Abstract : Over 40 percent of inland navigation structures are more than 50 years old and demands for rehabilitation of these structures are increasing. Reliability assessments are used to assess the reliability of structures in their current conditions, to estimate the remaining service life of structures, and to provide a consistent method for prioritizing rehabilitation expenditures. Factors affecting the structures were identified and examined. The finite element method was found to be the best technique for assessing lateral soil displacement profiles for input into the Reese and Wang pile group analysis method. Techniques used for reliability analyses were introduced. The reliability index is used as a relative measure of reliability of a structure to perform in an acceptable manner. A reliability assessment of a navigation structure was demonstrated by an example problem.
