亚特兰大市佐治亚体育馆，美国
GEORGIA DOME, ATLANTA, USA, 1994
设计：魏德林格尔事务所
Design: Weidlinger Associates
　佐治亚体育馆的结构是一个空间桁架，其底部弦杆由环形索替代。这个屋顶为240m x 192m的椭圆形，是同类索膜结构中世界上最大的。它由涂有聚四氟乙烯的玻璃纤维膜覆盖。屋面呈钻石状，看上去象水晶一般。
　整个屋顶由7.9m宽、1.5m厚的混凝土受压环固定，共52根支柱支撑着700m周长的混凝土受压环，钢焊接件被预埋进受压环内，以提供26个屋顶连接点。为了使屋顶的热膨胀不影响下部结构，受压环座落在“特氟隆”承压垫上。这样，外力作用下承压垫只能径向移动，并可将风力和地震力均匀传向基础。
　脊索及底部环索上的连接件均为焊接件。这些接头沟通过钢板与其他杆件连接。飞杆的底部与斜索和环索固定，飞杆的连接件做成铰接件，以使其易于安装并在不均匀承重情况下允许接头旋转。

    The Tenstar Dome structure for the Georgia Dome incorporates a triangularized coble net with flying posts to create a tent--like appearance. the bottom of the flying posts are held back by diagonal cobles (attached to the top of the next outer ring) and are tied together with coble hoops. In effect, the structure is a truss in which the bottom chord is replaced by hoops that create a true three dimensional structural configuration. With an overall dimension of 240m x 192m, the roof is the largest such structure in the world. It is surfaced with diamond shaped panels of  PTFE coated glass fiber membrane, giving its outer skin a crystalline appearance.
    The roof is held by a compression ring that is a concrete box 7.9m wide x 1 .5m high. A total of  52 columns supports the 700m long perimeter of the ring. Steel weldments are embedded into the ring to provide the 26 attachment points for the cable dome. In order to permit the thermal expansion of the roof independent of the substructure, the compression ring sits on "teflon" bearing pads that are restrained to permit only radial movement. This arrangement permits both wind and seismic forces to be transmitted to the substructure.
    Connectors for both the ridge cobles and the bottom hoop cobles are weldments. These connectors are assembled from plates and permit continuous cobles to be clamped into saddles that provide for load transfer between cable and connector, and then to other cables or the posts. Attachment of the posts is accomplished with pinned connections, both to make the erection simpler and to permit rotation of the joint under non-uniform load conditions.
