The Warren truss is a prominent structural feature in hundreds of hastily constructed aircraft hangars in WW2. In the early parts of the war, the British and Canadian government formed an agreement known as the British Commonwealth Air Training Plan which used newly constructed airbases in Canada to train aircrew needed to sustain emerging air forces.
The fuselage was a modified Warren truss, with a curved lower chord or longeron and two additional, near vertical cross-members under the wing. The WJ 3's pilot sat without back support against the foremost of these on an exposed seat mounted on an extension of the lower longeron that also carried the controls.
Bridge No. 39 employs the Warren Pony Truss, a common truss type in the early 20th century. The Warren Truss is one of several variants on the basic kingpost structural system. It was patented in England by James Warren and Willoughby Monzani in 1848 and by Squire Whipple (inventor of the Whipple Truss) in 1849. The Warren consists of a series ...
It is a Warren deck truss designed by Ivan D. Merchant. Built in 1961, it has a length of 956 feet (291 m) in total, [ 1 ] [ 2 ] and a deck width of 30 feet (9.1 m). [ 2 ] The longest span is 371 feet (113 m).
[281] [308] As such, the Manhattan Bridge was the first suspension bridge in the world to use a lightly-webbed weight-saving Warren truss. [281] There are four stiffening trusses, two each flanking the tracks on the north and south sides of the bridge; these trusses measure 24 feet (7.3 m) [301] [302] or 26 feet (7.9 m) deep. [303]
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.
The footbridge is an intact representative example of a standard Warren Truss trestle footbridge with stairway, Hardie Board long plank timber deck and channel iron stair stringers. The barracks, although modified still demonstrates the key characteristics of standard accommodation for railway staff constructed during the early 20th Century. [3]
Completed c. 1912, the replacement Blackledge River Railroad Bridge is a riveted steel, double-intersection Warren deck truss. [2] The original granite stone abutments which supported the previous bridge was reported to be five feet lower, were integrated with the brownstone abutments of the rebuilt bridge.
