One　of　the　primary　factors　contributing　to　damage　in　building　structures　is　the　uneven　distribution　of　snow　on　roofs.　Specifically,　the　multi-span　gable　roof,　a　commonly　employed　design,　is　highly　susceptible　to　snow　loads　and　frequently　implicated　in　snow-related　collapse　incidents.　Consequently,　accurately　predicting　snow　distribution　on　this　type　of　roof　holds　significant　importance.　This　paper　presents　comprehensive　research　on　the　snow　load　distribution　on　multi-span　gable　roofs　by　employing　a　numerical　approach.　Initially,　the　viability　and　precision　of　this　numerical　method　were　verified　by　comparing　its　results　with　experimental　data.　Subsequently,　the　influences　of　inflow　wind　velocity,　inflow　wind　direction,　and　snowfall　intensity　on　snowdrifts　forming　on　multi-span　gable　roofs　were　explored　for　the　adverse　meteorological　conditions.　Lastly,　the　study　delved　into　the　impact　of　various　roof　shapes　on　snowdrifts　under　such　adverse　meteorological　conditions.　The　findings　reveal　that　the　roof　slope　plays　a　pivotal　role　in　determining　the　overall　snow　distribution　pattern,　while　the　aspect　ratio　of　the　roof　primarily　affects　snow　accumulation　amount　in　local　areas.　©　2024
