Description

This lecture covers the principles and types of prestressed concrete, including pre-tension and post-tension methods, interior and exterior prestressing, different types of prestressing, and the effects of prestressing on reinforced concrete. It also discusses the initial prestressing force, deformations, and the system composed by reinforced concrete and cables. The lecture further explores the forces between cables and reinforced concrete, losses of prestressing due to friction, and the interaction between relaxation, shrinkage, and creep effects. Examples of beams with eccentric cables are also presented.
