The distance between the rafters of the anti-disaster greenhouse is 50~60cm, and the rafter distance of the single-span greenhouse is 80~90cm. The wider the gap between the rafters, the more vulnerable the greenhouse is to wind and snow loads. Therefore, in this paper, the structural safety of the single-span greenhouse according to the basic wind speed of 40m/s and the depth of snow of 50cm, which are the design standards for the anti-disaster greenhouse, was verified through computational analysis. It was confirmed that the single-pipe foundation of the single-span greenhouse, could be pulled out by wind load, also it should be buried at least 50cm in soft ground to avoid subsidence due to snow load. When the combined strength ratio was reviewed, it was confirmed that the design conditions were not satisfied in all cases except for some roof parts. Therefore, a feasible reinforcement design for single-span greenhouse is needed to prevent damage due to wind and heavy snow loads.
