Two　1:8　scale　specimens　were　designed　and　created　to　examine　the　seismic　performance　of　concrete-filled　steel　tubular　(CFST)　composite　columns　with　ultra　high　performance　concrete　(UHPC)　plates.　Ground　motion　characteristics,　axial　pressure　ratio,　plate　material,　and　mainshock-aftershock　sequences　were　used　as　parameters　in　the　pseudo-dynamic　test　study.　The　results　show　that　the　ground　motion　characteristics　have　a　significant　effect　on　the　seismic　response　of　the　specimen;　The　initial　stiffness　of　the　specimens　is　mostly　unaffected　by　the　axial　pressure　ratio.　Furthermore,　the　larger　the　axial　pressure　ratio,　the　earlier　the　specimen　enters　yielding　and　the　more　severe　the　final　failure　phenomenon;　After　UHPC　was　used　in　place　of　the　plate　material,　the　specimen＇s　initial　stiffness　rose　by　about　13.7%,　the　stiffness　degradation　of　the　specimen　was　somewhat　delayed,　and　the　hysteretic　energy　dissipation　increased　by　about　41.2%.;　The　specimen　undergoes　elastic,　elastoplastic,　and　plastic　failure　stages　under　the　aftershocks　of　increasing　intensity.　Under　the　mainshock-aftershock　sequences　of　the　same　intensity,　the　seismic　response　of　the　specimens　under　the　aftershock　was　not　much　different　compared　to　the　mainshock,　and　the　hysteretic　energy　dissipation　was　about　67.7%　and　74.5%　of　the　mainshock　respectively.　These　structures　can　withstand　multiple　earthquakes　and　have　demonstrated　good　seismic　performance.　©　2022　Elsevier　Ltd
