Civil Engineering QUESTION #6632
Question 1
In prestressed concrete, 'Elastic Shortening' loss occurs in:
  • Post-tensioned members only
  • Pre-tensioned members only✔️
  • Both pre-tensioned and post-tensioned members
  • Neither; it is a reinforced concrete issue
Correct Answer Explanation
In pre-tensioning, as the tendons are cut and force is transferred, the concrete shortens immediately, causing loss. In post-tensioning, if all tendons are jacked simultaneously, there is no elastic shortening loss.
