Golden Gate Bridge/Bridge type
Golden Gate Bridge, suspension bridge spanning the Golden Gate in California to link San Francisco with Marin county to the north. Upon its completion in 1937, it was the tallest and longest suspension bridge in the world.
What materials are used for suspension bridges?
The towers of most suspension bridges are made of steel, although a few have been built of steel-reinforced concrete.
How is the Golden Gate Bridge suspended?
The Golden Gate Bridge is a suspension bridge, meaning it relies on cables and suspenders under tension along with towers under compression to cross a long distance without any intermediate supports.
Why is prestressed concrete used on bridges?
A properly engineered prestressed-concrete beam can span longer distances than a reinforced-concrete beam and it is thinner, lighter in weight, and uses less concrete without cracking or breaking.
What is precast concrete bridge?
Precast (Prestressed) concrete is used in various types of bridges where concrete is used such as Precast beam bridges, In situ balanced cantilever bridges, Precast segmental cantilever bridges, Incrementally launched bridges, Concrete arch foot bridges, Cable stayed bridges, etc., depending on the required length of …
Is the Golden Gate the longest suspension bridge?
Upon opening in May 1937, the Golden Gate Bridge was the longest suspension bridge in the world. The middle span between the 44,000-ton towers stretches 4,200 feet. Even today, few suspension bridges are as long, and none more spectacular.
How are suspension bridges supported?
Suspension bridges get their name from the fact that the roadway is suspended by cables from two tall towers. Most of the weight is supported by the two towers. They, in turn, pass the compression forces from the cables directly into the ground. Suspension bridges also have smaller cables called suspenders.
What do suspension bridges do?
A suspension bridge carries vertical loads through curved cables in tension. These loads are transferred both to the towers, which carry them by vertical compression to the ground, and to the anchorages, which must resist the inward and sometimes vertical pull of the cables.
How does a suspension bridge support the road?
As the name implies, suspension bridges, like the Golden Gate Bridge or Brooklyn Bridge, suspend the roadway by cables, ropes or chains from two tall towers. These towers support the majority of the weight as compression pushes down on the suspension bridge’s deck and then travels up the cables,…
What is the history of the Golden Gate Bridge?
In 1921, engineer Joseph B. Strauss submitted a design for a bridge that would cross the Golden Gate Strait — a hybrid bridge with a suspension span supported at each end by cantilever trusses.
How far can a suspension bridge span?
Suspension bridges can easily cross distances between 2,000 and 7,000 feet (610 and 2,134 meters), enabling them to span distances beyond the scope of other bridge designs.
What is the range of feasibility of cable stayed bridges?
There are some misconceptions re- garding the range of feasibility of cable stayed bridges. For example, the state- ment is often made that cable stayed bridges are suitable only for spans from 100 to 400 in (about 300 to 1300 ft).
