      pitting corrosion is typical corrosion observed on coated steel member which exclusively carry oil, coal and iron ore. extensive survey on the effect of pitting corrosion on structural strength under a wide variety of loading conditions is necessary to clarify the relationship between pitting intensity and residual strength in detail. it is important to understand the effect of pitting corrosion on local strength of steel beam. a series of non-linear fe analyses has been conducted on structural models to investigate the effect of pitting corrosion on strength of web plates. the ultimate strength of a steel beam with pit corrosion and under a patch loading is governed by the dop (degree of pit corrosion intensity). the ultimate strength is found to be decreasing with increase in the degree of pitting intensity.
