Isolation for Earthquake Resistance
The idea that a building can be protected from the damaging effects of an earthquake by using some type of support that uncouples it from the ground is an appealing one, and many mechanisms to produce this result have been proposed during the last hundred years. Many of these utilized rollers or layers of sand or similar materials that would allow a building to slide. Some examples of these have been built. A building in Savastopol, Ukraine and a five-storey school in Mexico have been built on rollers and there is at least one building in China with a sand layer between the foundation and the building, specifically intended to let it slide in an earthquake.
