摘要
黄河水利职业技术学院风雨球场张拉膜结构是由跨度86.4m的桁架拱、空间钢桁架和张拉膜系统组成的新型空间结构体系。采用有限元软件ANSYS对结构体系在各种荷载作用下的受力和变形规律进行了探讨,特别讨论了索膜的受力和变形情况。分析结果认为,膜的找形结果满足设计和使用要求。柔性膜结构的大变形使膜单元和索单元应力退化,特别是在风升作用下,脊索应力有明显的损失。边索和钢拱的连接部位受力和变形较大,应加设侧向支撑和腹杆。
The tensioned membrane structure of the gymnasium of Yellow River Hydrotechnical Vocational Institute （YRHVI） is a new-typed system of space structure, which consists of an arch-truss with the span of 86,4m, special steel truss and tensioned membrane system. The finite element software ANSYS is used to calculate the laws of stressing and deformation of structure, especially the cable-membrane structure, under various sorts of loads so that some useful results for project designing can be obtained, which will provide certain reference for other similar projects.
