随着设计师提供可持续性驱动的结构解决方案的压力，在结构设计中充分利用资源变得至关重要。特别是，水泥是最大的二氧化碳贡献者之一，它在混凝土结构中的使用意味着优化以最大限度地减少材料和重量至关重要。优化设计技术，如骨生长类比，导致曲线和有趣的优化系统的非凡图像。然而，与实际建设的联系并不总是得到考虑。在进行这种优化的同时，世界各地的研究人员一直在研究使用柔性织物模板来浇注有趣的建筑混凝土结构。以前的研究并没有完全把美和最终几何的精确预测联系起来。本文介绍了巴斯大学最近的研究，该研究在美学吸引力、结构优化、最终几何形式的精确定义和施工实用性之间建立了联系。本文介绍了如何优化设计的柔性形成的混凝土结构元件可能会被设计和建造。结果表明，最终球根形状的准确预测是可能的，在任何部分的元素的结构能力的控制是可行的，并且高度美观的结果是可以实现的。
With pressure on designers to provide sustainability driven structural solutions, making best use of resources in structural design becomes paramount. In particular, cement is one of the greatest CO2 contributors and its use in concrete structures means that optimisation to minimise material and weight is crucial. Optimal design techniques, such as the bone growth analogy, result in extraordinary images of curvaceous and interesting optimised systems. However, the link to practical construction has not always been considered. Simultaneous with this sort of optimisation, various researchers around the world have been looking at the use of flexible fabric formwork for the casting of interesting architectural concrete structures. This previous research has not fully made the link between beauty and precise prediction of final geometry. This paper describes recent research at the University of Bath, which has created a link between aesthetic appeal, structural optimisation, precise definition of final geometric form, and practicality of construction. The paper describes how optimally designed flexibly-formed concrete structural elements may be designed and constructed. It is shown that accurate prediction of final bulbous shapes is possible, that control of structural capacity at any section of the element is feasible, and that highly-aesthetic outcomes are achievable.
