Abstract
A damage occurrence of single-span type greenhouse by heavy snowfall in Korea, M shape collapse where excessive snow load of the roof occurs frequently regardless of the area damaging all the roof rafters. Therefore, in this paper, the snowdrift pattern of the arched house by shape using snow wind tunnel simulation is necessary. Experimental results indicated that the snowfalls on the roof of the arched house occur variously depending on the shape and location. As a result of estimating the load standard by roof slope angle and the values of snow loads using wind tunnel experiment, roof slopes showed 30% in 0°-15°and 80% in 45°-70° respectively, which were significant percentages in the snowdrift experiment.
