Abstract. Base isolation is a modern strategy to decrease the effects of earthquakes on buildings of high significance. The general principle is that the structure is decoupled from the horizontal components of the earthquake ground motion by interposing a layer with low lateral stiffness between the structure and the foundation. One of the major devices to apply seismic isolation is Friction Pendulum Systems, which use the characteristics of a pendulum to lengthen the natural period of the…
