WebFriction pendulum bearing (FPB) shows superior performance in reducing dynamic responses of structures under earthquakes. Though the seismic response of the FPB-isolated structure is well understood, its overturning resistance caused by limited permissible displacement under impact is rarely studied. WebFriction Pendulum™ isolators use the characteristics of a pendulum to lengthen the natural period of the isolated structure so as to avoid the strongest earthquake forces. During an earthquake, the supported structure moves with small pendulum motions.
