“…Therefore, in addition to the permanent loads (self-weight of structural members, coverage material, fixed equipment), the structure must be built to withstand variable actions, such as wind and loads related to the crop (when applied), storm, hail, and snow (when applied) (Aldrich and Bartok, 1994;von Zabeltitz, 2011). Attention is required when considering accidental actions, given the large number of records of structural damage in greenhouses caused by strong winds and snow, with economic and crop losses, which can lead to the bankruptcy of horticultural companies (Briassoulis et al, 2016;Moriyama et al, 2015;Peña et al, 2020;Ryu et al, 2019;Wang et al, 2021).…”

The technology provided by greenhouses is essential for protecting crops sensitive to bioclimatic adversities and for improving agricultural production indexes. However, the need to know the exact interaction between the flexible coating and the structure under wind action has motivated new studies. The objective was to perform an in-depth review of the scientific and technological advances regarding methodologies to obtain parameters related to wind actions that are essential for the structural safety of greenhouses. This study showed the relevance of experimental methods; however, the limitations of the study are diverse, as field experiments require the construction and modifications of a prototype, which demand time and financial resources. Experiments in wind tunnels with models on a reduced scale have contributed significantly, as it allows to control the wind flow; however, in plastic-covered greenhouses, discrepancies occur due to the impossibility to represent the aeroelasticity of the construction. Modeling via computational fluid dynamics (CFD) has proven to be a solution for extrapolating limitations in experimental methods by facilitating changes in the construction model and wind flow. In addition to pure turbulence models, studies on hybrid turbulence models (Scale-Resolving Simulation) must be deepened to obtain greater accuracy of pressure coefficients. The complexity of the subject and the need for new contributions to plastic-covered greenhouse projects are a reality, which outlines a promising horizon for research development in the rural construction sector.

“…The wind pressure co-efficients for Evenspan, Three-quarter, Peach and Mono-span greenhouse structures were measured in the wind tunnel according to wind direction, roof slope and the radius of curvature of the roof. Ryu et al (2019) conducted a study on damage index estimation by analysis of meteorological disasters on film plastic greenhouses. Effect of typhoons, heavy snow, strong wind, and heavy rain on plastic film greenhouse were analyzed.…”

Naturally ventilated polyhouse is popular all over the world for growing high value cropssuch as capsicum, tomato, lettuce, herbs etc. and these polyhouses are available in different designs as per different climatic conditions. Structure failure is the major problem faced by farmers throughout the world. The several studies carried out throughout the world shows that the single design of polyhouse cannot be adopted throughout the country due to different agro-climatic conditions.As per differentstudies, polyhousestability designs are analyzed for dead load, live load, snow load, wind load and load combination and Loads were calculated by adoptingdifferent National Standards. Moreover, Truss members, columns and foundation stability analysis is carried out by considering dead loads, live loads and wind loads in most of the studies. Support reactions arealso calculated on truss joints and column joints. The optimum design of any polyhouse generally depends on its structural design, specific mechanical and physical properties of the individual structural components i.e., foundation, hoops, lateral support, polygrip, assembly and end frame. From all the studies it is reported that in most parts of the world, wind is the major force responsible for the failure of any polyhouse structure.

“…Typhoon accommodating heavy rainfall damage Korean agriculture during summer, in particular, property damage due to heavy rainfall accounted for about 70% of all agricultural meteorological disasters [ 15 ]. In spite of gradual disaster mitigation and prevention measures, meteorological disasters occur every year under various conditions and intensities in the case of heavy rainfall and typhoons [ 16 ]. Forage production has been also damaged severely by lodging [ 17 ].…”
