Steel Cable-Stayed Bridge

No.46

  Cable-stayed bridge, also known as diagonal bridge, is a kind of bridge where the main beam is directly pulled on the bridge tower with many cables. It is a structural system composed of a pressurized tower, a strained cable and a bent beam body.

Description

Development, Achievements, and Possibilities

  Cable-stayed structures are the youngest, fastest-developing, and most promising bridge systems.

  Cable-stayed bridges are a subcategory of suspended structures. A cable-stayed bridge is similar to a suspension bridge in having towers and a deck-girder supported by cables; however, its diagonal cables transfer the vertical loads from the deck directly to the towers. Thus, the main deck-girder of a cable-stayed bridge works like a continuous beam on cable supports (more flexible than pier supports) with additional compression force throughout the deck. A cable-stayed bridge is also a prestressed system as its cable-stays are additionally tensioned to counterbalance a significant part of the vertical loads on the main deck-girder.

  The Strömsund Bridge in Sweden, completed in 1956 with a 182-meter (597-foot) main span, is considered the first modern cable-stayed bridge. For the following 65 years, cable-stayed bridges have seen a dramatic increase in both the number of new structures and in long-span achievements. By 1995, there were only 3 cable-stayed bridges with spans over 500 meters (1,640 feet); 25 years later, there are already 67 cable-stayed bridges with spans over 500 meters (including three over 1,000 meters or 3,280 feet). Another 29 with spans over 500 meters, with some over 800 meters (2,624 feet), are currently under construction.

  The efficient range of cable-stayed bridges is moving towards even longer spans. There is no other bridge structural system exhibiting such rapid development. Most cable-stayed bridges are visually beautiful, and some are among the most impressive of engineering achievements.





Product Description

       The cable-stayed bridge is mainly divided into three parts: main beam, cable tower and stay cable.

  The main beam generally adopts concrete structure, steel-concrete combination structure.

  Steel structure or steel and concrete mixed structure.

  Cable tower -it adopts concrete, steel-concrete combination or steel structure. Most of them are concrete structures.

  Stay cable - is made of high strength material (high strength steel wire or steel strand).

  Cables: The cables of a cable-stayed bridge are arranged in a fan-like pattern, extending from the towers to the bridge deck. The cables are made of high-strength steel and are anchored both at the towers and the bridge deck.

  The main beam is supported by the various points of the cable, and the continuous beam with multi-span elastic support is stressed, the internal bending moment of the beam is greatly reduced, and the size of the main beam is greatly reduced (the beam height is generally 1/50 ~ 1/200 of the span, or even smaller), which reduces the structural weight and greatly increases the crossing capacity of the bridge.

  The load transfer path of the cable-stayed bridge is: the two ends of the cable-stayed cable are respectively anchored on the main beam and the cable tower, and the dead load and vehicle load of the main beam are transferred to the cable tower, and then transmitted to the foundation through the cable tower.

The primary construction materials used in cable-stayed bridges are:


  For decks: reinforced or prestressed concrete, composite concrete-steel, or orthotropic steel decks;

  For deck-girders: beams of prestressed concrete or steel, box girders of prestressed concrete or steel, similar to those in modern suspension bridges;

  For towers: steel, reinforced or prestressed concrete, composite steel-concrete;

  For cables: high-strength steel wires, usually 270 grade (270 ksi, or 1,860 MPa), built from 7-wire, ⅜-inch (9.5 millimeters) strands per ASTM A886, other higher-grade steel wires, carbon fiber-reinforced polymers (CFRP), or composites. Prestressed concrete has been used in the past, but should be avoided as it has been proven unsafe on some failures such as the Morandi Bridge;

  For piers and foundations: reinforced concrete with or without piles depending on the soil.

  For long-span bridges, foundations on soft soils, or for bridges in high seismic areas, it is preferable to use predominantly steel structures to reduce the self-weight and the related earthquake forces.
