建筑业占英国碳排放量的近一半，主要原因是大量使用混凝土。混凝土的传统模板方法产生具有恒定横截面的棱柱形建筑元件，但是梁必须承受的剪切力和弯矩沿其长度沿着远不是恒定的。典型梁中高达40%的混凝土可以被移除。一个迭代优化过程中已实施的参数化建模框架，以生成和分析最佳形式的非棱柱形梁，考虑到制造过程中施加的约束，即使用织物模板。由此产生的设计工具的目的是促进通过非棱柱体元素的建筑行业。
The construction industry is responsible for nearly half of the UK’s carbon emissions, mainly due to the large amount of concrete used. Traditional formwork methods for concrete result in prismatic building elements with a constant cross-section, but the shear forces and bending moments that beams have to withstand are far from constant along their length. Up to 40% of the concrete in a typical beam could be removed. An iterative optimisation process has been implemented in a parametric modelling framework to generate and analyse optimal forms for non-prismatic beams that take into account the constraints imposed by the fabrication process, namely the use of fabric formwork. The aim of the resulting design tool is to facilitate the adoption of non-prismatic elements by the construction industry.
