Axial　compression　tests　of　17　CFRP-PE-stainless　steel-reinforced　concrete　（CPSSRC）　short　columns　and　8　counterparts　were　carried　out　to　investigate　the　influences　of　the　stainless　steel　type，hoop　spacing，CFRP　thickness，and　PE　thickness　on　the　failure　mode，load　versus　strain　curve，ultimate　strain，ultimate　strength　and　ductility　of　the　CPSSRC　short　column.　The　experimental　results　showed　that　the　PE　cushion　between　CFRP　and　concrete　improved　the　ductility　of　the　CPSSRC　column　and　reduced　its　ultimate　strength.　Increasing　the　CFRP　thickness　improved　the　ultimate　strength　and　ultimate　strain　of　the　CPSSRC　short　column，but　increased　the　brittleness.　Reducing　hoop　spacing　or　increasing　steel　strength　improved　the　ultimate　strength，peak　strain，and　ductility　of　the　column.　A　finite　element（FE）model　was　established.　The　FE　analysis　showed　that　increasing　the　thickness-to-diameter　ratio　of　the　PE　cushion　significantly　improved　the　deformation　capacity　and　ductility　of　the　CPSSRC　short　column　and　reduced　the　effect　of　CFRP　on　its　ultimate　strength.　Increasing　the　hoop　ratio，stainless　steel　strength，CFRP　tensile　strength，and　CFRP　thickness　improved　the　ultimate　strain　and　ultimate　strength　of　the　CPSSRC　short　column.　Increasing　the　concrete　strength　improved　the　ultimate　strength　of　the　CPSSRC　short　column　but　reduced　its　ultimate　strain.　Finally，a　ductile　design　method，ultimate　strength　model，and　ultimate　strain　model　for　the　CPSSRC　short　column　were　proposed.　©　2024　Hunan　University.　All　rights　reserved.
