Evaluation of Safe-to-Fail Criteria for Coastal City Flooding
Publication: Construction Research Congress 2022
ABSTRACT
Global warming and climate change are extreme weather phenomena that lead to an exponential increase in destructive hurricanes causing severe flooding and critical damage to infrastructure systems in coastal cities. It is critical to explore and adopt innovative and effective resilient design strategies such as Safe-to-Fail for infrastructure systems to reduce disaster damages. This study aims to (1) collect the Safe-to-Fail strategies from literature and aggregate them; and (2) evaluate the aggregated Safe-to-Fail criteria to determine the most suitable criteria for reinforcing infrastructure resilience in coastal cities. This study utilized a multi-criterion decision-making tool Analytical Hierarchy Process (AHP), and the resulting weights indicate that the highest-ranked criterion is Redundancy (38.88%), followed by Resource efficiency (24.35%), Adaptability (24.21%), and Multifunctionality (12.55%). The findings of this research facilitate the implementation of Safe-to-Fail infrastructure systems to mitigate flood risks and support decision-makers in selecting resilient flood solution alternatives, particularly for coastal cities.
