The test membrane structure was constructed with the glued laminated wood for structure use, in liyama city, that is extraordinary sonwy area in Japan. Snow removal experiments were practiced in natural conditions, in winter season of 1991-1992, and the characteristics of wood were investigated. We obtained the following results. ( 1 ) Two patterns of snow slip manners were certified. The first pattern was named as the whole slip-type. Snow at the bottom of roof was broken loose, and after few minutes, the whole snow on the roof was slipped down in a moment. The other pattern was named as the part slip-type. Many cracks were occured on the drifted snow, and the snow pieces were slipped down in step by step. ( 2 ) The method used in snow melting was useful to reduce the snow on the membrane. The efficiency was obtained by the heat quantities absorbed into the snow. ( 3 ) The glued laminated wood was suited for the structure material in snowy and cold area.
