Title A STUDY ON SNOW SLIDING ON THE ROOF OF A MEMBRANE STRUCTURE
Author Tsukasa Tomabechi,Hideharu Yamaguchi,Masahiro Takakura
Summary The plan of a large structure may have problems related to the snow on the roof in a snowy area Since most of large structures have slanted roofs, the establishment of a method has long been hoped for by which we can control snow sliding and make the snow slide down smoothly. In this study we aim at a method of presuming snow sliding on the roof and making the snow slide down smoothly. We observed partial snow slides on a real roof. And then we analyzed the results and made an indoor experiments on partial snow sliding by using snow models. We investigated a condition of snow on the roof of a large membrane structure in a snowy area. And then we examined the relation of the results to the weather conditions. As a result, it became clear that partial snow sliding tends to occur easily either when the temperature of part of the roof is low or when there is much snow drift on the ridge. The roofing material and the shape of the roof have much to do with partial snow sliding.
