Syllabus

1. Effect of prestressing on bridge structures. Continuous box girder bridge – design, scheme of longitudinal and transversal section, load, structural model, structural solution in longitudinal direction – dead load. 2. Design of prestressing reinforcement, effects of prestressing. 3. Structural solution in longitudinal direction – varying load, combination of internal forces. 4. Serviceability limit state – stress and cracks limitation. Correction. 5. Ultimate limit state – bending moment. Drawing of prestressing cables. 6. Ultimate limit state – shear force and torsion. 7.
