Question

What are seismic dampers and why are they important?

Answer 1

A seismic damper is a mechanical device which dissipates kinetic energy of seismic waves penetrating a building structure.

Explanation:

Seismic dampers are used in buildings, bridges or any other constructions to control earthquake induced vibrations on buildings. When seismic waves start to penetrate a base of building structure, seismic dampers can decrease their damaging effect and improve the buildings seismic performance.

These dampers are used in place of structural elements like diagonal braces for controlling seismic damage in structure. It party absorbs the seismic energy and reduces the motion of buildings.
