折板屋根先端における氷柱形成

抄録

Folded-plate roofs are used as roof materials for many large-scale facilities because they are inexpensive and easily constructed. However, in snowy regions in winter, the edges of folded-plate roofs generate large icicles. Great costs are expended to prevent damage caused by falling icicles. This study was conducted using model experiments to clarify the icicle formation mechanism at edges of a folded-plate roof and to elucidate methods of preventing icicle growth without electricity.
