BracePall Friction Dampers
Energy is absorbed by surfaces with friction between them against each other

Yielding Damper
16
Plastic Deformation (Yielding) of metal absorb significant amount of seismic energy.
But I am sure you don’t want such kind of deformation of the structure after the earthquake.
Even if the structure is not collapsed totally, the building must be demolished for the future safety

The largest damper sphere in the world, consists of
41 circular steel plates of varying diameters, each
125 mm (4.92 in) thick, welded together to form a
5.5 m (18 ft.) diameter sphere.

Seismic Invisibility Cloak• Concentric plastic rings are
installed underground in the
top if three feet if soil.
• Harder layers are further
from the building. Each time
the wave hits a softer layer it
is deflected off its initial
path.
• Once past the building the
wave can continue on their
path.

Test of Seismic Invisibility Cloaks
Alluvial basin in southern France
• The French team created its so-called metamaterial by drilling three lines of empty boreholes 5 metres
deep in a basin of silted clay up to 200 metres deep.
• They strongly reflect the seismic waves. But one problem with this kind of array is that the reflected waves
could end up doing more damage to buildings nearby
