REuse of Structural sTeel in cOnstRuction (RESTOR)

钢结构建筑构成了英国绝大多数的多层和工业建筑。在现有建筑物中，超过85%的结构钢材在使用寿命结束时被回收利用，而重复使用的钢材不到15%。然而，钢铁回收是能源需求很高的行业，这使得英国钢铁行业成为能源需求和温室气体排放量最大的工业部门。因此，真正需要嵌入循环经济的尖端技术创新，最大限度地实现结构钢的可持续、高效和低能源再利用，而不是高耗能的回收。RESTOR是此类项目中第一个应用复杂的无损检测(NDT)、机器学习优化和建筑信息建模来在建筑中重复使用结构钢的项目。在旧钢构件(如梁、柱、支撑)的第一个使用寿命结束时，Restor将允许根据无损检测测量确定其材料特性。Restor将优化旧钢构件的再利用，并在其第二寿命内验证其结构性能。它将开发一种新的、经过验证和优化的最先进的生成性设计工具，该工具将创建由旧钢构件制成的自动化和优化的建筑配置。因此，Restor的产出将使计划作为后新冠肺炎经济复苏战略一部分的基础设施项目能够可持续地交付。

Steel buildings form the vast majority of multi-storey and industrial buildings in the UK. More than 85% of the structural steel in existing buildings is recycled at the end of their service life whereas less than 15% is reused. However, steel recycling is energy-demanding and contributes to the UK iron and steel industry being the largest industrial sector in terms of both energy demands and greenhouse gas emissions. Thus, there is a genuine need for cutting-edge technical innovations embedded in the circular economy that maximizes sustainable, efficient and low-energy reuse, rather than energy-demanding recycling, of structural steel.RESTOR is the first project of its kind to apply sophisticated non-destructive testing (NDT), machine learning optimization, and building information modelling to reuse structural steel in construction. At the end of the first lifespan of used steel members (e.g., beams, columns, braces), RESTOR will allow their material properties to be determined based on NDT measurements. RESTOR will optimize the repurposing of used steel members and validate their structural performance during their second lifespan. It will develop a new, validated and optimized state-of-the-art generative design tool that will create automated and optimized building configurations made of used steel members. The outputs of RESTOR will therefore enable sustainable delivery of the infrastructure projects planned as part of the post-COVID-19 economic recovery strategy.
