Based on finite element formulation, it is revealed that the natural period, the capacity of the bearing displacement and damping effect for a Direction Optimized-Friction Pendulum System (DO-FPS) change continually during earthquakes. Therefore, DO-FPS can avoid possibility of resonance of enriched frequencies from ground motions and provide an effective capacity of bearing displacement and damping during the earthquakes. Simultaneously, results from the shaking table tests also illustrate that the DO-FPS isolator possesses an outstanding seismic mitigation capabilities.
