| Abstract: |
Rajendra Setu (Rail Cum Road Mokama Bridge) was constructed in 1959 over river Ganga on NH-31 is of Span 3 x18,30m + 2 x 30,50m +14 x 121m + 2x30,5 m + 3x18,3m. The bridge was originally designed for BGML loading at railway level and 2-Lane Class A or 1-Lane Class AA at roadway level. East Central Railway intends to use the train for 25T – 2008 loading which is of higher loading standard than it was originally designed for and wanted to check the residual fatigue strength and to do the necessary modification for this purpose. This paper presents the steps followed for assessing the residual fatigue strength of the truss members and the railway & roadway floor system, i.e. the railway stringers & its connections and roadway stringers. The reason for the damage of the connection of the railway central stringers with rail cross are also assessed and presented in the paper along with its remedial measures. |
