This synthesis identifies and explains various inspection and maintenance techniques for bridge stay cable systems. It discusses both short- and long-term approaches. Topics covered included methods for inspections and assessments, including nondestructive testing and evaluation procedures; repair and retrofit; methods for control of cable vibrations, including rain-wind vibrations; stay cable fatigue and failure; effectiveness of various inspection and repair methods; limitations of available technologies; and trends and recommendations for future study. This synthesis effort was based on a comprehensive review of domestic and international literature on the inspection, repair, testing, and design of stay cable. On-line sources of information as well as engineering databases were examined. A questionnaire was distributed to all state and provincial departments of transportation in the United States and Canada to determine current state of the practice. Also, contacts were made with a number of knowledgeable individuals for information. Additional information was gathered from the examination of test reports and condition assessments from inspection of cable-stayed bridges, a review of a limited number of maintenance and inspection manuals for cable-stayed bridges, and a patent search using the U.S. Patent and Trademark Office database.
