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近的施工方法确保了建筑物在极端事件中挽救生命，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供了一种新颖，可降低，弹性和可持续建筑（碟片）技术。该圆盘的灵感来自人类脊柱的解剖结构，由多层销钉钢制框架建筑物和一个由异地制造并在施工现场组装而成的核心剪切壁。壁由I）预制复合片段（椎骨），ii）在片段（椎间盘）（椎间盘）和III）之间的新型，高性能聚合物的薄层组成，纠缠的复合线材料（ECWM），无粘性的后张紧腱将这两个层绑在一起。因此，椎骨在低振幅载荷（例如风）下提供了结构的横向稳定性，并潮湿的振动是由相邻区域的火车引起的。当建筑物受到极端负荷（例如地震）时，椎间盘会被压缩并湿润整个结构的运动，肌腱将整个建筑物重新中心。因此，建筑物在极端事件发生后立即保持运行，即它具有弹性。该光盘还具有可持续性和耐用性，以应对环境威胁，因为它由玻璃纤维增​​强的聚合物组成，这些聚合物充满了纤维增强的混凝土和低碳复合材料。为了表征光盘技术的动态行为和设计参数，首先构建了数值参数模型，并且ECWM的机械性能将使用全尺度材料测试来表征。圆盘的总体响应将通过圆盘原型的中等尺寸摇桌测试来验证。从这些结果中，将构建一个可以使用的新的可持续性和基于弹性的设计框架。
