Description
Strength of corroded galvanized bridge wires were studied in this paper. Galvanized wires were wrapped with wet gauze and kept at high temperature, producing corroded galvanized specimens in different corrosion levels. Actual tensile strength of the corroded wires did not depend on the corrosion level. On the other hand, elongation and torsional strength decreased sharply after the zinc layer consumed and the steel started corrosion. It was estimated that this deterioration was caused by the surface roughness due to corrosion. This was verified by the tests which showed that elongation was recovered after the surface roughness of corrosion was smoothed. Volume of hydrogen absorbed in the corrode wires was measured, indicating that it did not reach a level to cause embrittlement.
