摘要
在膜结构找形方面,现有的方法多样,而找形结果误差往往较大。针对张拉型温室膜结构的几何非线性特点,以非线性有限元理论为基础,采用基于小弹性模量的支座提升法来对膜结构进行找形分析,研究其找形特点,同时得出一些对膜结构成功找形有益的结论。
On the form-finding analysis,this paper directed towards the geometrically nonlinear characteristics of the tension-type greenhouse membrane structure,based on nonlinear finite element theory,use the bearing upgrade method which is based on a small elastic modulus the form-finding analysis of the membrane structure is made and the characteristics of the membrane structure is studied,at the same time,draw some useful conclusions about the successful form-finding of the membrane structure.
