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。
Tension membrane structure and inflatable membrane structure is the main form of ETFE membrane structure. This paper analyzes the advantages of the spring-supported ETFE pillow-shaped membrane structure and the traditional inflatable membrane structure. In the existing ETFE spring-supported pillow-shaped membrane structure Based on the expansion of the original structural system by adding tie rods and splicing a single unit. ANSYS was used to find the shape of the new structural system analysis, snow load and stress analysis under wind load to calculate the membrane surface stress and membrane displacement, and compared with the existing structure.
