Ultra-high　performance　concrete　(UHPC)　has　been　widely　used　in　wet　joints　of　precast　bridge　deck　panels　(PBDPs)　due　to　its　remarkable　compressive　strength,　excellent　tensile　strength,　and　exceptional　durability　properties.　However,　there　is　a　lack　of　consistent　understanding　regarding　the　mechanical　properties　of　PBDPs　with　UHPC　wet　joints,　especially　shear　behavior.　To　investigate　the　shear　performance　of　PBDPs　with　UHPC　wet　joints,　a　total　of　seven　bridge　deck　panels　(BDPs)　were　designed　and　conducted　by　four-point　bending　tests.　The　test　parameters　included　reinforcement　types　(straight　bar　and　U-bar),　lap　details　(contact　lap　and　non-contact　lap),　joint　widths　(150　mm,　200　mm,　250　mm,　and　500　mm),　and　filling　materials　(NC　and　UHPC).　According　to　the　test　results,　the　shear　behavior　of　seven　BDPs　was　analyzed.　The　experiment　results　showed　that　all　specimens　exhibited　shear　failure,　with　critical　shear　cracks　occurring　in　the　shear　span.　For　PBDPs　with　U-bars,　the　shear　capacity　of　200-mm-wide　UHPC　wet　joints　was　1.5　%　higher　than　that　of　500-mm-wide　NC　wet　joints.　In　addition,　the　failure　pattern　had　a　tendency　to　gradually　shift　from　shear　failure　to　flexural　failure　when　the　width　of　UHPC　wet　joints　was　reduced　from　250　mm　to　150　mm.　To　establish　3D　finite　element　(FE)　models,　a　cohesion-friction　hybrid　model　was　proposed.　The　FE　models　had　good　simulation　accuracy,　with　a　maximum　deviation　of　7.0　%.　Furthermore,　a　parametric　analysis　was　performed　to　assess　the　influence　of　critical　parameters　on　shear　performance.　The　results　showed　that　longitudinal　reinforcement　has　a　greater　influence　on　the　shear　performance　of　PBDPs.　Finally,　shear　capacity　formulas　in　the　design　codes　were　verified　in　comparison　with　test　results.　The　deviation　of　theoretically　calculated　values　from　test　results　was　within　10　%.
