Earthquake Protector: Shake Table Crash Testing

Comparative earthquake engineering experiments with 12-story building models: the right one is resting on a new type of seismic base isolation called "earthquake protectors", the left one is fixed to the base. The fundamental natural period of superstructures equals 1.2s, the isolated period of Earthquake Protector equals 5.0s, the range of earthquake simulation periods is 0.02 - 2.00s. It is obvious: application of Earthquake Protector can raise a building's seismic sustainability dramatically.
