Subject aims expressed by acquired skills and competences

Students are familiarized with probabilistic approach to the assessment of the safety, serviceability and durability with the aid of basic principles of theory of reliability and computers.

Teaching methods

Project work


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. The key feature of the probabilistic method is that it is possible to express variability of input quantities in a stochastic (probabilistic) form, for instance, by histograms. Unlike the applicable standards and procedures which are based on deterministic expression of input quantities (using a single value – a constant), the probabilistic methods provide more precise reliability assessment and improved safety for those who use the buildings and structures.
