Abstract :
A nondestructive evaluation technique has been developed to measure and analyze section loss due to corrosion for anchor rods used in guying steel transmission poles. The anchor guy system tested consists of a steel plate embedded in concrete connected to a steel rod buried in earth and attached to the guy wire from the pole. The method used was ultrasonics and specifically, the cylindrically guided wave technique. Field correlation of the method was verified by digging up and inspecting several rods. This approach has optimized the ultimate replacement and maintenance expense
