Cable-stayed bridge - Wikipedia, the free encyclopedia A self-anchored suspension bridge is similar in principle to the cable stayed type in that tension forces that prevent the deck from dropping are converted into compression forces vertically in the pylon and horizontally along the deck structure. Smaller cables or rods are then suspended on the main cable, and used to support the load of the roadbed, which is lifted in sections and attached to the suspender cables.

Cantilever spar cable-stayed bridge - Wikipedia, the free encyclopedia A cantilever spar cable-stayed bridge is a modern variation of the cable-stayed bridge. Cable-stayed bridge - The ancestor of this type In two of his designs the force distribution does not depend solely upon the cantilever action of the spar; the angle of the spar away from the bridge and the weight distribution in the spar serve to reduce the overturning forces applied to the footing of the spar. en.wikipedia.org /wiki/Cantilever_spar_cable-stayed_bridge   (181 words)

Cable Stayed Because the cable-stayed bridge is well-balanced, the terminal piers have little to do for the bridge except hold the ends in place and balance the live loads, which may be upward or downward, depending on the positions of the loads. The four anchorages of a suspension bridge have to withstand the tension of the four cable-ends, and are often massive constructions. The penalty for the sloping cables is the compression induced in the deck. www.brantacan.co.uk /cable_stayed.htm   (4514 words)

Georgia @ SouthEastRoads.com - U.S. Highway 17 To address the need for a higher structure, the new cable stay bridge was built, and the lift bridge limped along until March 23, 2003, when it was closed. Opened in 1956, the vertical lift bridge was mired with problems relating from mechanical failure and often had to be closed for repairs causing lengthy detours to the west for Brunswick bound traffic. That bridge fee mandated that the U.S. 17 mainline remained northwest of the city to Port Wentworth and the free Houlihan Bridge. www.southeastroads.com /us-017_ga.html   (1095 words)

Bridge Types - Cable Stayed For longer span cable-stayed bridges, careful studies must be made to guarantee the stability of the cables and the bridge in the wind. The unique properties of cables, and the structure as a whole, make the design of the bridge a very complex task. The fabrication of cable stay bridges is also relatively difficult. www.matsuo-bridge.co.jp /english/bridges/basics/cablestay.shtm   (359 words)

HistoryLink Essay:Cable-stayed bridge over Tacoma's Thea Foss Waterway opens on January 22, 1997. The cable-stayed bridge over the Thea Foss Waterway replaced the 1953 Blair Waterway drawbridge, which was then dismantled. The twin towers of the bridge were 180 feet tall and the two spans totaled 707 feet. It is one of only 13 such bridges in the nation and is part of a $165.3 million project that connects Interstate-5 to downtown Tacoma. www.historylink.org /essays/printer_friendly/index.cfm?file_id=5150   (285 words)
