Enhancing Performance And Sustainability Of Agricultural Greenhouse Structures Exposed To Wind Through Obstruction Strategies

The ever-increasing urban population necessitates the cultivation of crops in greenhouses within societies. Greenhouse structures are meticulously designed to facilitate optimal growth conditions, including heat, temperature and humidity for agricultural produce. However, the persistent threat of wind load poses a significant challenge to these structures, a challenge that is further exacerbated by the impacts of climate change. Thus, it is imperative for designers to proactively account for changes in wind patterns, enhancing the performance of greenhouses against extreme weather events. To address this concern, the integration of physical obstructions has been proposed, serving not only to bolster structural safety but also to enhance the sustainability of crop cultivation practices. In a bid to evaluate the efficacy of these measures, two real-world structures underwent simulation using SAP۲۰۰۰ software and were analyzed using Python programming, with a focus on assessing the impact of barriers on greenhouse performance. The findings reveal that these obstructions can enhance greenhouse performance for two models by ۲۶% and ۱۲.۶% respectively. Thereby offering supplementary energy resources for maintenance activities within the greenhouse environment. Furthermore, implementing this measure, applicable to both existing and new structures, will result in a decrease in maximum deflection by up to ۳۰% in single-span structure and ۱۳% in double-span greenhouse.
