Description

A kind of band recovers the seismic isolation and reduction structure and its design method of function
Technical field
The present invention relates to the seismic isolation and reduction structure and its design method that a kind of band recovers function, belong to building structure field.
Background technology
With the building of friction-pendulum shock-insulation support under the small shake effect of suitable earthquake intensity, it is impossible to its function of shock insulation is played, in Shake and the lower isolating affection of big shake effect are obvious, and have the characteristic of friction energy-dissipating and Self-resetting.The extensional rigidity of friction pendulum support is near It is zero, for the Lateral Force such as seismic force when skyscraper, certain pulling force will occurs in Architectural fringes and corner, therefore right It is arranged in building periphery(Particularly skyscraper periphery)Friction pendulum support easily there is situation about pulling.
Seismic energy dissipation structure provides additional resistance mainly by increasing energy dissipation component or damper in the structure, for structural system Buddhist nun.By energy dissipation component or damper to earthquake dissipation of energy, reach the purpose for protecting primary structural member.But shaking greatly Even super rarely occurred earthquake when, dissipative member or damper are not enough to consume more seismic energy, and most seismic energies is also It is to be consumed by agent structure component.Therefore, in big shake and super rarely occurred earthquake, the body structure portion of seismic energy dissipation structure is still Damage so is had, the deformation of its agent structure and damage are difficult to repair.
NEES/E-Defence America and Japan engineering second stage joint study meeting of the functional structure original in America and Japan scholar can be recovered View.Its main thought is the recovery of malformation and damage.Current Main is:Waving shear wall and rocking frame Malformation can recover after upper application prestressing force reaches shake;Damaged member by changing structure reaches the recovery of structural damage. But in large scale structure, wave wall and rocking frame applies prestressing force difficulty, and loss of prestress is uncontrollable.
The content of the invention
In view of the shortcomings of the prior art, the invention provides seismic isolation and reduction structure and its design side that a kind of band recovers function Method.
