The　application　of　friction　pendulum　system　(FPS)　to　seismic　isolation　of　lattice　shell　structures　is　presented.　Theoretical　model　of　the　FPS　is　first　introduced.　Motion　equations　of　the　lattice　shell　with　FPS　bearings　are　established.　Then,　seismic　isolation　studies　are　performed　for　double-layer　spherical　lattice　shell　structures　subjected　to　both　single　and　three-component　seismic　excitations.　Meantime,　seismic　isolation　performance　of　the　FPS　is　investigated　under　different　earthquake　inputs.　The　results　show　that　the　isolation　bearins　provide　the　excellent　properties　of　seismic　isolation　and　energy　dissipation.　Therefore,　the　FPS　can　be　effectively　utilized　to　control　the　seismic　response　of　the　spherical　lattice　shell　structures.
