Is a cable-stayed bridge similar to a cantilever bridge?
Table of Contents
In cable-stayed bridges, the towers are the primary load-bearing structures that transmit the bridge loads to the ground. A cantilever approach is often used to support the bridge deck near the towers, but lengths further from them are supported by cables running directly to the towers.
What helps a cable-stayed bridge stay up?
cable-stayed bridge, bridge form in which the weight of the deck is supported by a number of nearly straight diagonal cables in tension running directly to one or more vertical towers. The towers transfer the cable forces to the foundations through vertical compression.
What is a spar on a bridge?
: a temporary bridge consisting of round timbers (such as tree trunks) lashed together and usually used for military purposes.
What are the parts of a cable-stayed bridge?
The main elements of a cable-stayed bridge are towers or pylons, deck girder(s), cable-stays, anchorages, and foundations. Tower and pylon are interchangeable terms; lighter, slender towers are often called pylons.
What are two main types of cable-stayed bridges?
In terms of cable arrangements, the most common type of cable stayed bridges are fan, harp, and semi fan bridges. Because of their large size and nonlinear structural be- haviour, the analysis of these types of bridges is more complicated than conventional bridges.
What is the name of the cable-stayed bridge?

Where is the longest cable-stayed bridge in the world?
The world’s longest cable-stayed bridge is the 2,680m (main span) JiaShao Bridge spanning the Qiantang River at the mouth of Hangzhou Bay in China. The bridge forms part of the 69.5km Jiaxing-Shaoxing River-crossing Expressway and consists of eight traffic lanes.
What is a cable-stayed bridge used for?
Cable-stayed bridge is a bridge similar to suspended bridge in that it has towers and a deck that is held by cables, but its cables hold the deck by connecting it directly to the towers instead via suspender cables. It usually carries pedestrians, bicycles, automobiles, trucks, and light rail.
Is a cable-stayed bridge a suspension bridge?
The difference lies in how the cables are connected to the towers. 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.
What are the disadvantages of a cable-stayed bridge?
List of the Cons of a Cable Stayed Bridge
- It can be an unstable design in certain environments.
- It has a maximum length.
- It can be a bridge design that is difficult to inspect.
- It can be susceptible to corrosion.
- It is only advantageous for short or medium distance needs.
How much weight can a cable-stayed bridge hold?
The maximum upward deflection is 5.8 ft (1.8 m). The maximum transverse deflection, at center span is 27.7 ft (8.4 m). Live load capacity per lineal foot is 4,000 lbs (1,814.4 kg).
What is the world longest cable-stayed bridge?
1. The Sutong Bridge arcs across a 6-kilometer-wide stretch of the mighty Yangtze River 50 miles upstream from Shanghai. Measuring 8.2 km overall, its main span is the current world record-holder for a cable-stayed bridge.
