Taking　Hejiang　Yangtze　River　Bridge　as　the　prototype,　the　trial　design　of　an　Ultra-high-Strength-Concrete　Filled　Steel　Tube　(UHSC-FST)　arch　bridge　is　conducted　in　this　paper.　Compared　with　the　prototype　bridge,　the　consumption　of　concrete　and　steel　materials　in　UHSC-FST　arch　ribs　are　reduced　by　14.3　and　4.4%,　respectively;　the　axial　force　of　the　UHSC-FST　arch　ribs　and　the　displacement　at　the　arch　crown　under　the　most　unfavorable　load　combinations　are　reduced　by　3.3~10.9　and　5.7%,　respectively;　the　ultimate　load-bearing　capacity　of　UHSC-FST　arch　rib　is　increased　by　42.0%.　It　is　indicated　by　the　analysis　results　that　UHSC-FST　arch　bridge　has　the　possibility　to　be　constructed　in　both　technical　and　economical　point　views,　and　it　is　worth　and　necessary　to　be　further　studied　on　this　topic.　©　The　Author(s),　under　exclusive　license　to　Springer　Nature　Switzerland　AG　2025.
