摘要(Abstract):

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.
