Structural Bearings are devices that permit rotation between two structural elements and transmit the required loads in such a way as to prevent any movement (fixed bearings), or allow movement in only one direction (guided bearings), or in all directions of a plane (free bearings).
Seismic protection of building can be done on existing building or in new construction building. The seismic protection can be done by using specific antiseismic devices or dissipative devices.
