Bond　failure　is　a　crucial　element　in　ascertaining　the　failure　mechanisms　of　reinforced　concrete　(RC)　structures.　The　investigation　pertaining　to　the　dynamic　loading＇s　impact　on　bond　efficacy　remains　a　lacuna　within　scholarly　discourse.　Therefore,　138　eccentric　pull-out　half-beam　specimens　have　been　fabricated　to　probe　the　intricate　degradation　mechanisms　underlying　the　bond-slip　phenomena　between　concrete　and　reinforcement　when　subjected　to　high-temperature　transients.　Initially,　a　series　of　experiments　were　conducted　on　half-beam　specimens　possessing　different　reinforcement　diameters　and　embedded　lengths.　Subsequently,　the　transient　temperature　changes　within　the　bond　segment　were　recorded,　and　this　was　pursued　by　the　execution　of　eccentric　pull-out　tests.　Second,　the　bond　stress-strain　curves　under　transient　temperature　were　measured.　The　experimental　findings　revealed　that　the　bond　strength　peaked　at　101　degrees　C　and　showed　an　upward　trend　up　to　302　degrees　C.　Beyond　this　temperature,　however,　the　bond　strength　exhibited　a　decline.　Specifically,　at　a　target　temperature　of　400　degrees　C,　the　bond　strength　increased　by　18.1%　and　9.3%　compared　to　values　at　20　degrees　C　and　200　degrees　C,　respectively.　In　contrast,　it　decreased　by　23.2%　and　41.3%　in　comparison　to　values　at　600　degrees　C　and　800　degrees　C.　Additionally,　as　the　reinforcement　diameter　increased,　there　was　a　decrease　in　bond　strength,　while　the　ultimate　failure　force　increased.　Finally,　a　methodology　for　evaluating　bond　strength　under　dynamic　temperature　was　introduced,　and　a　semiempirical　constitutive　model　was　formulated,　taking　into　account　the　interplay　between　different　heating　rates.　The　constitutive　model　underwent　validation　through　temperature　computations,　proposing　a　bending　moment　calculated　methods,　thus　affirming　its　accuracy　under　fluctuating　temperature　scenarios.
