Blind-bolted　connection　is　a　type　of　new　developed　prefabricated　beam-column　connection,　which　can　be　used　to　connect　the　concrete　filled　steel　tubular　(CFST)　columns　and　the　steel　beams　easily.　The　static　and　dynamic　performance　of　CFST　column　to　steel　beam　joints　with　blind-bolted　connections　have　been　well　explored,　but　limited　research　has　been　conducted　to　investigate　the　fire　and　post-fire　performance　of　this　type　of　composite　joint.　In　this　paper,　a　series　of　reversed　T-shaped　joint　fire　tests　were　conducted　to　investigate　the　fire　and　post-fire　performance　of　blind-bolted　CFST　joints　with　axially　restrained　steel　beams.　The　influence　of　restrained　effect　from　adjacent　members　in　the　entire　frame　structure　on　the　response　of　blind-bolted　joints　in　and　after　fire　could　be　reasonably　considered　by　the　reversed　T-shaped　joint　fire　test.　The　joint　temperature,　failure　modes,　beam　and　column　displacements　and　temperature　internal　force　development　during　the　entire　loading　and　fire　stage　were　recorded　and　discussed.　The　test　results　indicated　that　the　blind-bolted　connections　showed　very　good　working　performance　in　and　after　fire,　and　no　bolt　shank　fracture　or　bolt　pull-out　failure　was　observed.　Finite　element　analysis　(FEA)　models　were　established　to　simulate　the　fire　and　post-fire　performance　of　blind-bolted　CFST　T-shaped　joints　with　axially　restrained　steel　beams,　and　the　joint　moment　versus　relative　rotation　angle　relationship　curves　of　the　blind-bolted　joints　during　the　entire　fire　and　loading　process　were　extracted　and　discussed　based　on　the　FEA　models.　The　results　indicated　that　the　joint　negative　moment　generated　by　the　axially　restrained　beam　boundary　in　the　heating　and　cooling　phases　could　go　up　to　around　1.4　times　the　joint　negative　moment　at　ambient　temperature.　©　2023　Elsevier　Ltd
