Course contents:

1. Compund actions: the compund bending. 2. Compund actions: bending combined with axial force, cross sections which do not transmit tension. 3. Energetical measures used in the study of deformable body. 4. Energetical theories and principles. 5. Strenght theories. 6. Post-elastic actions: the properties of materials, the analysis of cross section in the post-elastic domain. 7. Post-elastic actions: the analysis of structures. 8. The buckling of bars under centric compression: types of equilibrium, Euler's formula. 9. Practical application of bars under centric compression. The influence of the shear force on the critical stress. 10. The buckling of bars with compound cross sections. 11. The lateral buckling of slender beams. Superior order theories. The second order analysis of beams under bending and centric compression. 12. Shock actions. 13. Variable actions and fatigue analysis. 14. Beams on elastic environment.

Teaching methods:

Lecture, discussions, case studies, practical applications.
