| Summary |
The plan of a building may have structural restrictions due to the weight of the snow on the roof in a snowy area. The bigger spans the structure has， the bigger restrictions it may have. Thus the stablishment of a system has long been hoped with which we can control snow sliding and lessen the snow load on the roof by making it slide down Recent studies have shown that snow sliding is subject to adfrcczing force
between the membrane material and the ice block.
In this study we made preliminary investigation on the forming process of adfreezing force between the membrane material and the ice block taking into consideration of weather conditions. And then. we carried out experiments on various membrane malarial assuming three types of adfreezing processes. As the result we identified
the adfreezing process for membrane material by examining the relation between its surface condition and the adfreezing process. Thus we the obtained basic data which we can use to establish a snow slide system for controlling the snow load on the roof.
