Self Centring Friction Dampers
1. Dampers are designed to withstand earthquakes and aftershocks without repair or replacement (to specified capacity).
2. As opposed to traditional yielding anchorage systems, damper capacity degradation and residual deformations are not expected during and after earthquakes.
3. With exceptional added earthquake dampening through friction, any range of R factors is achievable for new tanks.
4. For existing tanks/silos, the R factor can be significantly improved by replacing the existing anchors.
5. Dampers can be installed on new or existing tanks.
6. Existing tanks can be retrofitted with minimum business interruption and without shortening or strengthening of tank wall/barrel.
7. Each damper is performance tested to ensure it performs to its required specification.
8. Cost saving in steel tank thickness and concrete foundation slab thickness and reinforcement due to reduced earthquake forces when SCFD is implemented.
