Prestressing and Concrete Bridges

This lecture covers the dimensioning of hyperstatic systems in concrete bridges, including prestressing effects, support forces, and frictional forces. It discusses the verification of stress in steel, cracking, and long-term losses due to delayed effects and friction. The presentation also delves into the calculation of equivalent loads, anchoring forces, and hyperstatic moments of prestressing. Various graphical representations and numerical applications are used to illustrate the concepts.
