This　paper　presents　bending　test　results　of　carbon　fiber　reinforced　polymer　(CFRP)　composites　retrofitted　concrete-filled　steel　tubular　(CFST)　beams　after　exposure　to　fire.　Both　circular　and　square　specimens　were　tested　to　investigate　the　retrofitting　effects　of　uni-directional　CFRP　composites　on　them.　The　test　results　showed　that　the　strengthening　effect　for　beams　was　not　so　good　compared　with　their　stub　column　counterparts.　Therefore,　it　is　recommended　that,　in　retrofitting　CFST　beams,　other　appropriate　strengthening　measures　should　be　taken　to　improve　the　performance　of　uni-directional　CFRP　composites　or　bi-directional　CFRP　composites　should　be　applied.
