The　Annular　Crossed　Cable-Truss　Structure　(ACCTS)　is　a　new　type　of　Tensile　Spatial　Structure　with　a　configuration　suitable　to　cover　large-span　stadiums.　Its　configuration　has　potential　to　perform　well　in　resisting　disproportionate　collapse.　However,　its　disproportionate　collapse　resistance　hasn＇t　yet　been　analyzed　in　depth.　In　this　study,　numerical　and　experimental　research　was　carried　out　to　investigate　the　performance　of　ACCTS　under　cable　rupture.　The　numerical　analysis　was　done　for　ten　cable-rupture　plans　using　LS-DYNA　(explicit　method)　and　the　experimental　test　on　an　ACCTS　with　a　diameter　of　17.15　m　was　performed　for　three　cable-rupture　plans.　It　is　concluded　that,　while　deflections　increase　with　the　number　of　removed　cables,　an　ACCTS　does　not　undergo　a　disproportionate　collapse　and　it　provides　a　promising　structural　concept　for　tensile　spatial　structures.
