ON FATIGUE EVALUATION OF RIVETED CONNECTIONS IN RAILWAY TRUSS BRIDGES . DEVELOPMENTS IN STRUCTURAL ENGINEERING. PROCEEDINGS OF THE FORTH RAIL BRIDGE CENTENARY CONFERENCE, HERIOT-WATT UNIVERSITY, ENDINBURGH, SCOTLAND, AUGUST 21-23, 1990. VOLUMES 1 AND 2

This paper addresses the reduction in the fatigue life of the critical members of a typical steel truss railway bridge due to a proposed increase in traffic. The bridge, on the Union Pacific Railroad in Nevada, is on a proposed route for transportation of hazardous materials through the state of Nevada; upon approval the normal train traffic is expected to increase. A modified bridge structural analysis program was used to save member load histories caused by the passage of both steam and modern diesel trains. A fatigue model based on Miner's rule and stress category D for riveted connections was chosen to estimate the remaining fatigue life. Stress values in five members of the bridge exceeded the endurance limit of category D under train loading. Fatigue life of the critical members will be reduced due to the proposed increase in the train traffic. (Author/TRRL)
