Abstract
Steel pile foundation systems need to perform over a bridge’s service life, making corrosion an important consideration in the design and upkeep of these systems. Iowa DOT pursued options to combat steel’s natural process of corrosion when exposed to moisture, oxygen, and soil properties. New research indicates that galvanized and painted galvanized steel pilings are highly corrosion-resistant. But another solution — increasing the the pile section size — allows for section loss from corrosion while still providing the required design strength. Considering the costs of steel and galvanizing practices, larger piles are the economical solution.
