The test membrane structure was constructed in Iiyama city, that is extraordinary snowy area in Japan. Snow removal experiments were practiced in winter season of 1992-1993. We obtained the following results. (1)Two snow slip patterns were certified. The first pattern was occurred on the whole area of roof in snowing. The main cause of it was the deep snow on the roof. The other pattern was occurred on the each point position on the roof, and snow pieces were slipped down in step by step after snowing. The characteristic of snow on the roof were varied with the outside air temperature and the heat flux through the membrane. Snow slip patterns were depending in them. (2)When the snow falling vigorously, the heat quantities for real time melting were increasing. The heat quantities were calculated by the differential between the inside surface temperature of membrane and the under air temperature. (3)The low air temperature conditioning was useful to real time snow melting, and the snow on membrane was reduced effectively.
