A　proposed　asymmetrical　deck-type　concrete-filled　steel　tube　(CFST)　arch　bridge　with　a　span　of　380　m　was　analyzed　for　its　global　stability　in　both　the　construction　and　service　stages　by　using　Midas/Civil　7.0.　In　order　to　evaluate　the　influence　of　the　general　arrangement　of　the　proposed　bridge　on　its　stability,　the　buckling　modes　and　factors　of　the　proposed　bridge　and　another　two　bridges　were　compared.　The　two　bridges　are　the　same　as　the　proposed　bridge　except　that　they　are　symmetrically　arranged　and　have　the　spans　of　404m　and　358m,　respectively.　The　results　of　the　global　stability　analysis　demonstrate　that　the　bridge　has　adequate　safety　against　collapse　not　only　in　the　construction　stage　but　also　in　the　service　stage.　However,　the　asymmetrical　arrangement　of　the　proposed　bridge　reduces　its　stability.　The　load　carrying　capacity　is　lower　than　that　of　symmetrically　arranged　bridges　even　with　a　longer　span　length　of　404m.
