What is the consequence of having an inaccurate gauging system in a stressing jack?

An inaccurate gauging system in a stressing jack can lead to potential structural failures because it may result in improperly tensioned strands. Tensioning strands is critical to achieving the required performance and safety levels in structures such as bridges, concrete slabs, and pre-stressed elements. If the tension is either too low or too high due to inaccurate readings, it can compromise the integrity of the structure, leading to issues such as cracking, deformation, or even catastrophic failure. Therefore, ensuring that the gauging system is accurate is vital for maintaining the structural health and safety of engineering projects.

In contrast, improved tension in the strands is reliant on accurate measurements; hence, that outcome is not guaranteed. Increased safety measures would be necessary at times of inconsistency, making that choice less appropriate as well. Lastly, claiming that there is no impact on overall quality overlooks the direct correlation between proper tensioning and structural performance.
