Cable Stayed Bridges: Inspection, Evaluation, and Rehabilitation

This paper discusses advances in evaluation, health monitoring, and rehabilitation of cable-stayed bridges and available methods. In the last two decades, the author has contributed extensively to advances in cable-stayed bridge evaluation, inspection, and health monitoring. Information gathered from evaluation of the strength and reliability of cable-stay systems for nearly 25 long-span bridges, and instrumentation, health monitoring, and inspection of more than 12 cable-stayed bridges in the United States and abroad has helped the formation of a unified approach for evaluation and problem solving of these aesthetic structures. A case study related to evaluation and rehabilitation of the Luling Bridge in Louisiana, for which the new approach has been implemented almost entirely, is also described. The bridge evaluation process and cable replacement design and its implementation contain unique aspects and are the first attempted in North America. The cable replacement design accommodated an extraordinary construction sequence to address constraints on space and traffic flow. The new cable system allows individual strand installation and tensioning and is expected to facilitate future inspections and replacement.
