Several　concrete-filled　steel　tube　(CFT)　arch　bridges　have　been　built　over　the　past　few　years　around　the　world.　Current　design　codes　do　not　address　the　design　of　CFT　arch　bridges,　particularly　with　consideration　of　concrete　creep　effects,　which　can　be　very　important.　This　paper　presents　experimental　results　from　tests　conducted　on　13　specimens　to　evaluate　the　creep　behavior　of　CFT　members.　An　experimental　database　was　compiled　using　results　from　this　paper　and　35　additional　tests　from　the　literature.　The　comprehensive　database　was　used　to　evaluate　four　commonly　used　creep　models　for　predicting　short-term　(up　to　730　days)　creep　strains　of　the　concrete　infill　in　CFT　members.　The　selected　models　are　the　Comite　Euro　International　du　Beton-Federation　Internationale　de　la　Precontrainte　(CEB-FIP)　MC90　model,　federation　internationale　du　beton　(fib)　MC2010　model,　American　Concrete　Institute　(ACI)　209　R-92　model,　and　the　B4　model.　The　evaluations　indicate　that　the　prediction　quality　varies　by　cases.　Therefore,　it　is　not　possible　to　recommend　a　most-suitable　model　based　on　this　study.　Further　investigations　are　required　to　evaluate　the　effects　of　factors　such　as　the　steel　ratio.　To　evaluate　the　effects　of　creep　on　the　time-dependent　behavior　of　CFT　arch　bridges,　creep　analyses　on　11　such　bridges　were　conducted　with　the　implemented　ACI　209　R-92　creep　model.　Analytical　results　indicate　that　creep　results　in　increases　in　the　steel　tube　stresses　and　bridge　deflections　and　relaxation　of　concrete　stresses.　(C)　2017　American　Society　of　Civil　Engineers.
