Seismic Hazard and Risk Analysis 9b - Fragility Functions

Understanding Fragility Functions and Damage States in Structural Analysis
This video delves into the quantification of failure probability using fragility functions, focusing on the log normal cumulative distribution function as the predominant model. It explains key parameters such as theta and beta, and their roles in defining the fragility function's location and shape. The discussion extends to multi-state damage evaluation, introducing ordered damage states from minor to complete damage, and illustrates how to compute probabilities for specific damage states. Practical examples from Hazus methodologies are also provided to contextualize these concepts.
This video is based on the book “Seismic Hazard and Risk Analysis” by Jack Baker, Brendon Bradley, and Peter Stafford (Cambridge University Press, 2021).
