Curved box girder bridge is extensively used in metro rail bridges. It is vital to build bridge constructions with curved plans as horizontally curved alignments for railway bridges and urban interchanges are becoming more common.

The multicell box girder bridge is a popular choice of designers because of its large torsional stiffness. The skewness at the support line of bridges has a significant influence on distribution . Horizontally curved box girder bridges inherently exhibit complex torsional and distortional behavior as well as bending due to the initial curvature.Distortional warping and transverse bending normal stresses, two major stress components resulting from distortion, are generally limited to a specific level for efficient use of the cross section by installing adequate .

In horizontally curved steel box girder bridges, large relative displacements between box girders and individual girder rotations may occur during the deck pouring operation. Installing intermediate external cross-frames between box girders is perceived to be an effective means to control these displacements. However, it is imperative to .

There are two general types of horizontally curved steel bridges. The box or tub girder is able to resist significant torsion if its shape is maintained with adequate internal bracing. This type of bridge was initially popular for that reason. The earliest box girder bridges had closed box sections ~i.e., steel on four
