In the last years, prestressed concrete structures, particularly bridges, have been increasing in popularity in consequence of its versatility and the multiple advantages that they have in terms of durability, resistance and design. Inducing a state of tension and deformation, the prestressing technique improves the structural behavior, and with a low amount of steel cables allows obtaining a higher load carrying capacity. The advantages of dealing with prestressed elements extend to the possibility of reducing the dimensions of the transversal section and increasing the length of the spans between pillars. Nevertheless, the performance of prestressed structures depends on the prestressing level, related to the real state of its components, and this could be considered as a drawback which can lead into a brittle and catastrophic failure.
