[0002] A steel box girder is a box-section beam made of welded or riveted steel plates. It has a high load-bearing capacity and good torsional resistance. It is usually composed of a top plate, a bottom plate and a web plate, forming a closed cavity inside. It can be used as part of the bridge deck or for arranging cables, pipes, etc. It is widely used in large-span bridges due to its good structural stability, light weight and fast construction speed.
