In the context of tall building design, the tube concept represents one of the most performing systems. The diagrid is the widespread type of tube system and consists of a diagonal grid of beams that wraps the building, forming a diamond pattern. It performs as lateral bracing and is additionally able to sustain vertical loading through axial forces. Despite its efficiency, a growing interest is recently observed in alternative geometries to replace the diagrid pattern and improve the architectural impact conferred by the building skin aesthetics on the urban environment. The paper pursues the use of a Voronoi mesh, in which the geometry of the cells is steered to known schemes for the structural design of a cantilever tube structure. The objective is to mimic a macroscopic structural behavior through a topology and size modification of the Voronoi mesh that increases the density for creating resisting paths with higher stiffness. The paper proposes a novel method Vorogrid for designing a new class of tall buildings equipped with an organic-looking and mechanically sound tube structure, which makes them a valuable alternative to competitors (diagrid, hexagrid, random Voronoi). Diagrids and hexagrids still remain more efficient in terms of forces and displacements but are characterized by a more usual appearance, instead Vorogrid offers more design control and better performances on average with respect to random Voronoi structures. This method is streamed into a pipeline that includes grid initialization strategies, geometric and structural optimization to mitigate the effects of the grid randomness, and structural sizing.

Vorogrid：一种静态感知可变密度 Voronoi 网格，用于设计高层建筑的管状结构镶嵌

在高层建筑设计的背景下，管道概念代表了性能最高的系统之一。斜肋构架是一种广泛使用的管系统，由包裹建筑物的对角线网格梁组成，形成菱形图案。它用作横向支撑，并且还能够通过轴向力承受垂直载荷。尽管效率很高，但最近观察到人们越来越关注替代几何形状，以取代斜肋构架图案并改善建筑表皮美学赋予城市环境的建筑影响。该论文追求使用 Voronoi 网格，其中单元格的几何形状被引导到悬臂管结构的结构设计的已知方案。目的是通过 Voronoi 网格的拓扑结构和尺寸修改来模拟宏观结构行为，从而增加密度以创建具有更高刚度的阻力路径。本文提出了一种新颖的 Vorogrid 方法，用于设计配备有机外观和机械声音管结构的新型高层建筑，这使其成为竞争对手（斜肋网格、六边形网格、随机 Voronoi）的有价值的替代方案。斜交网格和六边形网格在力和位移方面仍然更有效，但具有更常见的外观特征，而 Vorogrid 提供了更多的设计控制和相对于随机 Voronoi 结构的平均更好的性能。此方法被流式传输到包含网格初始化策略的管道中，
