The orthotropic deck may be integral with or supported on a grid of deck framing members, such as transverse floor beams and longitudinal girders. All these various choices for the stiffening elements, e.g., ribs, floor beams and main girders, can be interchanged, resulting in a great variety of orthotropic panels.
In 1992, the concrete deck of the cantilever metal part was replaced by an orthotropic steel deck. Gutters to channel the corrosive runoff to the river appeared in 1994. The pressure exerted by the reinforced beams on the ends of the trimmers then required the reinforcement of the latter by steel rods under tension.
In the deck-type bridge, a wood, steel or reinforced concrete bridge deck is supported on top of two or more plate girders, and may act compositely with them. In the case of railroad bridges, the railroad ties themselves may form the bridge deck, or the deck may support ballast on which the track is laid.
The deck is flexible and lies on the main cables, which are anchored to the earth. Underspanned suspension bridge: an early 19th-century descendant of the simple suspension bridge. The deck is raised on posts above the main cables. Stressed ribbon bridge: a modern descendant of the simple suspension bridge. The deck lies on the main cables, but ...
The main towers of the cantilever section were fabricated off-site and moved to the bridge site in four sections. Work on the cantilever arms moved out in both directions from the tower, with the shoreward arm keeping slightly ahead of the center arm so that it would rest on a temporary support structure to stabilize the bridge.
The bridge deck was milled and a new surface was poured and the structural steel was painted in order to extend the life of the steel. Work finished in the fall of 2011, but restarted in 2012 for expansion-joint replacement.
Megan Liu, lead study author and science and policy manager at Toxic-Free Future, tells Yahoo Life that this was a “minor point” in the study. “We feel bad that this happened,” she adds.
Decks can also be covered by a canopy or pergola to control sunlight. Deck designs can be found in numerous books, do-it-yourself magazines, and websites, and from the USDA. [8] Typical construction is either of a post and beam architecture, or a cantilever construction. The post-and-beam construction relies on posts anchored to piers in the ...
