Mell What do cables on bridges do?
In suspension bridges, the cables ride freely across the towers, transmitting the load to the anchorages at either end. In cable-stayed bridges, the cables are attached to the towers, which alone bear the load. In a radial pattern, cables extend from several points on the road to a single point at the top of the tower.
What is a main cable on a bridge?
The main cables, which are free to move on bearings in the towers, bear the load of the bridge deck. Before the deck is installed, the cables are under tension from their own weight. Along the main cables smaller cables or rods connect to the bridge deck, which is lifted in sections.
Why are cable stayed bridges strong?
The cable-stayed bridge can handle more pressure on a consistent basis compared to the suspension design, allowing the deck to have more resilience against wear and tear because there is greater rigidity in its construction.
Which is better suspension bridge or cable stayed bridge?
The symmetrical building of the road deck balances the load, eliminating the need for large ground anchorages. In short, cable-stayed bridges bear the road-deck weight differently, are faster to build and require less construction materials than suspension bridges.
How are cable stayed bridges used in construction?
Learn about this topic in these articles: construction. In bridge: Cable-stay Cable-stayed bridges carry the vertical main-span loads by nearly straight diagonal cables in tension. The towers transfer the cable forces to the foundations through vertical compression. The tensile forces in the cables also put the deck into horizontal compression.
What kind of wire is used for suspension bridges?
TechStar represents both Baosteel Ergang and Shanghai Pujiang Cable outside of China. Both of these companies are from Shanghai, China. The Wire is produced by Baosteel Ergang and Shanghai Pujiang produces the cables. Parallel wire is used as the main cable for all suspension bridges. The cable is erected in one of two ways.
What kind of compression does a cable stayed bridge use?
The towers transfer the cable forces to the foundations through vertical compression. The tensile forces in the cables also put the deck into horizontal compression. In bridge: Cable-stayed bridges Construction of cable-stayed bridges usually follows the cantilever method.
How are the cables attached to a bridge?
How Bridges Work. The cables attach to the roadway in various ways. For example, in a radial pattern, cables extend from several points on the road to a single point at the tower, like numerous fishing lines attached to a single pole. In a parallel pattern, the cables attach to both the roadway and the tower at several separate points.
