In　view　of　the　problem　that　the　influences　of　the　robustness　of　half-through　and　through　arch　bridges　can　not　be　reflected　in　the　current　technical　condition　evaluation　systems,　a　technical　condition　evaluation　method　considering　the　robustness　of　the　suspended　floor　systems　of　the　bridges　was　put　forward.　A　half-through　concrete-filled　steel　tube　arch　bridge　was　selected　as　an　example　and　for　the　3　types　of　the　floor　system　structures　having　their　cross　beams　as　the　main　load　bearing　components,　the　technical　condition　evaluation　of　the　superstructure　of　the　bridge　was　implemented,　respectively　using　the　current　standards　and　the　evaluation　method　considering　the　robustness.　The　results　yield　that　when　the　robustness　of　the　floor　systems　is　not　considered,　the　evaluation　of　the　bridge　following　the　Standards　for　Technical　Condition　Evaluation　of　Highway　Bridges　(JTG/T　H21-2011)　is　that　the　more　the　numbers　of　the　stringers　on　the　bridge　are,　the　fewer　scores　the　structure　will　have.　The　evaluation　following　the　Technical　Standard　of　Maintenance　for　City　Bridge　(CJJ　99-2017)　is　that　the　3　floor　system　structures　are　defined　as　the　＇unqualified＇　and　all　of　the　evaluation　of　the　two　standards　is　not　reasonable.　When　the　robustness　of　the　floor　systems　is　considered　and　on　condition　that　the　other　evaluation　conditions　are　the　same,　the　evaluation　of　the　bridge　is　that　the　better　the　robustness　is,　the　better　the　technical　conditions　of　the　structure　of　the　bridge　will　be.　The　technical　condition　evaluation　method　considering　the　robustness　can　better　reflect　the　real　conditions　of　the　bridge　and　can　well　accommodate　to　its　maintenance　and　management　requirements.　©　2018,　Journal　Press,　China　Railway　Bridge　Science　Research　Institute,　Ltd.　All　right　reserved.
