Description
Technical field
The present invention relates to a kind of building and bridge structure shock isolating pedestal, more particularly, to a kind of benzvalene form sliding friction-roller bearing rolling
Dynamic friction combined isolation bearing.
Background technology
Earthquake is one of common disaster of the earth, often results in building and the collapsing, to economic and social of bridge structure thing
Development brings great impact.The rigidity that simple dependence improves works is not only uneconomical to resist earthquake disaster, and also has
Seismic force may be increased, can not really play the purpose of antidetonation.Shock insulation skill is introduced in building and bridge structure Aseismic Design
Art, can make earthquake isolating equipment on the premise of meeting normal usage function requirement, reach the extending structure cycle, consume seismic energy
Amount, the purpose of reduction structural response.
