Description
Technical field
Construction Anti-earthquake technical field is the utility model is related to, more particularly to a kind of rocking from vibration-proof structure.
Background technology
Two approach are substantially undergone in the development of house architectural structure Aseismic Design technology, i.e., from improving structure itself resistance
Shake ability is set out, development high performance material, component and structural system etc.；Or structural earthquake exciter response is reduced by vibration control.
With by earthquake control in desired extent, reach structural seismic fortification, make structure meet with earthquake when do not occur destroy or only
Generation can repair damage rapidly.The control of structural earthquake exciter response has passive energy dissipation or vibration isolation approach again, disappears as set up in structure
Energy damper sets up basic vibration insulation isolation geological process etc..Passive energy dissipation and vibration isolation in practice might not river rising in Ningxia and flowing into central Shaanxi Weihe point
Bright, the vibration control in engineering often contains the two concepts simultaneously.
A kind of some privileged sites of specific aim loosening configuration component constraint weakening structure of prior art appearance are with control structure
Vibration, such as natural rubber bearing vibration insulating foundation structure, framework-wave core wall structure.Now, structure or part thereof is often presented
The vibration of approximate rigid body mode is included, first natural frequency of vibration reduces by a relatively large margin, and rigid body mode may be rendered as translating or turn again
It is dynamic, but it is swinging structure to be referred to as this class formation.Further, dissipative cell can be set up at structural weakening position, puts into practice vibration isolation and consumption
Energy vibration damping use in conjunction, while be advantageous to reduce weakened location seismic deformation；Or apply soap-free emulsion polymeization post-tensioning at structural weakening position
Draw prestressing force, further can enhancing structure stability, and make structure that there is certain self-resetting capability when seismic deformation is larger.
Compare with traditional structure, swinging structure can typically reduce energy input of the earthquake to structure by a relatively large margin, have certainly
Vibration damping or self-resetting capability etc.；But the rigidity weakened location seismic deformation of swinging structure is larger, and usually contains structure or non-knot
Structure annex, or using application prestressing without bondn etc., it is necessary to more meticulous design, construction and maintenance.
