Pall friction damper
Webof Pall friction-dampers is independent of temperature and velocity. For a given force and displacement in a damper, the energy dissipation of Pall friction-damper is the largest compared to other damping devices (Figure 4). Therefore, fewer Pall friction-dampers are required to provide a given amount of supplemental damping. WebApr 18, 2024 · Pall Friction Dampers have been used for the seismic protection of more than 80 major building projects, including the Boeing Commercial Airplane Factory at Everett, WA the worlds largest building in volume.This offered savings of more than 50% over conventional retrofit scheme.
