Assessment of Probability of Failure of Building Structures in Uncertainty Conditions

When assessing a reliability of building structures, probabilistic models are used that have some random values (RV) as their input. The statistical analysis of these RV inevitably introduces some uncertainties in the assessments of their parameters. In this paper a novel method is given to assess the probability of failure (PoF) of building structures (BS) in the conditions of epistemic uncertainty of the initial data. Epistemic uncertainty is a systemic uncertainty that emerges due to insufficient knowledge about the processes being studied and substitution of them by some approximation models. The uncertainty is accounted for using the Bayesian analysis.
