抄録
As a measure to prevent snow from accumulating on horizontal beams that support road information signs in cold、 snowy regions、 a tilted stepped plate was developed on a trial basis from conventional tilted flat plates、 and was subjected to testing. As a result、 snow fell from the tilted stepped plate more frequently than from the tilted flat plate、 and the depth of the accumulated snow at the time of falling was less than 30 cm. The test suggested that one of the reasons for this was voids created in the snow accumulated on the tilted stepped plate、 which divided the snow into smaller sections and helped it fall off easily.
