Multi-hazard Vulnerability Assessment of Structures for Resilience Enhancement (MultiVERSE)

MultiVERSE旨在为民用基础设施开发一种创新的、强大的和协调的多灾害设计和评估方法，充分考虑相关的结构、技术、经济、环境、监管和社会文化（STEERS）因素。为了实现这一目标，MultiVERSE提出了一种新的基于性能的多灾害工程（PBME）框架（地震序列和地震海啸序列），用于对靠近欧洲构造活动区的沿海地区（如希腊、土耳其、意大利）的结构进行多灾害脆弱性评估。通过采用跨学科的决策方法，PBME框架解决了各种问题，从危害相互作用及其对结构性能的累积破坏影响，到有效增强弹性的民用基础设施设计和评估的预期损失。尽管该框架适用于所有建筑类型，但本项目侧重于钢筋混凝土（RC）建筑，因为它们在大多数多灾害脆弱的欧洲国家的建筑中占很大比例。该框架将应用于意大利的单个建筑和大型建筑组合，主管与当地利益相关者有着密切的联系，从而确保数据可用性、知识转移和研究对当地社区的实际影响。multiverse建立在主管和主办机构的概率灾难风险建模专业知识和研究员的RC地震设计和评估专业知识的基础上。PBME框架将通过为执业工程师和各种利益相关者在多灾害易发地区设计新结构和评估现有结构提供更好的指导，以及为灾前和灾后环境（例如，灾后建筑标签和最佳修复或改造技术选择和设计）提供面向实践的最佳决策工具，促进减少多灾害风险。

MultiVERSE aims to develop an innovative, robust and harmonised multi-hazard design and assessment methodology for civil infrastructures with full consideration of relevant structural, technological, economic, environmental, regulatory, and sociocultural (STEERS) factors. To achieve this aim, MultiVERSE proposes a novel performance-based multi-hazard engineering (PBME) framework (earthquake sequences and earthquake-tsunami sequences) for multi-hazard vulnerability assessment of structures in coastal regions close to tectonically active zones in Europe (e.g., Greece, Turkey, Italy). By adopting a cross-disciplinary decision-making methodology, the PBME framework addresses issues ranging from hazard interactions and their cumulative damaging effect on structural performance to the expected losses for efficient resilience-enhancing design and assessment of civil infrastructures. Although the framework is applicable to all construction types, this project focuses on reinforced concrete (RC) buildings because they represent a significant proportion of buildings in most multi-hazard-vulnerable European countries. The framework will be applied to individual buildings and a large-scale building portfolio in Italy, where the Supervisor has strong links with local stakeholders, thus ensuring data availability, knowledge transfer and actual impact of the research on local communities. MultiVERSEbuilds on the probabilistic catastrophe risk modelling expertise of the Supervisor and Host Institution and the RC seismic design and assessment expertise of the Fellow. The PBME framework will promote multi-hazard risk reduction by providing better guidance to practising engineers and various stakeholders for designing new structures and assessing existing structures in multi-hazard prone regions, and practice-oriented tools for optimal decision-making in pre- and post-disaster settings (e.g., post-event building tagging and optimal repair or retrofit technique selection and design).
