To　reveal　the　force　transmission　mechanism　of　a　novel　steel-concrete　joint　in　the　large-span　hybrid　continuous　girder　bridges，a　large-scale　model　of　a　steel-concrete　joint　with　a　geometric　scaling　ratio　of　1∶3.5　was　designed　and　fabricated　based　on　the　Fuzhou　Mawei　Bridge.　And　a　refined　solid　finite　element　method　was　also　used　for　static　loading　analysis　under　different　design　load　combinations.　The　results　show　that，under　the　load-bearing　capacity　limit　state　condition，the　concrete　girder　section　of　the　joint　model　was　fully　compressed.　The　maximum　compressive　stress　of　the　top-plate　concrete　at　the　joint　surface　was　-23.6　MPa，while　the　maximum　tensile　stress　of　the　bottom-plate　steel　was　115.8　MPa.　These　values　were　much　smaller　than　the　design　value　of　material　strength.　When　under　1.4　times　the　load-bearing　capacity　limit　state　condition，the　test　model　of　the　steel-concrete　joint　exhibited　no　marked　damage　during　the　static　loading　process.　The　load-displacement/strain　curves　of　measuring　points　on　each　control　section　basically　showed　a　linear　relationship，and　the　structure　was　always　in　an　elastic　working　state，indicating　that　the　joint　had　sufficient　safety　reserves.　The　vertical　deformation　of　each　section　of　the　steel-concrete　joint　had　no　sudden　change　along　the　longitudinal　direction，indicating　that　the　force　transmission　of　the　joint　was　smooth，which　can　ensure　that　the　rigidity　of　the　main　girder　was　steadily　transitioned　from　the　concrete　to　the　steel　box　girder　section.　The　relevant　research　findings　can　provide　a　reference　for　the　design　and　construction　of　such　hybrid　continuous　girder　bridges　in　the　future.　©　2023　Hunan　University.　All　rights　reserved.
