Development of a civil infrastructure resilience assessment framework and its application to a nuclear power plant

T. K. Singhal, O. Kwon, et al.

Explore the groundbreaking Civil Infrastructure Resilience Assessment Framework (CIRAF) developed by Tarun K. Singhal, Oh-Sung Kwon, Evan C. Bentz, and Constantin Christopoulos from the University of Toronto. This innovative framework uses a Bayesian Network approach to assess the seismic fragility and resilience of civil infrastructure systems, evaluating factors such as functionality loss and recovery time. Delve into its application through a case study of a nuclear power generation system and uncover effective upgrade strategies.

Abstract

This paper presents a Civil Infrastructure Resilience Assessment Framework (CIRAF) to assess the seismic fragility and resilience of civil infrastructure systems. CIRAF quantifies loss of functionality, recovery time, repair cost, and overall resilience using a Bayesian Network approach. A case study of a hypothetical nuclear power generation system demonstrates the framework's application and allows comparison of different upgrade strategies.
