项目摘要

Man-made extreme events (i.e., terrorist attacks, impacts, explosions, and fires) can cause local damage to structures which may spread from element to element leading to the collapse of the entire structure or a large part of it, i.e., progressive collapse. These are among the most severe events in terms of casualties, economic losses, and societal impact, as has been made evident by several cases, e.g., the progressive partial collapse of the Champlain Towers in 2021. The RESTORE project proposes an innovative framework to assess the progressive collapse risk of existing Steel and Reinforced Concrete (RC) buildings subjected to man-made hazards and design robustness- and resilience-enhancing solutions. The project investigates innovative retrofit solutions, including combinations of global and local interventions, aiming for a trade-off between benefits and drawbacks of both strategies, thus enabling effective retrofit interventions against multiple hazards. They will:- ensure structural redundancy, mitigating progressive collapse risk against multiple-hazards (robustness)- provide an alternative to the demolish-and-rebuild strategy, allowing for the re-use of existing structures and the reduction of environmental impact (sustainability and low CO2 emissions)- have low invasiveness on the ordinary functions of the building during the installation (low business interruption)- minimise the probability of collapse under extreme events (protection of human life)- experience minimal damage that can be rapidly repaired (high resilience for strategic buildings)The excellence of the research facilities and courses for young researchers of the host institution (UCL, ranked among the world's top 10 universities), the Supervisor's expertise, and the involvement in the project of academic partners and of a high-profile industrial collaborator (ARUP) guarantee a high scientific value, the completion of the project and the exploitation of the achieved results in practice.

人为的极端事件（即，恐怖袭击、撞击、爆炸和火灾）可对结构造成局部损坏，该局部损坏可从一个元件扩散到另一个元件，导致整个结构或其大部分倒塌，即，渐进式坍塌就伤亡、经济损失和社会影响而言，这些都是最严重的事件之一，若干案例表明了这一点，例如，尚普兰塔将于2021年部分倒塌RESTORE项目提出了一个创新框架，用于评估遭受人为危害的现有钢和钢筋混凝土（RC）建筑的逐渐倒塌风险，并设计增强鲁棒性和复原力的解决方案。该项目研究创新的改造解决方案，包括全球和地方干预措施的结合，旨在权衡两种战略的利弊，从而能够针对多种危害采取有效的改造干预措施。他们将：- 确保结构冗余，减轻多重灾害造成的连续倒塌风险（稳健性）-为拆卸重建策略提供另一个选择，容许重新使用现有建筑物及减少对环境的影响（可持续性和低CO2排放）-在安装过程中对建筑物的普通功能具有低侵入性（低业务中断）-最大限度地减少极端事件下的崩溃概率（保护人类生命）-遭受最小的损坏，可以快速修复（战略建筑物的高复原力）主办机构为年轻研究人员提供卓越的研究设施和课程（伦敦大学学院，世界排名前10的大学之一），主管的专业知识，并在学术合作伙伴和一个高调的工业合作者（ARUP）的项目参与保证了高科学价值，项目的完成和在实践中取得的成果的利用。
