钢筋混凝土以扁平棱柱体形式浇注，在世界各地的多层建筑中占主导地位。尽管材料具有流动性，但通过操纵形状来创建有效几何形状的机会通常被忽视，导致低效的开裂部分，高钢要求和大碳足迹。该项目汇集了计算设计，材料和施工方面的现代发展，为多层建筑提出了一种新型的薄壳混凝土地板系统，为传统的钢筋混凝土平板创造了一种低能耗和轻质的替代品。在这项调查中，各种壳的几何形状的性能进行了比较，使用有限元分析。一个功能性的设计，并发现提供减少62%的体现能源和64%的重量相比，一个等效的平板。
Steel-reinforced concrete, cast in flat prismatic forms, dominates multi-storey building construction around the world. Despite the fluidity of the material, opportunities to create efficient geometries through manipulation of form are habitually overlooked, resulting in inefficient cracked sections, high steel requirements and large carbon footprints. This project brings together modern developments in computational design, materials and construction to propose a novel thin-shell concrete flooring system for multi-storey buildings, creating a low embodied energy and lightweight alternative to traditional reinforced concrete flat slabs. In this investigation, the performance of various shell geometries are compared using finite element analysis. A functional design is produced and found to offer reductions of 62% in embodied energy and 64% in weight compared to an equivalent flat slab.
