A Bailey bridge is a type of portable, pre-fabricated, truss bridge. It was developed in 1940–1941 by the British for military use during the Second World War and saw extensive use by British, Canadian and American military engineering units. A Bailey bridge has the advantages of requiring no special tools or heavy equipment to assemble.
The Samuel-De Champlain Bridge, colloquially known as the Champlain Bridge, is a cable-stayed bridge design by architect Poul Ove Jensen and built to replace the original Champlain Bridge over the Saint Lawrence River in Quebec, between Nuns' Island in the borough of Verdun in Montreal and the suburban city of Brossard on the South Shore.
Diagram of double tee beam. A double tee or double-T beam is a load-bearing structure that resembles two T-beams connected to each other side by side. The strong bond of the flange (horizontal section) and the two webs (vertical members, also known as stems) creates a structure that is capable of withstanding high loads while having a long span.
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 standard also encompasses the structural design of bridge foundations [4] as well as the design and requirements of bridge bearings for both ordinary and moving bridges. [6] [7] In 2010, BS 5400 was superseded by the Structural Eurocodes for the design of new bridges. However, BS 5400 still serves as the foundation for assessment standards ...
The design proposed was an elevated viaduct consisting of reinforced concrete columns and precast concrete segment spans as seen in the illustration at right. The design criterion was that the new bridge should survive an 8.5 magnitude earthquake on any of several faults in the region (particularly the nearby San Andreas and Hayward faults).
Incremental launch bridge construction Incrementally-launched bridge construction Itz Valley Bridge near Coburg. Incremental launch is a method in civil engineering of building a complete bridge deck from one abutment of the bridge only, manufacturing the superstructure of the bridge by sections to the other side.
The narrow section at mid-span gives the bridge profile a slight arch shape making this design particularly useful when large headroom is required. The profile also makes the bridge more architecturally pleasing than a beam bridge. Rigid-frame design may be the most efficient bridge type for spans between 35 and 80 feet (11 and 24 m). [5]
