Assessing the Wind-Bearing Capacities of Plastic Greenhouse Frames Used in Southern China and the Performance of Reinforcement Measures

Buildings
To meet the growing requirements of agricultural mechanization, a newly designed 9.5 m span frame has been introduced to replace the traditional 8.0 m span frame, which is constrained by limited internal space.
