube anti-flex energy dissipation support " patent of invention;China Patent No. 200810204340.0 discloses a kind of entitled " buckling-restrained energy-dissipation " patent of invention;China Patent No. 200910081817.5 discloses a kind of entitled " a kind of all-steel buckling-preventing energy-consuming brace " patent of invention;China Patent No. 200910226690.1 discloses a kind of entitled " 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 is easily crushed and loses constraint and anti-buckling effect, causes its energy dissipation capacity to be greatly reduced.Therefore, some energy dissipation brace manufacturing process, energy-dissipating property etc. remains a need for improving further.
