That same year, the two men formed a bridge-building firm, Boody, Stone & Co., [10] which erected a large number of Howe truss bridges throughout New England. [8] Howe made additional improvements, and patented a second Howe truss design in 1846. [2] William Howe suffered a severe carriage accident and died on September 19, 1852.
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.
Truss bridge: A truss bridge is a bridge whose load-bearing superstructure is composed of a truss. This truss is a structure of connected elements forming triangular units. The connected elements (typically straight) may be stressed from tension, compression, or sometimes both in response to dynamic loads. Truss bridges are one of the oldest ...
The Waddell "A" Truss Bridge is standardized truss bridge design that was first patented in 1893 by prolific civil engineer John Alexander Low Waddell. The design provided a simple low-cost, high-strength solution for use by railroads across the United States and Empire of Japan for short spans of around 100 ft (30.5 m).
The Braga Bridge is a continuous truss bridge. It was the fourth longest span of this type when it was completed in 1966. This list of continuous bridge spans ranks the world's continuous truss bridges in two listings: The first is ranked by the length of main span (the longest length of unsupported roadway) and the second by the total length of continuous truss spans.
A bowstring truss is used on the oldest metal bridge in Virginia. Named for their shape, bowstring trusses were first used for arched truss bridges, often confused with tied-arch bridges. Thousands of bowstring trusses were used during World War II for holding up the curved roofs of aircraft hangars and other military buildings. Many variations ...
James Warren (1806–1908) was a British engineer who, around 1848 to 1907 (along with Willoughby Monzoni), patented the Warren-style truss bridge and girder design. This bridge design is mainly constructed by equilateral triangles which can carry both tension and compression.
