Project work

In this subject, students learn theoretical background and practical information about probabilistic calculations of civil engineering structures. For that purpose, they should master the probability and mathematical statistics 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 or probabilistic distribution.
