Introduction of Cantilever Bridge

What Is a Cantilever Bridge?

Type of Cantilever Bridges

• Balance Cantilever Bridges
• Continuous Cantilever Bridges

1. Balance Cantilever Bridges

2. Continuous Cantilever Bridges

Advantages of Cantilever Bridge

1. In this type of bridge, only one side support is provided in each cantilever.
2. The use of falsework is only required for the pier. Not required for other work.
3. In this type of bridge, the assembled parts of the suspended bridges can only be connected between two cantilever spans.
4. Bridge floors are easily built in such parts. Which maintains uniformity and ensures high quality.
5. Construction of multiple cantilever spans in these bridges can be started by reducing the time required.
6. There is no traffic obstruction under the bridge during its construction.
7. In areas with strong rock structures, anchor arms may be connected to the surrounding rock.
8. The span of a cantilever bridge is longer than a conventional beam.
9. This type of bridge can withstand the effects of thermal expansion and floor speed.
10. Supporting piers and supported highway styles add to the geometry of the bridge.

Disadvantage of Cantilever Bridge

1. This type of bridge is not suitable for areas with extremely bad climatic conditions.
2. These bridges generate high levels of stress during construction.
3. Compressive and tensile forces are generated in the cantilever bridge. A heavy structure is required for the stability of these forces.
4. Being part of a joint section in this type of bridge results in disability on the RCC floor.
5. Extensive analysis is required to prevent cantilever bridge elements and joint failure.
6. This type of bridge is complex for construction and maintenance due to its large foundation structures.
7. The cantilever arm of the cantilever bridge requires a large and strong support pier.
8. In this type of bridge, a truss bridge is connected between two cantilevers in a suspended span for a big span bridge.
9. This type of bridge is not recommended for use in earthquake-prone areas or low-rock stabilization areas.
10. These bridge depths can be dangerous or difficult to falsework for rocky valleys and flooded areas.
