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。
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.
