Assessment of Depth of Girder of Railway Bridge
Abstract: The depth of a railway bridge girder is primarily determined by the span of the girder. The load exertedon the girder by passing trains induces a bending tendency, which is counteracted by the girder'sthickness or depth. This structural depth is crucial in neutralizing the bending moments and ensuringthe stability and safety of the bridge. Furthermore, the calculated depth or thickness of the girder mustbe validated against permissible deflection limits to …
