Abstract

An enclosure around bridge deck support steelwork provides an additional method of protecting the steel against corrosion. It reduces the rate of breakdown of the protective coatings to the steel by providing an environment of low corrosivity and reducing direct contact with atmospheric pollutants, leading to a reduction in maintenance. This Standard gives the requirements for evaluating and designing enclosures of bridges. It applies when designing enclosures for the structural steel elements below deck level of any type of bridge, whether as a method of reducing future maintenance costs or of improving access, or both. The Standard applies whether the enclosure is designed for an existing bridge or for a new structure.
