Rebar　corrosion　is　a　potential　cause　of　punching　shear　failure　in　slab-column　structures.　One　economical　and　effective　solution　is　partially　replacing　traditional　steel　rebars　with　corrosion-resistant　materials　such　as　basalt　fiber　reinforced　polymer　(BFRP)　bars.　This　study　investigates　the　punching　shear　performance　of　slab-column　connections　with　hybrid　bars　through　an　experimental　program　involving　two　reinforced　concrete　(RC)　slab-column　connection　specimens　and　four　specimens　reinforced　by　hybrid　steel　and　BFRP　bars.　The　BFRP　bars　used　were　equivalent　in　either　area　or　stiffness　to　the　replaced　steel　bars.　The　experimental　results　showed　that　partial　replacement　with　BFRP　bars　of　equivalent　area　led　to　decreased　initial　stiffness　and　reduction　in　punching　shear　strength　by　7.9%　to　14.6%,　respectively.　Replacement　based　on　equivalent　stiffness　slightly　increased　the　initial　stiffness　and　load　capacity　but　decreased　the　energy　dissipation　capacity.　The　numerical　study　was　conducted　to　investigate　the　influential　parameters　and　to　obtain　the　optimal　replacement　area.　Finally,　a　method　was　developed　to　compute　the　punching　shear　strength　of　slab-column　connections　adopting　the　equal-area　replacement　scheme　through　modifying　the　critical　shear　crack　theory　(CSCT).　The　predicted　results　by　the　modified　CSCT　agree　well　with　both　experimental　and　numerical　results.　　©　2025　American　Society　of　Civil　Engineers.
