Although the most advanced design standards and recent construction methods ensure that buildings save lives during extreme events, recent statistics have shown that the global loss caused by extreme events is steadily growing. This proposal presents a novel, Demountable, Resilient, and Sustainable Construction (DISC) technology for next-generation infrastructure. The DISC, which is inspired by the anatomy of the human spine, is formed of a multi-storey pin-pin steel frame building and a core shear wall that is manufactured offsite and assembled on the construction site. The wall consists of i) precast composite segments (vertebrae), ii) thin layers of a new, high-performance polymer-based, entangled composite wire material (ECWM) between the segments (intervertebral discs), and iii) unbonded post-tensioning tendons that tie these two layers together. Thus, the vertebrae provide lateral stability of the structure under low-amplitude loading (e.g. wind) and damp the vibration resulting from trains in adjacent areas. When the building is subjected to extreme loading such as earthquakes, the intervertebral discs are compressed and damp the movement of the whole structure, and the tendons re-center the entire building. Thus, the building remains operational immediately after extreme events, i.e. it is resilient. The DISC is also sustainable and durable against environmental threats as it is composed of glass fibre reinforced polymer filled with fibre-reinforced concrete and low-carbon composite materials. To characterise the dynamic behaviour and design parameters of the DISC technology, a numerical parametric model is first constructed, and the mechanical properties of the ECWM will be characterised using full-scale material tests. The overall response of the DISC will be verified through medium-scale shaking table tests of DISC prototypes. From these results, a new sustainability and resilience-based design framework will be constructed that can be used.

虽然最先进的设计标准和最新的施工方法确保建筑物在极端事件中拯救生命，但最近的统计数据表明，极端事件造成的全球损失正在稳步增长。该提案为下一代基础设施提出了一种新颖的、可拆卸的、弹性的和可持续的建筑（DISC）技术。DISC的设计灵感来自人体脊柱的解剖结构，由多层别针钢框架建筑和核心剪力墙组成，核心剪力墙在工地外制造并在施工现场组装。墙体由i)预制复合段（椎骨），ii)节段（椎间盘）之间的新型高性能聚合物基缠绕复合丝材料（ECWM）薄层，以及iii)将这两层连接在一起的无粘结后张肌腱组成。因此，椎骨在低振幅荷载（例如风）下提供结构的横向稳定性，并阻尼相邻区域列车产生的振动。当建筑物受到地震等极端载荷时，椎间盘被压缩并阻尼整个结构的运动，肌腱将整个建筑物重新居中。因此，建筑在极端事件发生后仍能立即运行，即它具有弹性。由于DISC由玻璃纤维增强聚合物填充纤维增强混凝土和低碳复合材料组成，因此它具有可持续性和耐用性，可以抵御环境威胁。为了描述DISC技术的动态行为和设计参数，首先构建了一个数值参数模型，并将使用全尺寸材料测试来表征ECWM的机械性能。DISC的整体响应将通过DISC原型的中尺度振动台试验进行验证。根据这些结果，将构建一个新的可持续性和弹性设计框架。
