Description

This lecture covers the calculation of prestressing in concrete bridges, focusing on the effects of relaxation, shrinkage, and creep on prestressing losses. It also discusses examples of simple and curved beams with different cable configurations, as well as the design of cable anchoring devices. The instructor explains the advantages and disadvantages of various prestressing methods, such as using fixed hangers with suspension and different duct layouts for prestressing cables. The lecture emphasizes the importance of considering the interaction between different effects to accurately predict prestressing losses and optimize bridge design.
