In　this　paper,　a　set　of　test　apparatus　was　first　developed　and　designed　to　load　and　measure　structural　response.　Fourteen　concrete　filled　rectangular　steel　tubular　(CFRST)　columns　subjected　to　biaxial　compression　and　bending,　were　tested　after　high　temperature　exposure.　The　research　emphasized　in　studying　the　effects　of　experimental　parameters,　such　as　temperature,　slenderness　ratio,　eccentric　angle,　height-to-width　ratio　and　confining　coefficient.　The　results　show　that　the　bearing　capacity　and　ductility　are　mainly　influenced　by　the　testing　parameters,　and　types　columns.　After　high　temperature,　the　column　still　had　good　bearing　capacity.　The　average　ductility　factors　of　all　specimens　were　over　8,　this　indicates　that　CFRST　columns　subjected　to　biaxial　compression　and　bending　has　good　ductility　even　after　high　temperature　exposure.
