Light　steel　houses　are　widely　used　in　low　rise　buildings,　such　as,　residential　and　factory　buildings.　This　type　structures　are　lightweight　and　more　sensitive　to　wind　load,　and　they　are　severely　damaged　in　typhoons　to　cause　huge　economic　losses.　Therefore,　performing　wind　disaster　assessment　for　this　type　structures　is　of　great　significance.　Here,　firstly,　based　on　random　simulation　technique,　the　analysis　framework　for　wind　induced　vulnerability　of　a　whole　light　steel　house　was　proposed,　it　was　related　to　wind　load　randomization　methods,　wind　induced　brittleness　analysis　methods　for　main　structure　and　enclosure　structure,　and　wind　induced　vulnerability　analysis　process　for　house　whole　structure.　Secondly,　a　case　study　was　performed　for　wind-induced　vulnerability　of　a　specific　light　steel　structure　based　on　the　proposed　framework.　The　results　showed　that　the　proposed　method　can　better　consider　the　joint　action　of　flying　objects　and　wind　pressure　as　well　as　the　internal　pressure　change　effect　caused　by　the　joint　action;　it　can　also　fuse　wind　disaster　losses　of　main　structure　and　whole　enclosure　structure　to　obtain　vulnerability　curve　of　whole　structure　of　a　light　steel　house.　©　2024　Chinese　Vibration　Engineering　Society.　All　rights　reserved.
