HURRICANE RETROFIT

Recent studies of four U.S. cable stayed bridges show that they are not deteriorating from corrosion. The cable technology used is an extension of the earlier developed cable technology for galvanized wires in structural-strand or locked-coil arrangements. The extension of small-cable technology to the manufacture of larger cables is usually the cause of many of the problems noted by investigators in 1988. These problems are discussed, and quality control problems in Canada are noted. The article describes the inspection of Sitka Harbor and Skagway bridges, and the Moore Creek Bridge in Alaska, as well as the Columbia River Bridge in Pasco, Washington. Comments are made on steel corrosion, and corrosion protection. Well designed and built, modern cable-stayed bridge cables have promise for long service. Also, modern cable stayed bridges are designed to permit removal of any cable at any time without interfering with the functional capacity of the bridge.
