乌拉圭工程师Eladio Dieste开发了一种创新的大跨度屋顶结构施工方法。被称为高斯拱顶，它们的双曲线几何是基于接触网导致的主要轴向压缩力。虽然大多数薄的大跨度屋顶都是用混凝土建造的，但Dieste使用的是砖，而且与传统的砖石拱顶不同，它们只有一层砖的厚度。通常拱顶有一个低的上升，跨升比通常为8-10，屈曲是可能的破坏模式。Dieste利用拱顶的曲面来抵抗屈曲，并制定了设计程序来确保拱顶的安全。在本文中，简要介绍了Dieste的工作背景，包括他的分析方法，并参考了他的一个大型项目，蒙得维的亚码头的仓库，跨度为45米。通过一个迭代的数学过程，Dieste将悬链线拱的临界载荷表示成图形。方法……
The Uruguayan engineer Eladio Dieste developed an innovative construction method for wide-span roof structures. Known as Gaussian vaults, their double-curved geometry is based on the catenary resulting in mainly axial compressive forces. Whereas most thin wide-span roofs have been built using concrete, Dieste used brick, and unlike traditional masonry vaults, they are only one brick-layer in thickness. Typically the vaults have a low rise, the span-to-rise ratio is normally 8–10 and buckling is the likely mode of failure. Dieste used the curved surface of the vaults to resist buckling and developed design procedures to ensure their safety. In the present paper a brief background to Dieste's work is presented including his methods of analysis and the application is considered with reference to one of his larger projects, the warehouse at the docks in Montevideo, with a span of 45 m. Through an iterative mathematical procedure, Dieste formulated the critical loads of catenary arches into graphs. The method ...
