Question: What is the primary function of the sheathing in an unbonded post-tensioning tendon? Answer and Explanation: The sheathing provides corrosion protection for the steel tendon and prevents bonding between the tendon and the surrounding concrete. This allows the tendon to move freely during tensioning, ensuring the prestressing force is effectively transferred. Start reviewing with flashcards →
Question: At what point during installation should the initial inspection of tendons and anchorage components occur? Answer and Explanation: Initial inspection must happen upon delivery to the job site. This check ensures that materials are undamaged, correct specifications are met, and components are ready for proper installation. Identifying any issues early prevents problems later in the construction process. Explore our comprehensive study guide →
Question: When measuring tendon elongation during stressing operations, which reference point is typically used? Answer and Explanation: Elongation is measured as the difference between the tendon's initial length after being seated and its length after stressing. The reference point is usually the face of the jack or anchorage, from which the change in length is accurately recorded. Get key insights with flashcards →
Question: Which of the following best describes the purpose of "unbonded" in unbonded post-tensioning? Answer and Explanation: In unbonded post-tensioning, the steel tendons are coated with grease and encased in a plastic sheathing. There is no direct bond between the tendon and the concrete. The post-tensioning force is transferred entirely through the end anchorages, rather than through friction along the entire length of the tendon. Dive into the study guide →
