The construction industry is a significant emitter of CO2, with an estimated contribution of 35% to global emissions. The production of cement constitutes a large part if this, and is responsible for 7% of global emissions. If nett zero targets are to be met in the UK by 2050, more sustainable structural solutions will need to be developed.The project aims to investigate more sustainable alternatives to conventional concrete floor slabs. In a first step, alternative materials (composite steel-concrete, stone, wood) and construction methods (arches, post-tensioning) will be investigated. A feasible alternative will be further developed into a technical solution. Particular attention will be devoted to arched concrete slabs on steel decking and the challenges of achieving composite action under combined bending and axial compression. Based on the attained understanding of the system's behaviour, a geometry optimization will be carried out.

建筑业是二氧化碳的重要排放者，估计占全球排放量的 35%。水泥生产占其中很大一部分，占全球排放量的 7%。如果英国要在 2050 年实现净零目标，则需要开发更可持续的结构解决方案。该项目旨在研究传统混凝土楼板的更可持续替代品。第一步，将研究替代材料（钢-混凝土复合材料、石材、木材）和施工方法（拱形、后张法）。可行的替代方案将进一步发展为技术方案。将特别关注钢甲板上的拱形混凝土板以及在弯曲和轴向压缩联合作用下实现复合作用的挑战。基于对系统行为的了解，将进行几何优化。
