    Steel bridge structure

     · When a bridge deck is installed in a through truss, it is sometimes called a floor system. A suspended bridge deck will be suspended from the main structural elements on a suspension or arch bridge. On some bridges, such as a tied-arch or a cable-stayed, the deck is a primary structural element, carrying tension or compression to support the span.

    Advantages and Disadvantages of Structural Steel Structures

     · Disadvantages of Structural Steel Structures. Steel is an alloy of iron. This makes it susceptible to corrosion. This problem can be solved to some extent using anti-corrosion applications. It has high maintenance costs as it has to be painted to make it corrosion-resistant. There are extensive fireproofing costs involved as steel is not fireproof.
