连栋塑料温室连栋数对结构体系安全性和稳定性的影响

Multi span plastic greenhouse structure safety and stability analysis in condition of different span numbers

以经过结构优化的连栋塑料温室构件为例 ,建立了不同栋数的结构模型 .在相同设计载荷及组合下 ,借助结构有限元分析软件进行理论分析 ,认为塑料温室结构的稳定性和相应的安全性随着连栋数的增加而有所提高 ,因此 ,相应的结构杆件截面优化值 。

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.
