The research presented in this thesis investigates this universal problem plaguing owners of suspension bridges across the globe. It is well known that the leading issue associated with deterioration and aging of steel bridges is corrosion. In most cases, visual inspection of structural members has long been an adequate method for monitoring steel structures exposed to environmental conditions which lead to corrosion. In the case of suspension bridges, it is possible to visually inspect the deck and towers with minimal difficulty; however, visual inspection of the main cables is both difficult and expensive. It is not possible to visually inspect the entire volume of the cable in a practical, cost-effective way. For this reason the current solution is to perform an invasive inspection in accordance with the NCHRP-534, which attempts to maximize the probability of estimating the condition of the cable while minimizing effort and expenses. These issues have lead researchers to look for nondestructive methods of determining the condition of the cable. The methods discussed in this thesis include acoustic monitoring, embedded sensors, and magnetic inspection through the magnetic main flux method. In addition, the study sought to identify the best available procedures for protecting the cables of suspension bridges from corrosion. Dehumidification, a method of controlling the cable environment to prevent corrosion, was identified as a promising preservation technology and is compared to traditional protection strategies. This study includes laboratory research on corrosion monitoring through acoustic emission and has evaluated both the available monitoring and preservation strategies for suspension bridge main cables. The research was performed for the Ohio Department of Transportation, and the results will have a direct impact on the Anthony Wayne Bridge in Toledo, OH. In addition, the information contained within this document provides useful information for suspension bridge owners across the country. 2013 English text University of Toledo / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=toledo1384545329 http://rave.ohiolink.edu/etdc/view?acc_num=toledo1384545329 unrestricted This thesis or dissertation is protected by copyright: some rights reserved.
