The　adhesively　bonded　structure,　comprising　carbon　fiber-reinforced　polymer　(CFRP)　and　ultra-high-performance　concrete　(UHPC),　enhances　structural　strength　while　reducing　brittleness　and　strain　softening　behavior.　However,　the　adhesively　bonded　structure　is　inevitably　influenced　by　temperature　variations　throughout　its　service　life.　When　the　adhesive　layer＇s　temperature　surpasses　the　glass　transition　temperature　(Tg),　significant　damage　occurs　to　the　bond　layer　joint.　To　investigate　the　debonding　behavior　of　the　CFRP-UHPC　interface　at　various　temperatures,　a　series　of　three-point-bending　tests　were　conducted　at　room　temperature,　120　%Tg,　150　%Tg,　and　160　%Tg.　This　study　introduced　a　temperature　degradation　factor,　employing　a　proposed　maximum　load　capacity　prediction　formula　to　adjust　both　the　test　results　and　data　from　other　researchers.　By　adjusting　the　cohesion　parameters　with　the　temperature　degradation　factor,　a　temperature-dependent　mixed-mode　cohesive　zone　model　(CZM)　was　developed.　The　model＇s　validity　was　confirmed　through　finite　element　(FE)　analysis,　considering　two　distinct　experimental　scenarios.　The　paper　concludes　that　the　proposed　model　effectively　simulates　interface　debonding　behavior　across　varying　temperatures.　©　2024　Elsevier　Ltd
