Along with the scale expansion of highway construction in China, various large-span and large-tonnage bridge structures are also applied. At present, a simple supported bridge with a large span mostly adopts a T-shaped section beam or a box-shaped section beam. The T-beam bridge formed by the T-beams has small transverse rigidity, poor torsion resistance and poor stability during installation, and is not suitable for being used in large span. Simple girder bridges of large span generally employ box girders. When the span is great, the weight of the concrete box girder is great, and difficulty is brought to pouring or erection. The combined steel box girder is formed by combining a steel box at the lower part and a concrete slab positioned on the upper flange plate and is connected through a shear connector. The characteristics of strong compression resistance of concrete and high tensile strength of steel are utilized, and the material characteristics are fully utilized. The steel box girder has strong torsion resistance and easy erection and construction, and is suitable for roads and urban bridges. With the rapid development of the steel industry and the steel structure technology in China, the number of steel structure bridges is continuously increased, and the characteristics of large span, long service life, large torsional rigidity of a box section, small section height and good integrity of the steel box girder structure enable the steel box girder structure to be widely applied in the design and construction processes of municipal and highway bridges, and the steel box girder structure becomes the first choice of a large-span girder form. In the field of bridge engineering, steel box girders are increasingly widely applied to meet the requirements of use functions and bearing capacity.
