Syllabus of lectures:

1. Basic idea of prestressed concrete, advantages and problems. Methods of prestressing - pre- and post- tensioning.

2. Material properties - concrete, prestressing steel, reinforcing steel. Technologz and durabilitz of structures.

3. Concept of prestress losses.

4. Formulation of design criteria for the design of prestressed concrete section at ultimate limit state (bending, shear).

5. Formulation of designcriteria for the design of prestressed concrete section at serviceability limit state (stress, cracks and deflection limitation). Degree of prestressing.

6. Anchorage zones.
