단동형 비닐하우스에 인장 타이 보강한 전후의 적설하중에 대한 거동 분석

This study aims to improve the flexural performance of single-span plastic greenhouses under snow load. These greenhouses, commonly found on farms in South Korea, frequently collapse during heavy winter snowfall. Based on experimental research showing the effectiveness of tensile-tie reinforcement among various strengthening methods, a theoretical analysis was conducted using the stiffness matrix method, and the reliability of both the experimental and analytical results was verified. Using the validated analysis method, the safety of several disaster-resistant greenhouse designs was evaluated to determine compliance with government disaster-resistance standards. The results indicate that the proposed safe snow depth of 200 mm may be adequate in regions with low snowfall or light snow. However, it presents a risk of collapse in areas with heavy snowfall, such as northern Gyeongsangbuk-do and Gangwon-du, during sudden snowfall exceeding 300 mm caused by abnormal weather conditions, or under wet snow conditions.
