Before the rainy season, it is necessary to take corresponding windproof measures for multi span greenhouses, especially for the parts above the wind outlet. At the same time, for the waist skeleton of the greenhouse, due to the lower density of support points than the roof, the stability is slightly poor, so protection should also be strengthened.

If the multi span greenhouse can be built on the windward side wind barrier as much as possible, it can significantly reduce the pressure of strong winds on the front of the greenhouse; If built on the leeward side, it can significantly reduce the negative pressure lifting effect of strong winds.  

Establish a continuous greenhouse structure with high wind resistance, and consider the wind load of the greenhouse during design. The wind resistance is positively correlated with the stability performance of the greenhouse, which is closely related to factors such as surface curvature, greenhouse skeleton material, height span ratio, and length span ratio. Streamlined greenhouses have high wind resistance.

The connected shed can adopt the principle of triangular stability, by adding temporary or pull lines, pillars or shed materials between the sheds and the ground. Open the ventilation openings and doors on the leeward side of the greenhouse, or roll up some or all of the greenhouse film on the leeward side from bottom to top, in order to reduce the area affected by the negative pressure of strong winds and avoid lifting the film.

For the connected sheds located around the greenhouse film area, when the height is not lower than the strength of the middle shed, it can be appropriately reduced, which is beneficial to improve the overall windproof performance of the greenhouse film. In addition, damaged greenhouse films, exhaust holes, and doors should be repaired in a timely manner to prevent further damage.
