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.

尽管最先进的设计标准和最新的施工方法确保了建筑物在极端事件中拯救生命，但最近的统计数据显示，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供了一种新颖、可拆卸、有弹性和可持续的构建(DISC)技术。这个圆盘的灵感来自于人类脊柱的解剖，由一座多层的销钉钢架建筑和一个在现场制造并在施工现场组装的核心剪力墙组成。该壁由i)预制复合节段(椎骨)，ii)节段之间的新型高性能高性能聚合物缠绕复合丝材料(ECWM)薄层组成，以及iii)将这两层连接在一起的无粘结后张力筋。因此，脊椎在低幅度载荷(如风)下为结构提供横向稳定性，并抑制邻近地区列车引起的振动。当建筑物受到地震等极端荷载时，椎间盘会被压缩并抑制整个结构的运动，筋会重新定位整个建筑物的中心。因此，在极端事件发生后，该建筑仍可立即运行，即它具有弹性。这种阀瓣也是可持续和经久耐用的，因为它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。为了描述圆盘技术的动态行为和设计参数，首先建立了一个数值参数模型，并将通过全尺寸材料试验来表征ECWM的机械性能。将通过圆盘原型的中型振动台试验来验证圆盘的整体响应。根据这些结果，将构建一个新的可持续和基于复原力的设计框架，可供使用。
