ABSTRACT
The friction pendulum system is a passive earthquake device used for a seismic isolation of buildings, bridges and other types of structures; their purpose is to protect, control and limit the energy transfer from the soil to the structure and fully dissipate seismic energy. In the paper we determine the stiffness and effective period of the friction pendulum system with one sliding surface for different levels of horizontal load.
