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. Design of shearing reinforcement. 8. Design of reinforcement in transverse direction. 9. Correction. 10. Design and review of cross beam. 11. Drawing of passive reinforcement, technical report, completion. 12. Final correction. 13. Design submission. Credit.
