| Abstract | One portion of the Federal Railroad Administration's (FRA) Track Performance Improvement Program is the development of engineering and analytic techniques required for the design and maintenance of railroad track of increased integrity and safety. Under the program management of Transportation Systems Center (TSC), a part of this program is to predict the reliability of rail in track. A necessary requirement for development of these techniques is the ability to determine the stress and strain history of the rails in service. This is necessary to form a more comprehensive basis for a quantitative understanding of flaw initiation and growth. This report provides a comprehensive description of stresses in rail required for predicting reliability of rail in track structures. Contained is a description of stresses encountered in cracked and uncracked railroad rails at midrail stations and bolted joints as computed using analytical techniques developed in this program. |
