Steel Box Girder Bridge

The steel box girder bridge has excellent applicability to curved bridges owing to its large torsional rigidity. In addition, because the weight of the segments is smaller than that of concrete bridges, it also has many applications for medium-range bridges. However, when a bridge with a span greater than 70 m is constructed, the height of the steel box girder increases, which is disadvantageous for the manufacture and transportation of girders and for bridge construction. Therefore, improvements in the construction methods are required to facilitate construction. Therefore, a structural system of a double composite box girder bridge with an upper slab and composite high-strength concrete at the lower flange of the support of continuous span was proposed, and the structural performance was verified by finite element analysis and a static loading test of an actual specimen. It was confirmed that such a structure minimizes the height of the girder of continuous support by optimizing the sectional efficiency and also improves usability.
