Damper systems are designed and manufactured to protect structural integrities, control structural damages, and to prevent injuries to the residents by absorbing seismic energy and reducing deformations in the structure. There are several types of seismic dampers namely viscous damper, friction damper, yielding damper, magnetic damper, and tuned mass damper.
1. Viscous Dampers
Viscous dampers are used in high-rise buildings in seismic areas. It can operate over an ambient temperature ranging from 40°C to 70°C.
2. Viscoelastic Dampers
This type of damper dissipates the building’s mechanical energy by converting it into heat.
3. Friction Dampers
A friction damper device consists of several steel plates sliding against each other in opposite directions.
4. Tuned Mass Damper (TMD)
Tuned Mass Damper (TMD), also known as vibration absorbers or vibration dampers, is a passive control device mounted to a specific location in a structure
5. Yielding Dampers
Yielding damper or metallic yielding energy dissipation device or passive energy dissipation device is manufactured from easily yielded metal or alloy material.
