Several papers have been written in the past about snow sliding tests and about the properties of snow sliding on a membrane roof. Those tests were done using an apparatus that were only several meters long. The static sliding friction properties of a largescale structure such as a dome may agree well with the results of those tests, however, as the sliding speed may differ much from those tests, it was necessary to develop an estimation method of resisting force when applying it to an actual structure. In this study, snow sliding tests were executed with an actual size membrane roof that is more than 40 meters long. As a result, it was learned that increase in sliding speed hardly influenced the kinetic friction force and it was proved that it is necessary to consider air resisting force in addition to viscostic resisting force in a large-scale structure.
