6. Sample heat and transport analysis problems.

7. Creep and shinkage prediction models for concrete.

8. Influence of temperature and humidity history on creep and shrinkage behaviour.

9. Creep and shrinkage prediction model B3. Material model for concrete and reinforcement.

10. Step-by-step method for styatic analysis of log-term loaded R/C structures

11. Linking transport analysis whith static analysis that account also for time

12. Sample analysis of the above model.

13. More advanced models-comparison of cross-sectional vs. material-point approach.
