To　study　the　cyclic　behavior　of　steel　tube-reinforced,　high-strength　concrete　columns　with　high-strength　steel　bars,　a　cyclic　loading　test　of　six　full-sized　square　columns　was　carried　out,　including　one　traditional　reinforced　concrete　(RC)　column　and　five　steel　tube-reinforced　concrete　(STRC)　composite　columns.　The　cross-sectional　shape　of　the　inner　steel　tube,　the　strength　matching　of　the　outer　concrete　and　the　core　concrete,　and　the　presence　of　steel　fiber　in　outer　concrete　were　the　major　parameters　of　the　test.　The　research　shows　that　steel　fiber-reinforced　high-strength　STRC　composite　columns　had　better　seismic　behavior　compared　to　RC　columns.　The　strength　matching　method,　where　the　C90　core　concrete　was　combined　with　the　C70　outer　concrete,　resulted　in　a　better　composite　effect　in　comparison　to　the　method　of　using　C80　concrete　in　both　core　concrete　and　outer　concrete.　Moreover,　the　addition　of　steel　fibers　in　outer　concrete　effectively　reduced　the　damage　degree　and　improved　the　ductility,　resilient　capacity,　and　energy　dissipation　capacity　of　the　specimens.　Finally,　based　on　the　test　research　and　theoretical　analysis,　a　calculation　model　for　predicting　the　maximum　load-carrying　capacity　was　proposed.　The　model　was　then　verified　by　comparing　its　predictions　with　test　results.
