[0002] Curved steel box girder bridge is a steel box girder bridge designed with a curved shape. Compared with straight steel bridges, curved steel box girder bridges are more visually beautiful and can make bridge projects more artistic. Curved steel box girder bridges not only have the advantages of general steel box girder bridges, such as high structural strength and large bearing capacity, but also can achieve the beautiful appearance of the bridge through curved shape. Bridge structures with this design concept usually consider more aesthetic elements in the design, adding a unique style to the city's bridge landscape. Curved steel box girder bridges are widely used in urban construction and have become a beautiful landscape of the city.
