Prestress losses in a prestressed concrete member include:
Choose the correct answer
Elastic shortening, creep, shrinkage, relaxation (for pre-tensioned)
Only friction and anchorage slip (for post-tensioned)
Elastic shortening, creep, shrinkage, relaxation, friction, anchorage slip — which ones apply depends on pretension/post-tension
Only immediate losses
Correct Answer
C. Elastic shortening, creep, shrinkage, relaxation, friction, anchorage slip — which ones apply depends on pretension/post-tension
Why is this the answer?
Immediate losses: elastic shortening, friction (post only), anchorage slip (post only). Long-term losses: creep, shrinkage, relaxation. Total losses typically 15–25% of initial prestress.
