Seismic base isolation with fretted bearings is an appropriate solution for most structures in zones with a moderate level of seismicity, like most regions of Quebec. However, the inherent damping rate in fretted bearings is very limited (around 5%). Therefore, this research project aims to study different methods to improve the damping rate of the fretted bearings in an efficient, economical, and environmentally safe manner.
