With rapid population growth worldwide, urban centers are evolving into megacities. Megacities comprise of different infrastructures (e.g., buildings, bridges and lifelines) which are interlocked as a complex system. Megacities are vulnerable to different hazards. Between 1998-2017, direct economic losses summed approximately USD 2.9 trillion due to natural disasters worldwide [1]. This NSERC DG aims to continue improving the resiliency of megacities by expanding on the applicant's expertise of individual infrastructures under earthquake hazard towards regional level scale under multi-hazard loading conditions. The proposed research will focus on the following research tasks: Understanding the infrastructure behavior under multi-hazard loading conditions The behavior of infrastructures under multi-hazard loading conditions is complex. The research will focus on developing advanced numerical simulation and experimental testing platform for multi-hazard loading. Specifically, the developed platform will be able to predict the infrastructure response under fire and earthquake hazards. Evaluating the condition of the infrastructures on a megacity scale Infrastructure assessment is crucial for enhancing resiliency of a megacity. Current infrastructure assessment methods cannot be scaled to a regional level due to the complexity of the task and the sheer amount of resources required. This research will create an autonomous AI assessment platform to evaluate infrastructure conditions on a megacity scale. Improving the performance of the new and existing infrastructure performance There are many high-performance structural systems and retrofit schemes developed to improve infrastructure performance. However, these systems are usually designed for single hazards (Fire, Wind, Blast and Earthquake). There is no systematic procedure of designing structural systems and retrofit schemes for multi-hazard loading conditions. This research will focus on developing a novel design methodology to account for multi-hazard loading conditions. The research will also improve the performance of new and existing infrastructures by developing robust retrofit schemes and high-performance systems. The outcomes of this NSERC DG will significantly impact the field of structural engineering. The proposed research will allow infrastructures to be assessed under multi-hazard loading conditions. This will create novel structural systems and retrofit schemes which will improve the resiliency of individual infrastructures. Moreover, the developed autonomous AI assessment platform will allow infrastructure assessment in a regional scale. This will significantly change the infrastructure inspection industry where inefficient human inspection will be replaced. This NSERC DG will ensure that the infrastructures are protected from multi hazards, hence, enabling the sustainable growth of megacities in Canada and worldwide.

随着全球人口增长的迅速增长，城市中心正在变成大城市。大城市包括不同基础设施（例如，建筑物，桥梁和生命线），这些基础设施被互锁为复杂的系统。大城市容易受到不同危害的攻击。在1998年至2017年之间，由于全球自然灾害，直接经济损失约为2.9万亿美元[1]。该NSERC DG旨在通过扩大申请人在多危险加载条件下对区域级别范围内的各个基础设施的专业知识来继续提高MeGacities的弹性。拟议的研究将重点放在以下研究任务上：了解多危险加载条件下的基础设施行为。多危险荷载条件下的基础设施的行为很复杂。该研究将着重于开发高级数值模拟和实验测试平台，以进行多危险载荷。具体而言，开发的平台将能够预测火灾和地震危害下的基础设施响应。评估基础架构在大型量表基础设施评估中的状况对于提高大型的弹性至关重要。由于任务的复杂性和所需的资源量，当前的基础设施评估方法无法缩放到区域级别。这项研究将创建一个自主的AI评估平台，以评估基础架构条件。提高新的和现有的基础设施性能的性能，开发了许多高性能结构系统和改造方案，以改善基础设施绩效。但是，这些系统通常是针对单个危害（火，风，爆炸和地震）设计的。没有系统的程序设计结构系统和改造方案，以实现多危险载荷条件。这项研究将着重于开发一种新型的设计方法，以说明多危险的加载条件。这项研究还将通过开发强大的改造方案和高性能系统来改善新基础设施的性能。该NSERC DG的结果将显着影响结构工程领域。拟议的研究将允许在多危险加载条件下评估基础设施。这将创建新颖的结构系统和改造方案，以提高单个基础设施的弹性。此外，开发的自主AI评估平台将允许在区域范围内进行基础设施评估。这将大大改变基础设施检查行业，在该行业中将更换效率低下的人类检查。该NSERC DG将确保保护基础设施免受多种危害的保护，从而使加拿大和全球范围内的MeGacities的可持续增长。
