Planned learning activities and teaching methods

Teaching methods depend on the type of course unit as specified in the article 7 of BUT Rules for Studies and Examinations. Education runs in the forms of lectures and trainings. Character of the lectures is based on definition of basic principles, problems and methodology. In the trainings the main subject matters are trained on individually defined projects (examples).

Assesment methods and criteria linked to learning outcomes

To gain the credit, the students should calculate technical tasks defined individually. The students are obliged to consult the task continuously in the given terms and submit it to the fixed date. The presences in training lessons are checked. An exam consists both of the written part and the theoretical part. To pass the exam successfully, both parts should be accomplished.

Course curriculum

1. Modelling of cross-section behaviour of concrete members, linear and non-linear analysis. General formulation of the problem as physically non-linear task.
2. Solution of the conditions of equilibrium. Iterative methods. Control of loadd-bearing capacity.
3. Non-linear material models of concrete and reinforced concrete.
4. Cracks, cracks localization, fracture energy, modelling of concrete in tension.
5. Plane state of stress, concrete crushing. Methods of solution of non-linear equations system.
6. Methods of non-linear task solution: layered, integral.
7. Non-linear modelling of flat concrete structures.
8. Non-linear analysis of prestressed concrete sections. Optimisation of reinforcement design into a section.
9. Non-linear material models of concrete and reinforced concrete in some comercial software of FEM systems.
