When a bridge deck is installed in a through truss, it is sometimes called a floor system. [1] 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 ...
A truss bridge is a bridge whose load-bearing superstructure is composed of a truss, a structure of connected elements, usually forming triangular units.The connected elements, typically straight, may be stressed from tension, compression, or sometimes both in response to dynamic loads.
The Hart Bridge is a continuous, cantilevered truss bridge with an unusual design that includes a suspended road deck on the 332-metre (1,088 ft) main span and a through truss deck on the adjacent approach spans. Some notable continuous truss bridges, with main span lengths.
Truss bridge for a single-track railway, converted to pedestrian use and pipeline support. In this example the truss is a group of triangular units supporting the bridge. Typical detail of a steel truss, which is considered as a revolute joint Historical detail of a steel truss with an actual revolute joint
If the bridge deck is carried along the bottom of the truss (called a through truss) or if a lightweight lower chord is present, identification is made solely by the multiple diagonal members emanating from the end post tops. An Inverted Fink Truss has a bottom chord without a top chord.
A Howe truss is a truss bridge consisting of chords, verticals, and diagonals whose vertical members are in tension and whose diagonal members are in compression. The Howe truss was invented by William Howe in 1840, and was widely used as a bridge in the mid to late 1800s.
A girder bridge is a bridge that uses girders as the means of supporting its deck. [1] The two most common types of modern steel girder bridges are plate and box. [citation needed] The term "girder" is often used interchangeably with "beam" in reference to bridge design.
The Belfast truss is a cross between Town's lattice truss and the bowstring truss. It was developed in Ireland as a wide-span shallow rise roof truss for industrial structures. McTear & Co of Belfast, Ireland began fabricating these trusses in wood starting around 1866. By 1899, spans of 24 metres (79 ft) had been achieved, and in the 20th ...
