- The learning outcomes:
– In this online training course, the basic concepts of a forward probabilistic hazard and risk analysis are covered. Within framework, the attendees will get a first lesson about the concept of fragility and the underlying assumptions of fragility for a class of assets exposed to risk. These concepts are further explored related to empirical fragility assessment. It is explained, at an introductory level, how the Bayesian inference, generalized regression models, and Markov Chan Monte Carlo simulation methods can be used for fitting and selecting the most suitable fragility model, given the available data. The attendees will also get a first glimpse into derivation of vulnerability functions based on convolution of fragility and consequence functions. A special focus is on the treatment and propagation of uncertainties in the fragility model parameters because of limited number of available data.
– In the second part, a set of hands-on demos are shown. These demos aim to show the application of the above-mentioned concepts in derivation and visualization of the fragility and vulnerability curves, their statistics, and the related uncertainties. The students who finish this course will be able to derive empirical fragility curves and vulnerability curves based on available toolboxes in MATLAB and Python and open-access standalone codes and will be able to interpret the results. The exercises are delivered in MATLAB and Python.
