Abstract：

To　improve　the　durability　design　level　of　the　foundation　bearing　platform　for　offshore　fixed　wind　power,　Ultra-high　performance　concrete　(UHPC)　is　used　as　a　non-demolding　membrane　shell　system,　and　a　high-performance　composite　concrete　bearing　platform　structure　is　formed　with　on-site　pouring　of　core　concrete.　The　interface　performance　between　the　prefabricated　UHPC　membrane　shell　and　the　post　cast　core　concrete　has　become　an　important　aspect　of　the　overall　integrity　of　the　high-performance　composite　concrete　bearing　platform.　The　use　of　interface　shear　key　design　to　improve　interface　integrity　is　necessary　for　improving　the　overall　stress　of　the　bearing　platform　structure.　The　objective　of　this　study　is　to　assess　the　effect　of　the　internal　span　on　the　shear　behavior　at　the　junction　of　UHPC　and　normal　concrete　(NC).　©　The　Author(s),　under　exclusive　license　to　Springer　Nature　Singapore　Pte　Ltd.　2025.
