This　article　experimentally　investigates　the　cyclic　behavior　of　ultra　high　performance　concrete–filled　steel　tube　beam-columns.　A　total　of　eight　specimens　were　tested.　The　considered　parameters　were　the　axial　load　ratio　and　steel　ratio.　The　results　showed　that　all　ultra　high　performance　concrete–filled　steel　tube　beam-columns　had　a　very　good　cyclic　behavior　without　significant　pinching.　Increasing　the　axial　load　ratio　results　in　the　decrease　of　strength　and　ductility,　but　it　has　no　obvious　influence　on　the　initial　flexural　stiffness.　Reducing　the　steel　ratio　results　in　the　decrease　of　the　strength,　stiffness　and　ductility,　and　energy　dissipation　capacity.　©　The　Author(s)　2019.
