Prefabricated modular anti-seismic buildings

We have two patents filed regarding anti-seismic constraining systems buildings to the ground.

The first patent has already been issued, the second is awaiting approval.

Due to the constraint claimed with the first patent, with respect to the basement, the building can move and turn horizontally in every direction within linear and angular measures greater than those of displacements, that can be caused by earthquakes of the maximum magnitude foreseeable in the place where the building stands.

When an earthquake is occurring, the aseismic building is not shaken by the basement, since the basement and building can reciprocally move and oscillate horizontally in all directions to a limited extent. 

Similarly, during an earthquake, a plane or a bird in flight is not shaken from the ground.

Seismic tremors, on the other hand, make a normal building oscillate and can seriously damage it, particularly at its base (fig. 3).

During an earthquake, the anti-seismic building, constrained to the base, according to the issued patent, does not cause the liquefaction of the soil and therefore does not tilt or sink (fig. 1 and 2). 

This is due to the fact that the weight of the structure, particularly if metallic, of the building with anti-seismic constraints, can be appreciably lower than that of the structures of current buildings, both traditional and anti-seismic.

And above all, it is due to the fact that, during the earthquake, the basement remains integral with the ground and therefore is not shaken with respect to the ground, neither due to seismic shocks nor due to the inertia of the building.
