The　creep　models　specified　in　the　ACI　209R-92　and　the　CEB-FIP　MC90　are　both　commonly　used　in　predicting　the　creep　of　concrete　in　Concrete-filled　Steel　Tube　(CFST)　arch　bridges　in　China.　A　lot　of　experimental　researches　showed　that　the　ACI　209R-92　model　predicted　better　creep　result　for　CFST　specimens　than　the　CEB-FIP　MC90　did.　However,　most　of　the　Chinese　designers　are　more　familiar　with　the　CEB-FIP　MC90　model　recommended　by　the　Code　for　Design　of　Highway　Reinforced　Concrete　and　Prestressed　Concrete　Bridges　and　Culverts　(JTG　D62-2004,China).　In　this　paper,　the　creep　effects　of　two　CFST　arch　bridges　in　ten　years　after　bridge　completion　are　predicted　by　the　two　creep　models,　and　also　the　results　are　analyzed.　It　is　shown　from　the　case　studies　that　the　maximum　difference　between　the　results　with　the　ACI　209R-92　and　CEB-FIP　MC90　models　is　less　than　5　%.　Therefore,　both　ACI　209R-92　and　CEB-FIP　MC90　models　have　the　similar　creep　analysis　results　and　could　be　used　in　engineering　practice　before　more　precise　model　is　presented.
