Membranes have high transmissivity within the visible-light range and are used in buildings to create a bright interior space. In regions with heavy snowfall, various means are used to remove snow from the roof of membrane structures in order to maintain a bright interior space during winter. However, the current evaluation of snow load on the roof of membrane structures is the same as that used for buildings from which snow removal is not frequently carried out. This is thought to be due to the current small number of membrane structures in regions with heavy snowfall and to insufficient clarification of the effectiveness of methods for removing snow from roofs. In this study, we carried out continuous observations of snow slide on the newly constructed Sapporo Community Dome in Sapporo. Hokkaido for the purpose of collecting data that may be used as a basis for appropriate evaluation of snow load on the roof of membrane structures in regions with heavy snowfall. The results showed that if the pitch of the roof of a membrane structure is more than 20°, natural snow slide will occur even when the outside air temperature is below 0℃. The data obtained in this study are useful for the evaluation of snow load on a roof.
