Sustainable solutions for structural floor systems

建筑业是二氧化碳的主要排放源，估计占全球排放量的35%。水泥的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年前实现净零排放目标，就需要开发出更具可持续性的结构性解决方案。该项目旨在研究传统混凝土楼板的更可持续的替代品。在第一步，替代材料（组合钢-混凝土，石头，木材）和施工方法（拱，后张拉）将进行调查。一个可行的替代方案将进一步发展成为技术解决方案。将特别关注钢甲板上的拱形混凝土板，以及在弯曲和轴压联合作用下实现复合作用的挑战。基于对系统行为的理解，将进行几何优化。

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.
