Civil Engineering QUESTION #6650
Question 1
What is the primary advantage of 'Post-tensioning' over 'Pre-tensioning' in bridge construction?
  • It requires less steel
  • It allows for curved tendon profiles and field assembly of segments✔️
  • It eliminates all prestress losses
  • It does not require end anchorages
Correct Answer Explanation
Post-tensioning is versatile, allowing tendons to be draped in specific shapes to counter load-induced moments and enabling the joining of precast segments on-site.
