What does "tensioning force" refer to in basic elongation calculations?

The term "tensioning force" in the context of basic elongation calculations specifically pertains to the load applied to the strand. In structural engineering and particularly in prestressing applications, tensioning force is the result of the force exerted on the steel strands or cables to create a desired level of stress within the concrete. This force is essential to ensure that the concrete can withstand the stresses imposed by external loads once the structure is in use.

When strands are tensioned, they experience elongation due to the applied load, making it crucial to understand how much force is being applied so that the structural integrity and performance of the material can be accurately assessed. Other aspects, such as the weight of concrete, environmental resistance, and initial setting time, although important in the overall context of construction and concrete performance, do not directly define what tensioning force means or why it is significant in elongation calculations.
