What are cable stays?

Cable stays are steel cables used in the construction of many modern bridges. They provide support to the deck of the bridge, helping to transfer the weight of the bridge and any moving loads to the towers or piers.

- Cable stays are typically made from high-tensile steel and are designed to be weather-resistant and corrosion-resistant. This ensures that they can withstand the harsh conditions that bridges often face, such as high winds, heavy snow, and salt water.

- Cable stays are tensioned to specific levels during the construction of the bridge, and this tension is maintained throughout the bridge's life. This ensures that the cables remain structurally sound and able to support the weight of the bridge.

- Cable stays are often arranged in a fan-like pattern, radiating out from the towers or piers of the bridge. This design helps to distribute the load of the bridge evenly across the cables and reduces the stress on any individual cable.

- Cable stays are a critical component of many modern bridges and help to make these bridges strong, durable, and aesthetically pleasing.

Examples of bridges that use cable stays include:

- Golden Gate Bridge in San Francisco, United States

- Brooklyn Bridge in New York City, United States

- Akashi Kaikyo Bridge in Japan

- Millau Viaduct in France

- Lupu Bridge in Shanghai, China
