Community Hazard Risk Tools: Structural Fragility and Vulnerability and System Reliabilility Mapping
18 April 2025
This webinar introduces methods to assess structural fragility and map system reliability at the community scale using real-world data and MBNpy, an open-source tool for system reliability analysis.
DescriptionIn 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. |

Dr. Ahsana Parammal Vatteri
University College London
Dr Ahana Parammal Vatteri is a post-doctoral research fellow at the UNESCO Chair, where she focuses on developing tools for disaster resilience of integrated systems, particularly the application of Bayesian Networks and Agent-based modelling for system resilience problems. She focuses on confined masonry typology of buildings, especially school buildings and the resilience of education and associated critical infrastructure. She also works as a research fellow in Multi-hazard Resilience of Infrastructure Systems on the Horizon Europe project ‘MEDiate’, where she contributes to structural vulnerability assessment of buildings exposed to multiple hazards. Her engagements also include consultancy projects on seismic-safety assessment of schools, post-earthquake reconnaissance missions, taxonomy development for confined masonry school buildings (GPSS project for the World Bank), and delivering capacity building workshops and online courses.
