Skyscrapers are among the most distinctive building types of the modern age. Since many resources are attributed to these buildings, their design should consider a proper performance‐based construction economy and environmental sustainable development. This research introduces a new concept for a bundled tall building founded on the use of a multi‐core‐outrigger system, which is additionally enriched with diagrid structures. The concept is inspired by the bamboo plant and follows the biomimetic design principles for the structural organization and performance‐based criteria for optimizing the lateral stiffness and for shaping the cross section. Particularly, the incident wind speed is maximized to exploit Vertical Axis Wind Turbines (VAWTs), which are located along the whole building height at the center of the bundled towers. The building morphogenesis is accomplished by a multistep methodology that is fully developed in a parametric environment and includes structural and computational fluid dynamic analyses. With the aim of validating the proposed concept, a case study of a 320‐m‐tall three‐core building has been designed for the city of Pisa, Italy. The use of VAWTs results in an annual emissions reduction of about 10 kgCO2/m2.

捆绑式高层建筑的形态发生:结合DIAGrid的多核心支腿系统的仿生,结构和风能设计

摩天大楼是现代建筑中最具特色的建筑之一。由于这些建筑物有许多资源,因此其设计应考虑适当的基于性能的建筑经济和环境可持续发展。这项研究引入了一个基于多层核心支架系统的捆绑式高层建筑的新概念,该系统还附加了菱形结构。该概念的灵感来自竹子植物,并遵循仿生设计原则,用于结构组织和基于性能的标准,以优化侧向刚度和成形横截面。特别是,最大化入射风速以利用垂直轴风力涡轮机(VAWT),它们沿整个建筑高度位于捆绑塔的中心。建筑形态发生是通过在参数环境中完全开发的多步方法完成的,包括结构和计算流体动力学分析。为了验证所提出的概念,针对意大利比萨市设计了一个320层高的三核建筑的案例研究。VAWT的使用每年可减少约10吨的排放量 千克g C O 2 / m 2
