What cable sizes are commonly used in post-tensioning applications?

In post-tensioning applications, specific cable sizes are chosen based on the strength requirements and the capacity needed for the structure. A common practice involves the use of .5 inch and .6 inch cables, as they offer a good balance between tensile strength and the ability to fit within the concrete elements being reinforced.

Using these sizes ensures that the post-tensioning system is efficient in transferring forces, while also being manageable during installation. The .5 inch cable is a standard size that provides adequate tension and is widely used in various applications, while the .6 inch option can provide additional capacity and is also quite prevalent in more demanding projects.

In contrast, other sizes mentioned in the options do not align with industry standards for the most commonly used cables in post-tensioning, as larger diameters may not be necessary for standard applications, and smaller sizes may not achieve the required tensioning effect. Understanding the specific cable sizes and their applications helps ensure the safety and effectiveness of post-tensioning designs in construction.
