Abstract
Coastal regions are exposed to both chronic and punctuated hazards, such as sea level rise and hurricane events, that can jeopardize entire coastal communities. Therefore, to effectively assess the risk and resilience of coastal communities subjected to multi-hazard environments, evaluation of the capacity of individual structures and infrastructure systems to withstand the different time-varying demands imposed in coastal settings is of paramount importance. This study proposes a comprehensive probabilistic framework for the design, risk and resilience assessment of coastal structures. The methodology also provides useful tools to inform decision-making, facilitate recovery efforts and improve resource allocation.Recorded Presentation from the vICCE (YouTube Link): https://youtu.be/8SI3Dw30yes
Highlights
Performance-based engineering approaches have been used to evaluate the performance of different structures during a natural hazard event for design, retrofit, and risk assessment purposes
Performance-based design methodologies have been implemented for specific types of coastal structures (Do et al 2016) by leveraging fragility functions and evaluation of mitigation strategies
This study proposes a comprehensive probabilistic framework for the design, risk and resilience assessment of coastal structures
Summary
Performance-based engineering approaches have been used to evaluate the performance of different structures during a natural hazard event for design, retrofit, and risk assessment purposes. The framework for performance-based engineering, originally proposed in the earthquake engineering community, has been recently extended to other types of natural hazards such as hurricanes, tsunamis and even multi-hazard scenarios (Attary et al 2017, Barbato et al 2013, McCullough and Kareem 2011) to perform probabilistic risk assessment of structures.
