To　study　the　cyclic　behavior　of　partially　precast　steel　fiber　high-strength　concrete　columns　with　high-strength　steel　bars,　four　full-sized　square　column　specimens　were　fabricated　and　tested　under　constant　axial　load　and　horizontal　cyclic　load.　The　effects　of　the　strength　of　precast　concrete　shell　and　the　diameter　of　cast-in-place　column　core　were　analyzed　in　detail.　The　results　show　that　partially　precast　steel　fiber　high-strength　concrete　columns　have　good　seismic　performance　and　deformation　ability.　Compared　to　the　concrete　column　with　lower　strength　of　precast　concrete　shell,　the　concrete　column　with　higher　strength　of　precast　concrete　shell　showed　higher　bearing　capacity　and　energy　dissipation　capacity　while　lower　ductility.　Moreover,　with　the　increase　of　the　diameter　of　cast-in-place　column　core,　the　bearing　capacity　and　the　deformation　ability　of　the　specimen　decreased.　Finally,　based　on　the　experimental　research　and　theoretical　analysis,　a　calculation　model　for　predicting　the　maximum　bearing　capacity　was　proposed,　and　the　results　obtained　from　the　formulas　were　in　good　agreement　with　those　from　the　experiments.
