Description
Technical field
The present invention relates to ambient vibration and antidetonation, cushion technique field, be specifically related to a kind of vertical earthquake isolating equipment, in common building thing, special construction, bridge and plant equipment damping/shake.
Background technology
Violent earthquake is one of serious natural calamity threatening the mankind.Seismic isolation structure system increases structural damping by the natural vibration period extending superstructure, reduces the earthquake response of structure, guarantees that superstructure still can be in elastic stage when violent earthquake, or remain on the A-stage of elastic-plastic deformation.Seismic isolation technology not only ensure that the safety of structure itself, also protects inside configuration equipment, facility.But during horizontal seismic isolation design, scholars generally payes attention to horizontal earthquake action, ignores Vertical Earthquake Loads, the isolated component generally used at present can only level of isolation earthquake, does not have isolation effect for vertical seismic action.And can vertical seismic responses be amplified.Therefore in the highlight lines area that Vertical Earthquake Loads is larger, although horizontal earthquake action can reduce greatly after adopting seismic isolation technology, Vertical Earthquake Loads likely becomes the major control factors of structural response and causes degree of safety to reduce.
Earthquake disaster macroscopic appearance shows, also clearly, its value is also very considerable in the impact of Vertical Earthquake Loads.Vertical Seismic Action of Structures causes primarily of P wave, and the general comparatively shear wave of vertical velocity of wave propagation is fast, thus the center people that occur of earthquake feel it is first pitch, rear double swerve.In seismic center district, first building suffers vertical earthquake, then bears horizontal earthquake action, and during earthquake vertical component general all prior to level to reaching its maximum value.In high intensity Zone (especially epicentral area), earthquake disaster phenomenon shows, the vertical component of acceleration of earthquake motion is obvious on the collapse state of building and the impact of destructiveness.Seismic monitoring shows, there is the seismographic record that vertical seismic action peak accelerator meets or exceeds acceleration peak.From strong-motion earthquake observation data, the vertical component of strong earthquake motion has more radio-frequency component than horizontal component.In the last few years, the seismographic record that vertical peak accelerator meets or exceeds acceleration peak had been obtained.Therefore vertical seismic action can not be ignored the impact of works, and its effect exceedes horizontal earthquake sometimes, and again because structure vertical rigidity is large, its vertical natural period and vertically seismic wave predominant period are close, and thus the vertical vibrant characteristic of structure receives much concern.
Similar to the damping mechanism of horizontal seismic isolation, in order to reach significantly vertical damping effect, vertical earthquake isolating bearing should have lower vertical rigidity, has higher vertical bearing capacity and vertical damping again, also larger vertical deformation should be able to occur.For the three-dimensional isolation device of isolating earthquake and vibration simultaneously, due to being coupled of level and vertical motion effect, this earthquake isolating equipment is made to become international headache.At present, alleviate horizontal and vertical seismic loads had a lot of trials for by inventing a uncertain three-dimensional shock isolation support.A lot of three-dimensional isolation device all has good vertical earthquake isolating performance or damping capacity, but the shortcoming of these equipment can not be ignored, because they are very expensive, and shape matching is large comparatively speaking, thus limits the possibility of its large-scale production.
