Abstract

The friction pendulum type seismic isolation system (FPS) using the PTFE based materials has been developed to provide a simple and effective way to achieve earthquake resistance for buildings. PTFE matrials are soft and apt to be deformed easily after a few working cycles. Instead of the usual PTFE materials, the Polyimide material was used in this research. Polyimide is harder than PTFE, but has smaller friction coefficient and longer duration fur usage. In this paper, various kinds of PTFE materials were tested to define the frictional characteristics compared with the Polyimide material. FPS was manufactured with fine surface roughness and used with Polyimide material to show the seismic isolation efficiency, and life duration when applied to a rigid mass model and a 5 stole frame model.
