In　order　to　study　the　main　effected　factors　of　the　aseismic　performance　of　concrete　dampers,　experiment　of　dampers　in　forms　of　concrete　ductile　columns　was　conducted　to　be　subjected　to　low　cyclic　loading,　The　damage　pattern,　hysteresis　behavior,　ductility　factor　and　equivalent　viscous　damper　factor　of　the　dampers　were　obtained.　The　analysis　showed　that　the　dampers　of　ductle　column　possessed　good　aseismic　performance.
