Summary

In this subject, students learn theoretical background and practical information about probabilistic assessment of load-carrying structures. For that purpose, they should master the probability and structure reliability theories. Students will learn to express variability of input quantities in a stochastic (probabilistic), for instance, by histograms. The methods for the solution of probabilistic tasks will be introduced. the differences between probabilistic approaches and the applicable standards and procedures which are based on deterministic expression of input quantities (using a single value – a constant).
