In　order　to　research　the　dynamic　properties　of　the　strengthening　RC　short　columns　with　prestrssed　steel　wires(PSW),　seven　RC　columns　were　tested　under　cyclic　load　and　constant　axial.　Under　low　frequency　cyclic　loading,　test　phenomena　were　described.　Experimental　data　are　analyzed　and　compared,　and　the　effects　of　configuration　index　of　PSW,　prestressing　level　of　PSW　and　axial　compression　ratio　on　the　seismic　behavior　are　studied.　The　results　show　that　the　seismic　performance　of　the　retrofitted　specimens　could　be　effectively　enhanced,　ductility　and　energy　dissipation　are　improved　significantly.　The　biggest　displacement　ductility　factor　and　accumulated　energy　dissipation　of　the　columns　strengthened　with　PSW　are　1.87　times　and　6.78　times　higher　respectively　than　that　of　the　un-strengthened　column.　The　seismic　performance　of　the　retrofitted　columns　can　be　improved　significantly　by　increasing　the　configuration　index　and/or　the　prestressed　level　of　PSW.　If　the　configuration　index　of　PSW　is　bigger　than　0.119,　the　prestressed　level　reaches　0.40,　the　seismic　performance　of　the　retrofitted　specimens　can　be　improved　effectively　when　the　axial　load　ratio　is　lower　than　0.3.　Based　the　test　results,　the　calculating　formulas　of　the　shear　capacity　of　RC　short　columns　strengthened　with　PSW　were　proposed,　which　may　be　useful　for　engineering　design　and　further　study.
