In　order　to　assess　residual　behavior　of　concrete-filled　steel　tubular　(CFST)　members　after　high　temperature,　especially　residual　bearing　capacity　of　CFST　members　subjected　to　biaxial　force　and　bending,　16　square　CFST　specimens　are　subjected　to　biaxial　eccentric　compression　in　this　paper.　Some　parameters,　i.e.,　cross　section　dimensions,　slenderness　ratio,　eccentricity　and　temperature,　are　discussed　in　emphasis.　On　basis　of　numerical　analysis　and　experimental　results,　a　simplified　formula　is　proposed　to　forecast　residual　bearing　capacity　of　CFST　members　after　high　temperature　subjected　to　biaxial　force　and　bending.　The　analysis　values　are　compared　with　those　of　experimental　and　numerical　analysis　results.　Finally,　a　comparison　of　bearing　capacity　is　made　between　CFST　member　reinforced　with　and　without　carbon-fiber.　The　results　show　that　a　good　agreement　is　in　the　proposed　formula　values　and　experimental　results　as　well　as　numerical　analysis　ones.
