To　study　the　seismic　behavior　of　specially　shaped　concrete-filled　tube　(CFT)　columns　with　multiple　cavities　under　axial　tension　or　axial　compression,　a　quasistatic　test　of　four　1/30-scale　specially　shaped　CFT　columns　with　multiple　cavities　was　conducted　based　on　the　CFT　mega　columns　in　a　super-high-rise　building.　The　main　parameters　of　the　4　specimens　were　the　direction　of　axial　force,　the　direction　of　horizontal　force,　and　the　cross-sectional　structural　form.　The　test　was　conducted　twice　at　each　level　of　horizontal　displacement.　The　results　shows　that　the　compression-flexure　test　specimen　showed　lower　yield　damage,　higher　bearing　capacity,　and　superior　seismic　performance　relative　to　the　tension-flexure　test　specimen;　the　specimen　loaded　along　the　short　axis　of　the　section　had　a　lower　bearing　capacity　and　stiffness　relative　to　the　specimen　loaded　along　the　long　axis;　and　the　corner-reinforced　specimen　with　a　round　steel　pipe　was　found　to　be　rationally　designed　and　properly　constructed.　Finally,　an　N-M　correlation　curve　was　generated　and　found　to　show　satisfactory　agreement　between　the　fitted　values　and　the　test　values.
