Title: FATIGUE LIFE STUDY FOR A RAILROAD BASCULE BRIDGE
Accession Number: 00627143
Record Type: Component
Availability: Find a library where document is available Abstract: A fatigue study was undertaken for an 80-year-old drawbridge whose members receive cyclic loading from both draw-span movements and trains. Although the study was a modest effort, a significant amount of information was obtained. Fatigue loading was evaluated by drawing a traffic sample from the railroad's data base and modifying the results in accordance with historical records. Critical bridge members were identified using a three-dimensional linear elastic analysis, and their cyclic stresses were corroborated by the results of experimental work. Then the remaining fatigue life of these members was estimated. The results show that many of the members have a remaining fatigue life of substantial length.
