    For a low-cost and a resource-saving design of a plastic greenhouse, a simple pile foundation to prevent wind damage was examined.
The horizontal tension test was carried out for a small square steel pipe with L Width of 45 mm, which is generally used for part of the structure material of a plastic greenhouse. The results showed that the analysis method of the beam on a semi-infinite, ideal elastic medium is applicable to the calculation for a horizontal subgrade reaction of the small pile width.
    Moreover, we examined the pulling resistance of the pile, which is reinforced by a small steel pipe arranged in parallel crosses. This result suggests that this pile structure is useful for the methd of a simple and low-cost reinforcement of the greenhouse foundation.

Keywords: plastic greenhouse, coefficient of horizontal subgrade reaction, pile foundation, wind resistant design
