This project will assess the structural behaviour of steel-concrete composite beams (for buildings or bridges) that have stainless-steel steel sections connected to precast concrete slabs with demountable connectors. Composite bridges made of stainless-steel material will have a significantly greater durability, they will not be prone to corrosion, and they will require less maintenance. The concrete decks will be easily replaced, if needed, with minimum downtime and disruption to traffic. In addition, all components will be reusable at the and of life of a bridge or building, which is in line with a circular economy model and will help to achieve the net-zero target in the construction sector. The composite beams will be assessed through a series of experimental tests in the Labs and advanced numerical simulations. Life cycle assessment tools will be utilized to evaluate the life-cycle costs and environmental performance of the proposed composite beams.

该项目将评估钢-混凝土组合梁（用于建筑物或桥梁）的结构性能，该组合梁具有通过可拆卸连接器连接到预制混凝土板的不锈钢钢截面。由不锈钢材料制成的复合材料桥梁将具有更高的耐久性，不易腐蚀，并且需要更少的维护。如果需要，混凝土甲板将很容易更换，停机时间和交通中断最小。此外，所有组件都将在桥梁或建筑物的寿命结束时可重复使用，这符合循环经济模式，并将有助于实现建筑行业的净零目标。复合梁将通过实验室的一系列实验测试和先进的数值模拟进行评估。生命周期评估工具将被用来评估拟议的组合梁的生命周期成本和环境性能。
