Description
Technical field
The present invention relates to a kind of building and bridge construction shock isolating pedestal, particularly relate to a kind of benzvalene form sliding friction-roller bearing rolling friction combined isolation bearing.
Background technology
Earthquake is one of common disaster of the earth, usually causes building and the collapsing of bridge construction thing, brings great impact to economy and social development.It is not only uneconomical that the rigidity that simple dependence improves works resists earthquake disaster, but also likely increase seismic forces, really can not play the object of antidetonation.In building and bridge construction seismic design, introduce seismic isolation technology, can make earthquake isolating equipment under the prerequisite meeting normal usage function requirement, reach the object of extending structure cycle, earthquake energy, reduction structural response.
When earthquake occurs, in order to ensure that the wounded are rescued timely and treat, hospital architecture can not be collapsed; In order to ensure that disaster relief personnel and goods and materials enter into disaster area, the lifeline engineering such as bridge must ensure safe and smooth.When said structure thing is designed and constructed, appropriate design and installation earthquake isolating equipment can well avoid it under geological process, collapse to occur.
Along with the development of building structure seismic isolation technology, current a lot of earthquake-prone countries and area in the world, when building and bridge construction is newly-built, shock isolating pedestal is installed, by reliable earthquake isolating equipment reasonable in design, it is made to play a significant role in structural seismic, make the most power consumption of works and concentration of plastic deformation in these earthquake isolating equipments, allow earthquake isolating equipment larger plastic strain occurs under rarely occurred earthquake effect and there is certain permanent set, thus ensure that other structural element is in elasticity or finite plastic domain.
