南朝鲜为举办1988年第24届奥运会,在汉城体育中心东南方向的2 km处,建造了可容纳13000名观众的体育馆和容纳7000名观众的击剑馆。它们的屋盖结构是一种拉索“圆形穹顶”,直径分别为119.79m和89.92m。这种“圆形穹顶”由连续的受拉素和不连续的受压立柱组成,因而被喻为“受拉海洋中的受压小岛”。较全部由受拉索组成的三角形网格球形穹顶,它具有矢高低、结构简洁、施工方便等优点,因而能提高经济效益。与气撑薄膜结构
In South Korea, for the 24th Olympic Games in 1988, 2km southeast of the Seoul Sports Center, a stadium with a capacity of 13,000 spectators and a fencing hall with 7,000 spectators were built. Their roof structure is a cable “round dome” with diameters of 119.79m and 89.92m, respectively. This “circular dome” consists of continuous receptors and discontinuous pressurized columns and is thus referred to as “the stressed island in the ocean of tension”. Compared to the triangular grid dome, which is composed entirely of cables, it has the advantages of low height, simple structure, convenient construction, and the like, and thus can improve economic efficiency.
