Prestressed Concrete Bridge Box Beams

Overview: Prestressed concrete box beams are composed of a hollow, rectangular cross-section with top and bottom flanges (known as the “box”) and vertical webs that connect the flanges. In prestressed concrete beams, the tensile weakness is remedied by applying a longitudinal compressive force creating internal compressive stresses which balances to a desired degree the tensile internal stresses. By so doing, the resulting internal stresses are mainly in compression. It is designed to handle heavy loads and provide a rigid, durable solution for various applications.
