Abstract: FPS is applied to a single-layer spherical lattice shell to investigate its seismic isolation performance.The governing equations for the structure with FPS are developed.It adopts time history to analyze single-layer spherical lattice shell which is used usually in engineering.By changing the intensity of earthquake motion firstly,the influence of friction coefficient and slide-way radius of FPS on displacement of the seismic isolation floor and nodal acceleration is analyzed comprehensively. The variation rule of seismic responses with the variation of friction coefficient and slide-way radius of FPS is summarized. And the results can provide references for selecting parameters of FPS in lattice shells.
