Using the viscoelastic material in the material substitution viscoelasticity laminated member 9 with high-damping, this is as one kind conversion of embodiment.
The present invention is further described below:
Low-carbon steel material has been widely used in vibration damping, and this component mainly realizes elastoplasticity consumption by tension and compression deformation
Can, elastoplasticity yielding stage can be entered when axial force is more than certain numerical value, rigidity substantially reduces, realize similar to spring element
The effect of shock insulation.From grooved perforate steel disc as displacement type antivibrator, in order that it plays geometrical non-linearity function, made
As axially loaded component, in pressurized process, support system flexing unstability to axially loaded component can occur, when extraneous load mistake
Very likely produce damage inactivation when big or uncertain, the reliability of element so cannot be effectively ensured.Flexing unstability is a kind of
The state of element bearing capacity cannot be made full use of, affected by factors such as boundary condition, constraints, component conditions.For reality
The axis tension and compression stress of existing component, can realize component using anti-buckling outer sleeve constraint energy dissipation brace and in tension and be subject to
During pressure, stress core component, because of the constraint of the component that suffers restraints, produces surrender without flexing.By oblique for this component angle
Place, inclined member one end is articulated with base, and one end is articulated with core connection parts, can be symmetrically installed some supports according to function
Component, core connection parts and horizontal seismic isolation bearing adopt bolt-connection, and vertical load passes to core by horizontal seismic isolation bearing
Heart connection parts.
Dissipative member can be added during the deformation of vertical earthquake isolating device, on the one hand reduce vertical seismic action reaction, on the other hand permissible
Control that vertical displacement is excessive causes systematic jitters；And support member adopt displacement type elastoplasticity Energy dissipating material can be at it
After surrender, realize the effect of reciprocal hysteretic energy under vertical tension and compression effect, therefore can effectively realize vertical earthquake isolating and vertical
Power consumption acts on.
Existing three-dimensional shock isolation support is designed as increasing deformability, by expanding facade size, causes height of support higher,
The depth-width ratio of whole bearing is larger, easily causes bearing overall collapse.The present invention mainly by coordinate skewed horizontal load angle Lai
Reach vertical earthquake isolating, therefore highly can obtain ideal numerical value.
Described vertical earthquake isolating control mode is as follows:
Vertical force under action of static load for the vertical earthquake isolating system is as follows:
f1=2f1(u)sinθ+kvu+f2(u)
In formula: u applies produced deformation for static load；f1For channel steel support axially loaded；θ is to support and horizontal folder
Angle；kvFor viscoelasticity laminated member rigidity；f2Damping force for lead for retractable pencil post.
When shock isolation system is under vertical uniform load q, because Seismic Isolation of Isolation Layer vertical rigidity is related to static load displacement, when deformation reaches
To a certain position, support the vertical rigidity providing to be negative stiffness value, be then superimposed with the positive rigidity of vertical viscoelasticity laminated member
Quasi- zero stiffness state can sometime realized, thus realizing vertical earthquake isolating.
If vertical rigidity is more than the absolute value of the negative stiffness numerical value supporting, then vertical earthquake isolating system is under Under Dynamic Load
Vertical force as follows:
f2=kv1x+f2(x)
In formula: x is produced deformation under Under Dynamic Load；kv1For the vertical supporting rigidity under Under Dynamic Load.
