What are the different types of earthquake dampers?
Dampers:- Dampers are the devices which are used to absorb or dissipate the vibration caused by the earthquake to the structure and to increase the damping and stiffness of the structure. Types of dampers:- 1. Tuned mass damper (TMDs). 2. Tuned liquid mass damper (TLDs). 3. Friction damper. 4. Metallic damper. 5. Viscous damper. 6.
What are the different types of friction dampers?
Friction Damper A friction damper is a device which are used in the structure to dissipate the vibration caused by earthquake hazards. In this damper there are steel plates which are fixed with high strength bolts. 7. Metallic Damper The metallic damper are the devices which are constructed with mild steel plates.
Which is better viscoelastic damper or viscous damper?
According to the obtained results, the viscous damper reduce the results upto 40% to 50% but about viscoelastic damper it allows to reduce only 15% to 25% for all parameters. Hence is concluded that adding dampers to the structure will definitely reduce the seismic response of the structure.
