The　light-frame　low-rise　buildings　widely　used　for　residential　and　industrial　purposes　are　very　vulnerable　to　high　winds.　Postdisaster　surveys　indicated　that　envelope　components　such　as　windows,　doors,　and　roof　sheathings　suffer　significant　damages　due　to　wind　loads　and　windborne　debris.　Typically,　the　wind-induced　damage　process　for　a　low-rise　building　is　progressive　with　stochastic　openings　on　the　envelope.　In　this　study,　this　progressive　damage　process　is　simplified　as　three　stages,　i.e.,　the　nominally　sealed　building　with　background　leakage,　the　partially　enclosed　building　with　multiple　openings　on　walls,　and　the　loss　of　roof　sheathings.　Based　on　this　aforementioned　three-stage　process,　a　probabilistic　wind-induced　hazard　assessment　framework　for　the　light-frame　low-rise　building　envelope　is　developed.　Specifically,　two　approaches,　including　the　Monte　Carlo　simulation-based　approach　and　the　law　of　the　total　probability-based　approach,　are　developed　for　hazard　assessments　of　roof　sheathings　with　the　consideration　of　all　potential　opening　conditions.　A　numerical　example　is　adopted　to　illustrate　the　proposed　framework.　Results　show　that　these　two　approaches　assessing　the　wind-induced　hazard　for　a　low-rise　building　envelope　are　in　good　agreement,　and　the　latter　approach　has　an　efficiency　advantage.　(C)　2020　American　Society　of　Civil　Engineers.
