Base isolation (device). A device used to isolate structures from earthquake motions.

Beam. Horizontal structural element that usually supports the floor or roof slab system.

Bracing element. Structural element that provides lateral support to increase stiffness and reduce deformations, while strengthening the structure.

Column. Vertical structural element that supports the attached beams while transferring loads to foundation.

Confinement. Containment of compression concrete in a properly designed steel cage of a structural element for improved strength and inelastic deformability.

Damping. Any effect that gradually reduces vibration amplitude or motion.

Damper. A device that introduces damping.

Drift. Horizontal displacement of a building, storey level, or vertical element divided by the respective height.

Ductility. Ability to deform in the inelastic range of deformations without a significant loss of strength.

Energy dissipation (device or mechanism). A device or...
