Description:

Steel Box Girder Bridge refers to a beam bridge whose main beam is in the form of a thin-wall closed section. Long hollow trusses made of steel or concrete are usually used as beams. This makes the bridge light and sturdy. Bridges constructed using this method are called Steel Box Girder Bridge.

Steel box girder bridges are commonly used for highway flyovers and for modern elevated structures of light rail transport. Although normally the steel box girder bridge is a form of beam bridge, box girders may also be used on cable-stayed bridges and other forms.

Construction

For steel box girders, the girders are normally fabricated off site and lifted into place by crane, with sections connected by bolting or welding. If a composite concrete bridge deck is used, it is often cast in-place using temporary falsework supported by the steel girder.Either form of bridge may also be installed using the technique of incremental launching. Under this method, gantry cranes are often used to place new segments onto the completed portions of the bridge until the bridge superstructure is completed.
