The　application　of　the　Friction　Pendulum　System　(FPS)　to　seismic　isolation　of　lattice　shell　structures　has　been　presented　in　this　paper.　Theoretical　model　of　the　FPS　is　first　introduced.　Equation　of　motions　of　lattice　shell　with　FPS　bearings　is　established.　Then,　seismic　isolation　studies　are　performed　for　double-layer　spherical　lattice　shell　structures　subjected　to　three-component　seismic　excitations.　Meantime,　seismic　isolation　performance　of　the　FPS　is　investigated　under　different　earthquake　inputs.　The　results　show　that　this　type　of　isolation　bearing　provides　excellent　property　of　seismic　isolation　and　energy　dissipation.　Therefore,　it　is　indicated　that　the　FPS　bearing　can　be　effectively　utilized　to　vibration　control　of　spherical　lattice　structures.　©　2011　IEEE.
