Mell What is decking in bridge?
A deck is the surface of a bridge. A structural element of its superstructure, it may be constructed of concrete, steel, open grating, or wood. 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.
What is the truss structure above the roadway of a bridge called?
pony trusses
Truss bridges are described according to the arrangement of the trusses: deck trusses (below the roadway), pony trusses (above the roadway, but without overhead bracing), and through trusses (above the roadway, with overhead bracing).
What bridge designs are the strongest?
A truss bridge is the strongest kind of bridge. These beams are pinned in place rather than affixed rigidly so as to allow vibrations to pass through the interconnected triangles and spread the force evenly through the design.
What do you call the arch below a bridge?
Arches below the bridge are called spandrel-braced (cantilever) or Trussed deck arch. Arch bridges can also use suspension bridges where the arch is made from truss system (tied arch, or bowstring bridge). Spandrel – Spandrels are the almost triangular space between the main pillar of the bridge and decking.
What are the parts of the bridge?
The main components of a bridge are the foundation, substructure, and the superstructure. Each of these core areas have other parts within them. Piles and pile caps are constructed as the foundation of the bridge. The sub-structure includes piers and abutments, while the superstructure includes the girders, bearings and deck.
What kind of structure is a stone bridge made of?
Stone bridges use filled “closed” spandrels deck arches, while modern bridges made from metal use open spandrel deck arch configurations. Truss – Framework made by connecting triangles and other forms that share load and stress forces across its entire structure.
