Annular　crossed　cable-truss　structure　(ACCTS)　is　a　novel　flexible　cable-strut　tensile　structure.　Its　stiffness　is　generated　from　the　prestresses　of　cables,　and　the　prestresses　of　cables　is　mostly　controlled　by　the　deformation　of　cables.　So,　it　is　necessary　to　study　the　influence　of　cable　length　errors　on　ACCTS　and　the　method　of　solving　control　criteria　of　cable　length　errors.　According　to　sensitive　analysis　of　cable　length　errors,　the　sensitive　indexes　of　all　kinds　of　cables　are　gained,　and　the　influences　of　ear-plate　and　cable　on　ACCTS　are　larger　and　the　influences　of　struts　on　ACCTS　are　smaller.　Then　define　ear-plate　and　cable　as　sensitivity　components,　and　define　strut　as　non-sensitivity　component.　Based　on　sensitive　analysis,　reliability　theory　and　nonlinear　programming　theory,　the　method　solving　control　criteria　of　cable　length　errors　for　ACCTS　is　proposed.　By　the　method,　the　control　criteria　of　cable　length　errors　under　4　conditions　are　studied.　The　model　trial　of　sensitive　analysis　of　ACCTS　with　a　diameter　of　6　m　was　carried　out.　The　results　show　that　the　influences　of　cable　length　manufacturing　errors　on　ACCTS　are　solved　by　sensitive　analysis　and　the　proposed　method.　The　distribution　of　control　criteria　of　cable　length　errors　is　uniform,　and　can　meet　the　requirements　of　China　and　US　Codes.　The　trial　values　are　consistent　with　the　simulation　values.　The　results　provide　the　acceptance　criteria　for　ACCTS,　which　promotes　the　application　of　ACCTS　in　practical　engineering.
