Greenhouses are vulnerable to wind loads due to the lightness of their structures. In fact, 98% of greenhouses damaged in 2019 are caused by wind loads. However, there are still many aging single-span greenhouses, so it seems that foundation reinforcement is essential to minimize damage due to meteorological disasters caused by climate change. Therefore, in this paper, we performed a computational analysis of the uplift capacity of the B and G type greenhouses with the wind load according to the Korean Design Standard(KDS). In addition, the results of computational analysis were compared with various foundation reinforcing methods studied by other researchers. It was confirmed that the single-pipe foundation, which is very common use, is very vulnerable to wind loads, the continuous pipe foundation is turned out to be unsuitable as a reinforcement method, except for areas with under 28m/s of basic wind speed. The spiral-type foundation also is confirmed to be unsuitable as a reinforcement method to G-type greenhouse. Therefore, it is necessary to develop a new type of reinforcement proposals for single-span greenhouse foundation.
