In an era where interconnected infrastructure systems underpin societal resilience, understanding the transition from individual structural performance to system-level reliability is more crucial than ever. This two-day session offers a step-by-step walkthrough into the fundamentals and practicalities of assessing fragility and vulnerability of structures as well as system reliability mapping at the community scale. On Day 1, participants will be introduced to the technical foundations of fragility and vulnerability assessment at structural level. The session then moves toward network reliability, with an accompanying introduction to MBNpy (https://github.com/jieunbyun/mbnpy), an open-source Python package designed to apply Bayesian networks for system reliability analysis. On Day 2, participants will engage in hands-on exercises. The first session focuses on identifying structural typologies and fragility functions for school buildings using a real-world database from Cagayan de Oro, Philippines. The second session applies MBNpy to map the reliability of an interdependent transport-school system, demonstrating how structural vulnerabilities propagate through interconnected networks.
