Syllabus

1. Reinforced concrete bridge: Design and review of load-bearing structure of a slab bridge, design of bridge, space arrangement, embedding into terrain, superstructure, supporting and equipment. 2. Load (permanent and variable load – vertical moving load), calculation of internal forces using simplified method (method of interaction width), combination of internal forces. 3. Dimensioning for ultimate limit state – material, covering and reinforcement design, analysis of bend and shear, design of transverse reinforcement, anchorage of reinforcement. 4. Evaluation for serviceability limit state – stress and cracks limitation, displacement limitation. 5. Drawings of layout and arrangement of reinforcement. 6. Bridge substructure: Design and checking of support – load-bearing capacity, stability, cantilever wing. 7. Bridge saet (bearing chair), breast wall. 8. Structural members enabling expansion of load-bearing bridge structure. Calculation of expansions, design of members, adjustment of members for different temperatures. 9. Bridge from longitudinal prestressed segments. Design, load, transversal interaction of girders, internal forces, dimensioning and reinforcing principles. 10. Final correction. 11. Design submission.
