Light-frame　low-rise　buildings　are　widely　used　among　residences,　factories　and　other　infrastructures.　However,　many　post-disaster　surveys　reported　that　low-rise　buildings　suffer　serious　damages　during　strong　winds.　The　major　damage　mode　is　the　loss　of　envelope　components.　It　is　necessary　to　carry　out　studies　on　wind-induced　damage　analysis　of　low-rise　building　envelope.　An　approach　for　wind-induced　fragility　analysis　of　low-rise　building　envelope　was　proposed　based　on　a　simplified　3-stage　progressive　damage　process.　In　the　approach,　the　opening　condition　were　determined　by　identifying　failure　of　window/door　due　to　either　windborne　debris　impact　or　wind　pressures.　Internal　pressures　for　partially　enclosed　building　were　via　the　Bernoulli　equation.　Copula　function　was　used　to　analyze　the　associated　failures　of　roof　components.　A　general　procedure　for　fragility　analysis　was　proposed　based　on　Monte　Carlo　simulation.　A　wooden-frame　residential　building　was　used　as　an　example.　Furthermore,　the　effect　of　wind　directionality　was　studied.　Results　show　that　components　on　windward　wall　often　suffer　higher　risks　and　damage　on　building　envelope　may　be　underestimated　if　neglecting　the　effect　of　wind　directionality.　©　2021,　Editorial　Office　of　Journal　of　Building　Structures.　All　right　reserved.
