Before the rainy season, Greenhouse need appropriate wind protection measures, especially for areas exposed to strong winds. Additionally, the mid-frame structure, with its lower support density compared to the roof, is less stable and requires additional protection.
Building the Single Span Greenhouse on a windbreak on the leeward side can significantly reduce the pressure of strong winds on its front. Conversely, building it on the leeward side can significantly reduce the negative pressure that can cause the film to be lifted by strong winds.
During strong winds, the rate of gas exchange between the inside and outside of the Single Span Greenhouse is related to its degree of enclosure and wind speed. Therefore, precautions should be taken against damage caused by low temperatures and humidity.
When constructing a continuous greenhouse structure with high wind resistance, the wind load must be considered during the design phase. Wind resistance is positively correlated with the greenhouse's stability, which is closely related to factors such as the surface curvature, Greenhouse frame material, height-to-span ratio, and length-to-span ratio. Streamlined greenhouses have higher wind resistance.
Connected greenhouses can utilize the triangular stability principle, adding temporary supports, wires, pillars, or other frame materials between frames and between frames and the ground.
Open the vents and doors on the leeward side, or roll up part or all of the Greenhouse leeward side film from bottom to top. The purpose is to reduce the area affected by the negative pressure of strong winds and prevent the film from being blown off by strong winds.
