Description

Combined steel plate energy dissipation brace

Technical field

The utility model belongs to building construction vibration control field, more particularly to a kind of combined steel plate energy dissipation brace.

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.In earthquake the considerable damage of building with collapse, be the immediate cause for causing earthquake disaster.When earthquake occurs, ground Vibration causes the earthquake response of structure.It is fixed in the building structure on ground for basis, reacts along highly from top to bottom Successively amplification.Since the earthquake response (acceleration, speed or displacement) of works a part is excessive, make main body load-carrying members Serious destroy even is collapsed；Or although main structure is not destroyed, architectural coating, finishing or other non-structural accessories etc. damage and Lead to heavy losses；Or indoor expensive instrument, damage of facilities lead to serious loss or secondary disaster.In order to avoid above-mentioned disaster Generation, people must control the earthquake response of structural system, and eliminate " amplifier " effect of structural system, structure Energy-eliminating shock-absorbing technology be certain nonload bearing elements (such as shear wall, connector) of structure are designed to energy dissipating rod piece, or Certain positions (interlayer space, node, connecting sewing etc.) of structure are installed by energy dissipator.In small wind or small shake, these disappear Energy rod piece (or energy dissipator) and structure itself have enough lateral rigidities to meet requirement, and structure is in elastic shape State；When there is big shake or strong wind, with the increase of structure lateral deformation, energy dissipation component or energy dissipator take the lead in starting to work, Larger damping is generated, a large amount of earthquakes for consuming input structure or wind shake energy turn the energy such as kinetic energy or the elastic potential energy of structure The forms such as chemical conversion thermal energy dissipate, and the earthquake of rapid attenuating structure or Wind Vibration Response (displacement, speed, acceleration etc.) make to lead Body structure avoids the occurrence of apparent inelastic state, protects main structure and component in macroseism or strong wind from destroying.Because The reasons such as earthquake are transferred to the external energy of building structure, are the roots that structure generates vibration, so setting energy consumption in the structure Device increases energy consumption, it will reduce the dynamic respons of structure.The constraint coagulation of the anti-buckling energy-consumption component researched and developed at present Soil is easily crushed and loses constraint and anti-buckling effect, its energy dissipation capacity is caused to be greatly reduced.Therefore, some dissipative members Manufacturing process, there is still a need for further improvements for energy-dissipating property etc..
