Prestressed concrete is used in a variety of structures, including bridges, buildings, and precast concrete products.
- Bridges: Prestressed concrete is commonly used in bridges because it allows for longer spans and reduces the amount of material needed. This makes it an ideal choice for bridges over rivers, highways, and railway lines.
- Buildings: Prestressed concrete is also used in high-rise buildings, parking garages, and other structures that require large, open spans. It allows for the use of thinner slabs and beams, which results in cost savings and increased floor space.
- Precast Concrete Products: Prestressed concrete is also used in the manufacturing of precast concrete products such as beams, slabs, and wall panels. These products are manufactured in a controlled environment and are then transported to the construction site for installation.
- Storage tanks: Prestressed concrete is also used to construct large storage tanks for water, oil, and other liquids. These tanks are designed to withstand the forces of the liquid and the pressure it exerts on the walls.
- Pavement: Prestressed concrete is also used in pavement construction, particularly in airport runways and heavy-duty highways. This is due to its ability to withstand the heavy loads and stresses caused by aircraft and heavy vehicles.
Sizes of Anchor Head in Prestressing
The size of the anchor head in prestressing & types of Anchor cones depends on several factors, including the size and type of the prestressed concrete member, the number and size of the tendons, and the design loads and stresses that the member will be subjected to.
Typically, anchor heads for prestressed concrete members are large, cast-in-place concrete blocks that are designed to transfer the prestressing force from the tendons to the concrete. The dimensions of the anchor head can vary depending on the size of the tendons and the amount of prestressing force that needs to be transferred.
For example, for a small precast concrete beam, the anchor head might be a rectangular block measuring around 30 cm x 50 cm x 80 cm. For a larger precast concrete beam or a prestressed concrete bridge girder, the anchor head might be much larger, measuring around 1 m x 1.5 m x 2 m.
It’s important to note that the size of the anchor head should be designed and verified by a structural engineer to ensure it can withstand the loads and stresses that the prestressed member will be subjected to and meet the safety factor and code requirement.
