The　fire　resistance　of　beam-to-column　connections　affects　the　safety　of　clad　racks　under　fire　conditions.　However,　existing　research　lacks　studies　on　the　behavior　of　these　special　connections　at　high　temperatures.　This　study　investigates　the　fire　resistance　of　clad　rack　beam-to-column　bolted　connections　(CRBCs).　Firstly,　single　cantilever　tests　of　CRBCs　at　temperatures　of　20　°C,　300　°C,　400　°C,　500　°C,　600　°C,　and　700　°C　are　carried　out.　The　failure　modes　of　the　CRBCs　at　600　°C　and　below　are　identical　to　that　at　ambient　temperature,　while　the　failure　mode　at　700　°C　is　different.　The　stiffness　and　strength　of　the　CRBCs　decrease　with　the　increasing　temperature.　Subsequently,　an　FE　model　considering　the　high-temperature　metal　fracture　is　established,　which　can　accurately　simulate　the　typical　failure　mechanisms　and　satisfactorily　predict　the　full　range　moment-rotation　behavior　of　CRBCs.　Furthermore,　parametric　analyses　are　conducted　to　investigate　the　influences　of　related　parameters　on　the　failure　mechanism,　initial　rotational　stiffness,　and　flexural　capacity　of　CRBCs.　Finally,　theoretical　models　based　on　the　component　method　are　established　for　calculating　the　initial　rotational　stiffness　and　flexural　capacity　of　CRBCs　at　high　temperatures,　respectively.　The　comparison　of　the　theoretical　model,　experimental　results,　and　numerical　results　indicates　that　the　theoretical　model　can　accurately　calculate　the　mechanical　properties　of　CRBCs　at　high　temperatures.　The　findings　of　this　study　can　provide　a　reference　for　the　analysis　and　design　of　the　fire　resistance　of　clad　rack　structures.　©　2022　Elsevier　Ltd
