Prof. Sergio Brena recently delivered a short course on “Design of Simple Prestressed Concrete Bridge Girders” at the Laboratory of Materials and Structural Models (Lanamme UCR), a part of the University of Costa Rica (UCR).
Brena was invited by researcher Ing. Rolando Castillo Barahona to discuss the advantages of prestressed beams, which are now used in many parts of the world.
These materials are particularly favored for their longevity; crucially, they are resilient to moisture, and so are less likely to become corroded in freezing climates, or in the humidity of places like Costa Rica.
UCR covered Brena's visit in this news article (in Spanish).
