Abstract
Bridges are the structural components necessary for the efficient movement of trains and locomotives, as well as the crossing of water courses, such as streams, across earth embankments, as road embankments cannot obstruct the natural waterway. Bridges can take various forms, including arch, slab, and box. These can be made from a variety of materials, including masonry (brick, stone, etc.) or reinforced cement concrete. Since the bridge passes through the earthen embankment, it is subjected to the same traffic loads as the road and must therefore be designed to withstand these loads. The buffer depends on the rail profile at the location of the bridge. The structural design requires consideration of load cases (box vacant, full, surcharge loads, etc.) and factors such as live load, effective width, deceleration force, load dispersion through fill, impact factor, and earth pressure coefficient, among others. Referring to relevant IRCs is required. The structural elements must be designed for optimum bending moment and shear force resistance. This paper examines the Codesprovisions, considerations, and justifications for the aforementioned design aspects. Software or Computational methodologies can be utilised to analyse the box bridge. Therefore, it is essential to evaluate the efficacy of results obtained from both methods
