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.

A Warren truss. The Warren truss was patented in 1848 by James Warren and Willoughby Theobald Monzani, and consists of longitudinal members joined only by angled cross-members, forming alternately inverted equilateral triangle-shaped spaces along its length, ensuring that no individual strut, beam, or tie is subject to bending or torsional ...
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 new bridge is a six span Warren truss of through design and riveted steel construction. It is 950 feet 10 inches in length, and 19'-6" in width, originally had sidewalks on either side and, contains 534 tons of steel. The trusses are 22 ft high. The cost of this reconstruction was $96,410.65. [6]
Both bridges were of the Warren deck steel truss type, consisting of four 44-foot (13 m) steel spans on the approaches to each side with three (Queanbeyan River) and two (Molonglo River) spans of 90 feet (27 m) comprising the main bridge.
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.

There are two basic types of truss: The pitched truss, or common truss, is characterized by its triangular shape. It is most often used for roof construction. Some common trusses are named according to their "web configuration".
