Summary

1. Principals of pre stressed concrete. Material characteristics. Tensioning. Production technology. 2. Pre stressing force in ultimate and serviceability limit state according to EC 2. 3. Initial pre-stressing force of elements with coherent pre-stressing reinforcement. 4. Idealized cross-section and its usage. 5. Changes of pre-stressing before tensioning. 6. Changes of pre-stressing after tensioning. 7. Pre-stressed elements in elastic phase, normal stress, principal stress and strain. 8. Pre-stressed elements in limit state. 9. Ultimate load bearing capacity for normal force and bending moment. 10. Ultimate load bearing capacity for shear force, torsion and concentrated load. 11. Serviceability limit state of stress limitation, crack limitation and strain/deflection limitation 12. Statically indifferent structures. Effect of creep and shrinkage. 13. Structures with incoherent pre-stressing reinforcement. 14. Utilization of pre-stressed concrete. Basic types of pre-stressed structures.
