Description
Technical field
The invention belongs to building construction vibration control fields, reset high damping friction-type more particularly to a kind of limit and combine
Support.
Background technique
Earthquake disaster have it is sudden and crushing, seriously threaten the safety of human life, property.Annual hair in the world
Raw ruinous earthquake nearly thousand times, a violent earthquake can cause the economic loss of more than one hundred billion dollar, cause hundreds of thousands people dead or tight
It is severely injured residual.China is located on two most active earthquake zones in the world, is the one of the countries with the most serious ... that suffers disaster from an earthquake, earthquake
Caused by casualties occupy first place in the world, economic loss is also very huge.In earthquake the considerable damage of building with collapse, be to make
At the immediate cause of earthquake disaster.When earthquake occurs, ground vibration causes the earthquake response of structure.Ground is fixed in for basis
Building structure, reaction along highly from top to bottom successively amplification.Since the earthquake response of works a part (accelerates
Degree, speed or displacement) it is excessive, so that main body load-carrying members is seriously destroyed or even is collapsed；Although or main structure is not destroyed, is built
Facing, finishing or other non-structural accessories etc. is built to damage and lead to heavy losses；Or indoor expensive instrument, damage of facilities cause sternly
The loss or secondary disaster of weight.In order to avoid the generation of above-mentioned disaster, people must control the earthquake response of structural system
System, and eliminate " amplifier " effect of structural system, structure energy-eliminating shock-absorbing technology be certain nonload bearing elements of structure (such as
Shear wall, connector etc.) it is designed to energy dissipating rod piece, or at certain positions (interlayer space, node, connecting sewing etc.) of structure
Energy dissipator is installed.In small wind or small shake, these energy dissipating rod pieces (or energy dissipator) and structure itself have enough sides
To rigidity to meet requirement, structure is in elastic stage；When there is big shake or strong wind, with the increasing of structure lateral deformation
Greatly, energy dissipation component or energy dissipator take the lead in starting to work, and generate larger damping, a large amount of earthquakes for consuming input structure or wind shake energy
Amount, makes the energy such as kinetic energy or the elastic potential energy of structure be converted to the forms such as thermal energy and dissipates, the earthquake of rapid attenuating structure or wind
Vibration reaction (displacement, speed, acceleration etc.) makes main structure avoid the occurrence of apparent inelastic state, protects main structure
And component in macroseism or strong wind from destroy.It is that structure produces because the reasons such as earthquake are transferred to the external energy of building structure
The root of raw vibration increases energy consumption, it will reduce the dynamic respons of structure so energy-consuming device is arranged in the structure.At present
The confined concrete of the anti-buckling energy-consumption component of research and development is easily crushed and loses constraint and anti-buckling effect, causes it
Energy dissipation capacity is greatly reduced.Therefore, some dissipative member manufacturing process, there is still a need for further improvements for energy-dissipating property etc..
