Resilience assessment framework for critical infrastructure in a multi-hazard environment: Case study on transport assets.
Sotirios Argyroudis,Sotirios Argyroudis,Stergios A. Mitoulis,Lorenzo Hofer,Mariano Angelo Zanini,Enrico Tubaldi,Dan M. Frangopol +6 more
TL;DR: A novel framework for the quantitative resilience assessment of critical infrastructure, subjected to multiple hazards is proposed, considering the vulnerability of the assets to hazard actions and the rapidity of the damage recovery, including the temporal variability of the hazards.
Journal ArticleDOI
Rapid seismic damage evaluation of bridge portfolios using machine learning techniques
TL;DR: A methodology for the rapid damage state assessment of bridges utilizing the capabilities of machine learning techniques is proposed and revealed that input parameters such as span length and reinforcement ratio in addition to the ground motion intensity parameter have a significant influence on the expected damage state.
Journal ArticleDOI
Long-term resilience and loss assessment of highway bridges under multiple natural hazards
TL;DR: In this article, the immediate damage of highway bridges caused by natural hazards can disrupt transportation systems, which can cause a significant role in maintaining safety and functionality of the society, as well as a significant loss of revenue.

Resilience and Sustainability of Civil Infrastructure: Toward a Unified Approach
TL;DR: In this paper, a detailed comparison of the studies dealing with either infrastructure sustainability or resilience presented in this paper leads to the conclusion that they have a vast number of similarities and common characteristics, such as they both combine structural analyses with social and economic aspects; they both rely on techniques for the life-cycle analysis and decision making; and both are in an early stage, where the academic world is trying to find the best way to promote the application of the scientific results among professional engineers and the industry.
