| 摘 要： | 张拉式膜结构和充气式膜结构是ETFE薄膜结构的主要形式,该文分析了弹簧支撑ETFE枕式膜结构与传统充气式膜结构的优势,在已有的ETFE弹簧支撑枕式膜结构的基础上,通过增加拉杆和进行单个单元的拼接,对原有结构体系进行拓展。利用ANSYS对新结构体系进行了找形分析、雪荷载和风荷载下的应力分析,计算膜面应力和膜面位移,并与已有结构进行对比。

| Abstract: | Tensile membrane structures and inflatable membrane structures are the two forms of traditional ETFE foil structures.In this paper,a new ETFE foil spring cushion structural system was developed and compared with the traditional ETFE foil air cushion system.Two numerical models,i.e.a spring cushion unit model with tension rods in it and a spring cushion model with two units,were analyzed by means of ANSYS software package.The shape-finding analysis and stress analysis considering snow loading and wind loading were carried out.The structural behaviors of an ETFE foil spring cushion system were investigated. |
