Multi span plastic greenhouse structure safety and stability analysis in condition of different span numbers
连栋塑料温室连栋数对结构体系安全性和稳定性的影响

With optimized component of multi span plastic greenhouse structure, author established different span number's structure model, and analyzed model structure in the same load condition by use of optimum structural design theory and software of finite element analysis. The paper concluded that safety and stability of multi span plastic greenhouse structure would improve with span number increasing, and that optimized component of multi span plastic greenhouse structure was fit to assemble random span number's structure.
