SS-DSC: Stainless steel-concrete composite beams with stainless-steel demountable shear connectors for sustainable infrastructure

这个项目将评估钢-混凝土组合梁(用于建筑物或桥梁)的结构性能，这些组合梁的不锈钢部分通过可拆卸的连接件连接到预制的混凝土板上。由不锈钢材料制成的组合桥梁将具有更高的耐久性，它们不容易腐蚀，而且需要的维护更少。如果需要，混凝土甲板将很容易更换，并将停机时间和交通中断降至最低。此外，所有部件将在桥梁或建筑物的使用年限内重复使用，这符合循环经济模式，并将有助于实现建筑部门的净零目标。组合梁将通过实验室中的一系列实验测试和高级数值模拟进行评估。将利用生命周期评估工具来评估拟议组合梁的生命周期成本和环境性能。

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.
