Cable-stayed bridges with more than three spans involve significantly more challenging designs than do 2-span or 3-span structures. In a 2-span or 3-span cable-stayed bridge, the loads from the main spans are normally anchored back near the end abutments by stays in the end spans. For more spans, this is not the case and the bridge structure is ...
An extradosed bridge employs a structure that combines the main elements of both a prestressed box girder bridge and a cable-stayed bridge. [1] [2]: 85 [3] The name comes from the word extrados, the exterior or upper curve of an arch, and refers to how the "stay cables" on an extradosed bridge are not considered as such in the design, but are instead treated as external prestressing tendons ...
Category: Suspension bridges—For articles about specific suspension bridges. Cable-stayed bridge—Superficially similar to a suspension bridge, but cables from the towers directly support the roadway, rather than the road being suspended indirectly by additional cables from the main cables connecting two towers. Cable-stayed suspension bridge
Self-anchored suspension bridge: a modern descendant of the suspension bridge, combining elements of a cable-stayed bridge. The main cables are anchored to the ends of the decks. Taper suspension bridge: a 19th century variant of the suspension bridge where the suspenders pull at an angle to the ground, nearly tangent with the main cable
The longest suspension bridge in the world is the 4,608 m (15,118 ft) 1915 Çanakkale Bridge in Turkey. Cable-stayed bridge: Cable-stayed bridges, like suspension bridges, are held up by cables. However, in a cable-stayed bridge, less cable is required and the towers holding the cables are proportionately higher. [38]
The Millau Viaduct (French: Viaduc de Millau, IPA: [vja.dyk dÉ™ mi.jo]) is a multispan cable-stayed bridge completed in 2004 across the gorge valley of the Tarn near (west of) Millau in the Aveyron department in the Occitanie Region, in Southern France. The design team was led by engineer Michel Virlogeux and English architect Norman Foster.
A cantilever spar cable-stayed bridge is a modern variation of the cable-stayed bridge.This design has been pioneered by the structural engineer Santiago Calatrava in 1992 with the Puente del Alamillo in Seville, Spain.
The bridge is a Cantilever spar cable-stayed bridge, a type of Cable-stayed bridge in which cables are in a combination of radial and semi-harp arrangement; cables are spaced apart on the pylon, like the harp design, but connected to one point or a number of closely spaced points on the deck. [10]
