A Study on the Snowdrift Patterns of Gable and Flat Roofs Using a Wind Tunnel

Abstract:

Snowdrift patterns exhibit various forms according to the architectural shapes and models. As snowdrift patterns largely influence the snow loads that buildings have to withstand, a number of studies have been conducted. This study examines snowdrift patterns and how the amount of snow comes to rest depends on the shape of a roof (for flat and gable roofs) using a wind tunnel test. An analysis of snowdrift patterns and accumulation coefficients, which are representative of the depth of snow cover, for flat and gable roofs showed that accumulation coefficient decreases in accordance with increases in wind speed. The gable roof exhibited a slightly higher accumulation coefficient than the flat roof.
