In　order　to　realize　the　seismic　behavior　of　concrete　filled　CHS　(circular　hollow　section)　and　SHS　(square　hollow　section)　columns　and　steel　beam　planar　frames,　twelve　test　specimens　were　experimentally　studied　under　constant　axial　load　and　cyclically　lateral　load.　The　column　shape　(CHS　and　SHS),　steel　ratio　of　the　column　section　(CHS:　＇　=　0.06,　0.103;　SHS:　＇　=　0.125,　0.126),　axial　load　level　of　column(CHS:　n　=　0.06-0.60;　SHS:　n　=　0.04-0.60),　linear　stiffness　ratio　of　steel　beam＇s　to　column＇s　(CHS:　i　=　0.36-0.58;　SHS:　i　=　0.34-0.62),　are　all　considered　as　experimental　parameters.　The　test　results　show　that　the　lateral　load　(P)　versus　lateral　displacement　hysteretic　curves　of　the　frames　are　plump　shuttle　shape.　The　curves　have　no　obvious　strength　and　stiffness　degradation.　The　axial　load　level　of　columns　and　steel　ratio　of　the　section　have　an　evident　effect　on　the　strength　and　seismic　behavior　of　the　frames,　and　with　the　increase　of　axial　load　level　of　columns,　the　lateral　ultimate　strength　of　the　frames　becomes　low,　and　the　ductility　of　displacement　and　the　capacity　of　energy　dissipation　also　become　descending,　but　the　steel　ratio　has　the　opposite　results.　The　frames　with　concrete　filled　CHS　columns　have　a　better　seismic　behavior　than　the　frames　with　concrete　filled　SHS　columns.　All　the　test　frames　which　are　designed　by　the　specification　DBJ　13-51-2003　can　meet　the　requirements　of　seismic　design.
