Student is able to directly or via some approximation method (especially Cornell reliabilioty index) evaluate failure probability. Student is also capable of using simulation methods Monte Carlo and Latin Hypercube Sampling. Student create finite element method model of concrete beam failure in software Atena. Student randomize the model in Sara studio.

Knowledge from Elasticity, Structural mechanic, Probability and Statistics calculus.

During lectures, standard model of theory explanation using the blackboard and projector is used. In the training course, students themselves solves tasks on a paper or with a help of computer. In the second part of training, there is an individual task to create a finite element model of failure of concrete beam in Atena software and randomization of the model.

Conditions to get credit are (i) active presence in training course (two absences are allowed) and (ii) creation and randomization of finite element method model of concrete beam failure.
Students are examined through individual oral questioning.
