Successively amplify.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；Even if agent structure is not destroyed but the breaking-up of architectural coating, finishing or other non-structural accessories etc.
It can lead to heavy losses；The destruction of indoor costliness instrument, equipment can lead to serious loss or secondary disaster.In order to avoid above-mentioned
The generation of 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 certain nonload bearing elements (such as shear wall, connector) of structure are designed to energy dissipating rod piece,
Or energy-consuming device is installed at certain positions (interlayer space, node, connecting sewing etc.) of structure.In small wind or small shake, this
There is enough lateral rigidities to meet requirement for a little energy dissipating rod pieces (or energy dissipator) and structure itself, and structure is to be in bullet
Character state；When there is big shake or strong wind, with the increase of structure lateral deformation, energy-consuming device takes the lead in starting to work, and generates
Larger damping, a large amount of earthquakes for consuming input structure or wind shake energy, make the energy such as kinetic energy or the elastic potential energy of structure be converted to
The forms such as thermal energy dissipate, and are reduced rapidly earthquake or the Wind Vibration Response (displacement, speed, acceleration etc.) of structure, make main body knot
Structure avoids the occurrence of apparent inelastic state, protects agent structure and component in macroseism or strong wind from destroying.Because of earthquake
Etc. reasons be transferred to the external energy of building structure, be the root that structure generates vibration, so energy-consuming device is arranged in the structure,
Increase energy consumption, it will reduce the dynamic respons of structure.The energy-consuming device researched and developed at present is easily crushed and loses energy consumption
Effect, causes its energy dissipation capacity to be greatly reduced.Therefore, some energy-consuming device manufacturing process, there is still a need for further for energy-dissipating property etc.
It improves.
