A Box Girder Bridge is a type of bridge where the main beams comprise girders in the shape of a hollow box. The box girder normally comprises either prestressed concrete, structural steel, or a composite of steel and reinforced concrete. The box is typically rectangular or trapezoidal in cross-section. Construction of these bridges involves either in-situ casting or prefabricating the box girder sections before placing them with the help of cranes or launching gantries. This method is widely used due to its inherent strength, which allows for long spans and the ability to withstand torsional forces. Applications of box girder bridges are diverse. They are commonly used for highway flyovers and as elevated structures for light rail transport. Due to their excellent high torsional stiffness, they are particularly beneficial in situations where the self-weight of the bridge needs to be minimized, such as in long-span bridges or cable-stayed bridges. The design of box girder bridges can vary, with some using multiple girders with a deck slab spanning transversely between the webs, while others may employ a single large box girder with the deck slab acting compositely with the top flange of the box. For more detailed information on the design and construction aspects of box girder bridges, resources like the Design Guide for Composite Box Girder Bridges by the Steel Construction Institute can be very helpful.
