What Is a Cable-Stayed Bridge?
A cable-stayed bridge, also known as a cable-stayed bridge, is a bridge that draws the main beam directly on the bridge tower with many cables. Structural system. It can be regarded as a multi-span elastically supported continuous beam with a cable instead of a supporting pier. It can reduce the bending moment in the beam, reduce the building height, reduce the structural weight, and save materials. The cable-stayed bridge is mainly composed of a pylon, a main beam and a stay cable.
- Cable stayed bridge as a cable system,
- The cable-stayed bridge structure is a higher-order statically indeterminate structure in mechanics, and it is the most complicated structure in all bridge types. Due to the differences in cable forces and construction methods, the final state of the bridge will be significantly different. Therefore, in the force analysis of the cable-stayed bridge structure, the first task is to determine the reasonable bridge formation state is reasonable, so that the bridge structure is uniformly stressed, and then determine the reasonable construction state.
- 1.Overall modeling
- It can be seen from the figure that the vertical curve of the cable-stayed bridge has a great influence on the force of the main beam. Therefore, in the modeling of the cable-stayed bridge, the calculation axis of the main beam must be established according to the vertical curve.
- The main load on the bridge is not the car or train on it, but its own weight, mainly the main beam. Take one
- As a cable system, a cable-stayed bridge has a greater spanning capacity than a beam bridge, and is the main type of a long-span bridge.
- For example, Wuhan Second Yangtze River Bridge and Baishazhou Yangtze River Bridge are both reinforced concrete double tower and double cable plane cable-stayed bridges. The modern cable-stayed bridge can be traced back to the Strönsund bridge built in Sweden in 1956, with a main span of 182.6 meters. After half a century, the cable-stayed bridge technology has achieved unprecedented development. There are more than 200 cable-stayed bridges with a main span of 200 meters or more in the world, of which more than 40 have a span of more than 400 meters. Especially since the 1990s, the famous cable-stayed bridges built in the world are: Normandy cable-stayed bridge in France (main span 856 meters), steel box girder cable-stayed bridge in Nanjing Bridge of Nanjing Yangtze River Second Bridge (main span 628 meters), The Dodoro Bridge (the main span of 890 meters), the largest span in the world at that time, was completed in Japan in 1999.
- China has built more than 100 cable-stayed bridges of various types, of which 52 have a span of more than 200 meters. At the end of the 1980s, based on the experience of the Canadian Anasis Bridge, China completed the Shanghai Nanpu Bridge in 1991 (combined cable-stayed bridge with a main span of 423 meters), creating a large span of 400 meters and above in China The first of cable-stayed bridges. China has become the country with the most cable-stayed bridges.
- Cable-stayed bridges are one of the most popular types of long-span bridges in China. There are more than 30 cable-stayed bridges completed or under construction so far, second only to Germany and Japan, ranking third in the world. The number of long-span concrete cable-stayed bridges has ranked first in the world.
- In the mid-1950s, Sweden built the first modern cable-stayed bridge. For more than 40 years, the development of cable-stayed bridges has a strong momentum. China began to build concrete cable-stayed bridges in the mid-1970s. After the reform and opening up, the momentum of building cable-stayed bridges in China has been on the rise.
- Linjiangmen Bridge of Jilin City
- China has always been focusing on the development of concrete cable-stayed bridges. In recent years, China has begun to build hybrid steel-concrete cable-stayed bridges, such as the Shantou Shishi Bridge, with a main span of 518 meters. The Seven Yangtze River Bridge is a three-tower cable-stayed bridge with two main spans of 616 meters
- Steel box cable-stayed bridges, such as the Nanjing Bridge of the Second Nanjing Yangtze River Bridge, have a main span of 628 meters; Wuhan Junshan Yangtze River Bridge has a main span of 460 meters. The Nanpu (423m main span) and Yangpu (602m main span) bridges built in Shanghai in previous years are cable-stayed bridges with a combination of steel and concrete. The main span of Wuhan Yangsi Port Yangtze River Bridge will reach 1700 meters.
- The main girder forms of cable-stayed bridges in China: concrete is box-type, plate-type, and side-box-type; steel beams are mainly orthotropic steel boxes, and side-box-type.
- Cable stayed bridge
- Famous cable-stayed bridges built in the world are: Russia Island Bridge (1104m main span), Sutong Yangtze River Bridge (1088m main span), and Dodoro Bridge, the world's largest span built in 1999 (890m main span) . So far, more than 100 cable-stayed bridges of various types have been built in China, of which more than 50 have a span of more than 200 meters. Created a precedent for the construction of long-span cable-stayed bridges over 400 meters in China. China has become the country with the most cable-stayed bridges. On the list of the world's top 10 famous cable-stayed bridges, there are 8 in China, especially the Sutong Yangtze River Bridge with a main span of 1088 meters, which is the second span of the world s cable-stayed bridges.
