In addition to the isolation mechanical properties of seismic isolation rubber bearings to meet the seismic design and use requirements, it also has the following advantages:
In addition, it has sufficient vertical bearing capacity to ensure stable support of the building. The isolation layer in the isolation rubber support structure With a stable elastic reset function, it can automatically reset instantaneously in multiple earthquakes. This is completely incomparable with the friction and slip isolation system.
High damping rubber bearing (HDR)
Its life can reach 80 to 100 years. Seismic mechanical properties will not change significantly, which means that it will not affect the use within 80 years. It can be seen that it has the same life as the building.
Compared with traditional seismic structures, the seismic response of the superstructure is reduced to about 1/4 to 1/8 of the former, and the safety and reliability are greatly improved. , The fortification target of a building can generally be increased by one fortification level; the traditional fortification target is "small earthquakes are not bad, repairs can be made in mid-earthquakes, and large earthquakes cannot fall down", while isolated buildings can achieve "small shocks are not bad, and moderate Bad or mildly not bad, the major earthquake does not lose the function of use," its potential economic and social benefits are very considerable. If we add up the losses caused by the destruction of the building structure, the loss of internal property, the casualties and the work stoppage caused by the destruction of the building during the earthquake. The economic and social benefits of this isolation system are huge.
