摘要
北京世界园艺博览会演艺中心为骨架式膜结构体系,以大型钢构屋顶为骨架,在骨架上方张拉膜材.钢、索、膜三者结合,以钢索网支撑上部膜材.施工中通过建立模型深化精准定位焊接.通过二维材料的裁剪,焊接,张拉形成所需要的三维空间曲面,实现了不同颜色的膜材曲面搭接.
Bejjing International Horticultural Exhibition Performance Center is a skeleton membrane structure system,whose skeleton is a large steel structure roof covered by stretched membrane overhead.Materials were cut,welded and stretched to form three-dimensional space camber and membrane cambers of diferent colors were overlapped together.
