Solid Slab Railway Bridge

Abstract

Different types of railway bridges are employed based on the span and width requirements. For smaller spans, solid slab bridges are utilized. In cases where a larger span is necessary, steel girder bridges become the preferred choice. When dealing with a wider river, trussed-type bridges are employed for railway applications. In trussed-type steel railway bridges, half of the load is supported by the trussed members, with only the remaining half imposed on the girder due to the passing train. Consequently, the depth of the girder in trussed-type railway bridges is halved compared to non-trussed bridge designs. This strategic distribution of load and structural design considerations contribute to the optimal performance of railway bridges across varying spans and widths. For smaller span the solid slab bridge is used: (1) For more span steel girders bridge is used. (2) For larger width of river trussed type (Railway bridges) are used. (3) In trussed type (Steel Railway Bridge) half of the load will be taken by members of trussed member & only half of the load is coming on girder due to moving train. (4) Hence in trussed type railway bridge depth of girder is half as compared to if no truss bridge are used.
