| Summary | A series of field experiments on the artificial removal of snow from membrane structures were performed at Sapporo City this winter. The efficiencies of snow melting equipemnts for the different roof types were investigated with respect to the double membrane roof and to the single membrane roof with air circulating fans by employing a scale model of membrane structures. As for roof snow sliding mechanics. the starting friction coefficients of snow to the roof material and the tensile strengths of snow were closely investigated. Through these studies. the method of the removal of snow by artificially inducing snow slidings were proposed and tested by applying this method to removing the snow load from the scale model. The tests suggest that the possibilities of the practical applications of the method to remove snow loads from full scale membrane structures. |
