ABSTRACT: This report presents the results of the Federal Railroad Administration project DTFR DV-00-G-60019 (Tank Car Reliability Design and Analysis), carried out in the Department of Civil and Environmental Engineering and the Department of Mechanical and Industrial Engineering at the University of Illinois at Urbana-Champaign. The overall objective of the project was to propose and develop new and improved rational procedures for assessing the structural integrity of stub sill tank cars, in order to provide higher levels of assurance against the occurrence of structural failure of a car that could lead to an accident. This research specifically focuses on procedures for establishing safe inspection intervals to detect the presence of fatigue cracks in the stub sill assembly before they grow to critical size.
