Title Experimental Study on Resisting Force of Snow Sliding on the Roof of a Large-Scale Membrane Structure
Author Tatsuya Kotake,Tsukasa Tomabechi
Summary 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 large-scale structure such as a dome may agree well with the results of those testsüEîhoweverüEîas the sliding speed may differ much from those testsüEîit was necessary to develop an estimation method of resisting force when applying it to an actual structure. In this studyüEîsnow sliding tests were executed with an actual size membrane roof that is more than 40 meters long. As a resultüEîit 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.
