To　achieve　highly　durable　resilient　structures,　a　novel　composite　column　was　devised.　This　column　utilized　steel-FRP　composite　bar　(SFCB)　as　an　alternative　to　steel　reinforcement,　along　with　the　incorporation　of　engineered　cementitious　composites　(ECC)　instead　of　normal　concrete　within　the　plastic　hinge　region.　Quasi-static　tests　of　SFCB-ECC-concrete　composite　columns　were　conducted　under　an　axial　load　ratio　of　0.13.　The　influence　of　FRP　content　in　SFCB　(0%,　43.6%,　100%)　and　the　matrix　type　in　the　plastic　hinge　region　(ECC,　concrete)　on　the　seismic　behavior　and　resilience　of　the　composite　columns　was　assessed.　Subsequently,　parameter　analyses　were　conducted　through　OpenSees,　exploring　the　effect　of　axial　load　ratios,　SFCB　reinforcement　ratios　and　ECC　strengths.　The　research　showed　that　the　utilization　of　SFCB　endowed　the　specimen　with　post-yield　stiffness　property,　facilitating　the　swift　restoration　of　its　original　functionalities　without　repair　until　a　2%　drift　ratio.　The　residual　deformation　of　the　composite　column　decreased　with　the　increasing　FRP　content　in　SFCB,　but　its　initial　stiffness　and　peak　bearing　capacity　correspondingly　declined.　Substituting　ECC　for　normal　concrete　in　the　plastic　hinge　region　can　further　mitigate　residual　deformation,　coupled　with　a　remarkable　increase　in　both　peak　bearing　capacity　and　ductility.　The　parameter　analyses　revealed　that　increasing　the　axial　load　ratio　enhanced　the　bearing　capacity　of　the　SFCB-ECC-concrete　composite　column,　but　reduced　ductility.　Moreover,　as　the　reinforcement　ratio　of　SFCB　and　the　strength　of　ECC　increased,　the　bearing　capacity　and　ductility　correspondingly　were　amplified.　In　practical　engineering　applications,　it　is　possible　to　rationally　design　the　material　properties　of　SFCB　and　ECC　to　meet　the　specific　requirements　for　structural　stiffness,　strength,　and　reparability.　©　2025　Harbin　Institute　of　Technology.　All　rights　reserved.
