Research about Efficiency for Double Slipping-Surfaced FPS Seismic Isolating System

Article Preview

Abstract:

Numerical analyzing approach about a novel seismic isolation system, DFPS (Double Slippingsurfaced Friction Plate System), is presented in this paper. It starts from Lagrange equation, its governing equation is similar to that of the FPS friction pendulum system with single slipping surface. Result shows that storey drift resulted from seismic action tend to be even along the height, and interstorey drift, storey velocity and acceleration are significantly decreased on buildings equipped with DFPS system. An optimistic combination of them could exhibit good seismic isolation efficiency. It could reach 70% for μ=0.05, r=3.5m.
