Civil Engineering QUESTION #6642
Question 1
The term 'Bursting Tension' in prestressed concrete refers to:
  • Tensile stresses in the middle of the span
  • Transverse tensile stresses in the anchorage zone✔️
  • Stresses caused by over-jacking the tendon
  • Tension caused by temperature drop
Correct Answer Explanation
In post-tensioning, the concentrated force at the anchor spreads out into the concrete, creating transverse 'bursting' tensile stresses that require special reinforcement.
