What is composite bridge deck?

What is composite bridge deck?

‘Composite’ means that the steel structure of a bridge is fixed to the concrete structure of the deck so that the steel and concrete act together, so reducing deflections and increasing strength. The concrete is good in compression, while the steel is good in tension and compression.

What is decking in bridge construction?

A deck is the surface of a bridge. A concrete deck may be an integral part of the bridge structure (T-beam or double tee structure) or it may be supported with I-beams or steel girders. When a bridge deck is installed in a through truss, it is sometimes called a floor system.

What is FRP deck?

FRP deck panels are used as an alternative to cast-in-place concrete decks. They provide a driving surface for traffic. The panels are designed to interlock with male-female shear keys. Another option for connecting the panels is the use of high-quality epoxy adhesives.

What is the main problem of bridge deck?

Bridge decks are vulnerable, subject to attack by water and chloride that can lead to deterioration and issues with longevity and durability of the bridge decks. The installation of an effective waterproofing membrane is therefore an essential part of bridge deck system in addition to the drainage system.

How thick should a bridge deck be?

1. Thickness. The thickness of reinforced concrete decks shall typically be 8 in but not less than 7½ in for all girder-type bridges.

What is FRP bridge?

One of the most promising group of new material in bridge design is fiber-reinforced polymer (FRP). FRPs are composite materials that consist of a polymer matrix reinforced with fibers. The fibers can be glass, carbon, basalt, or aramid, although other fibers such as paper, wood, or plant fibers have also been used.

How much does cost to build a composite deck?

Using composite to build a 10’ x 10’ deck can cost between $1,983 and $4,293. If you were to go a bit bigger and build a 20’ x 18’ deck: If that deck had a height of 8’2” and ran a total of 339 square feet, pressure-treated pine would be your least-expensive option for materials at $3,062.
