In corrosion-accelerated failure, what is a direct effect on steel members?

Explanation:
When corrosion accelerates, the steel is eaten away from the surface, so the cross-sectional area available to carry load decreases. That loss of material directly reduces strength, and the small pits that form act as stress risers that easily initiate cracks under service or loading, which can then grow and lead to failure. So the direct effect is the reduction of cross-section plus potential crack initiation.
