To　solve　the　problem　of　validity　and　calculation　method　of　a　new　type　of　composite　isolation　bearing　with　friction　damper,　this　paper　studied　the　finite　element　method　(FEM)　calculation　model　of　composite　elements　for　structural　design,　including　horizontal　and　vertical　stiffness　and　hysteretic　model.　Using　the　finite　element　software　SAP2000,　and　comparing　the　optimized　isolation　scheme　with　the　traditional　rubber　bearing,　the　seismic　performance　of　high-rise　frame-shear　wall　tube　structures　with　different　aspect　ratios　was　studied.　Results　show　that　compared　with　the　traditional　isolation　bearing　scheme,　the　combined　isolation　bearing　scheme　can　appropriately　prolong　the　natural　vibration　period　of　the　structure,　reduce　the　lateral　displacement　of　the　isolation　layer,　effectively　reduce　the　tensile　stress　of　the　bearing,　and　improve　the　overturning　resistance　and　energy　consumption　of　the　bearing.　It　can　also　effectively　reduce　the　seismic　response　of　the　superstructure,　such　as　interlayer　shear　force　and　lateral　displacement,　which　proves　that　the　comprehensive　effect　of　the　combined　isolation　bearing　scheme　is　obvious　compared　with　that　of　the　traditional　isolation　bearing　scheme.　©　2024　Beijing　University　of　Technology.　All　rights　reserved.
