At　present,　for　the　design　of　the　cable-net-stiffened　air-supported　membrane　structures,　the　model　is　usually　simplified　so　that　the　cable-net　and　the　membrane　surface　are　directly　connected,　ignoring　the　friction　and　slip　at　the　surface.　This　simplification　has　caused　great　hidden　risks　for　the　design　safety　of　the　membrane　structures.　Therefore,　using　the　ANSYS　software,　the　frictional　slip　between　the　cable　and　membrane　of　the　air-supported　membrane　structure　was　considered　as　a　contact　problem.　A　contact　model　was　established,　and　the　initial　shape　analysis　and　the　analysis　on　wind　load-induced　responses　were　carried　out.　The　results　show　that　when　the　influence　of　cable-membrane　contact　slip　is　not　considered,　the　restraint　effect　of　the　cable　net　on　the　membrane　surface　will　be　overestimated,　the　calculated　displacement　of　the　membrane　surface　is　too　small,　the　axial　force　of　the　cable　network　is　too　large,　and　the　phenomenon　of　stress　concentration　is　prone　to　occur.　When　the　cable-membrane　contact　slip　is　considered,　the　restraint　ability　of　the　cable-membrane　to　the　membrane　surface　decreases　significantly,　the　displacement　of　the　membrane　surface　increases　significantly　under　the　action　of　wind　load,　and　the　membrane　surface　and　the　cable-membrane　at　the　windward　side　even　separate.　Only　by　considering　contact　slip　analysis,　the　wind-induced　response　analysis　of　the　air-supported　membrane　structure　can　be　carried　out　correctly　to　avoid　the　occurrence　of　safety　accidents.　©　2022　Science　Press.　All　rights　reserved.
