PTI Training Questions with Complete Solutions

PTI Training Questions with Complete Solutions Add Tendons - Correct Answer Tendons usually short in length placed in specific locations, such as end bays, to increase the uplift force at that location Back-up bars - Correct Answer Reinforcing steel used to control the tensile splitting forces in the concrete resulting from the concentrated anchor force developed by the stressed tendons. Banded Tendons - Correct Answer Group(s) of closely spaced tendons placed together in a narrow strip usually along a column line. Bearing Plate - Correct Answer A metal plate, which bears directly against the concrete and is part of an overall anchorage system. Coupler - Correct Answer A device designed to connect two strand ends together. Elongation - Correct Answer Increase in the length of the prestressing steel under the applied prestressing force. Encapsulated System - Correct Answer A system which provides watertight connections at all stressing, intermediate, and fixed ends, and provides a watertight enclosure of the wedge cavity and prestressing steel. Friction Loss - Correct Answer The loss of force in a tendon resulting from friction that occurs between the strand and sheathing due to the wobble and/or profile of the tendon, created during stressing. Jacking Force - Correct Answer The maximum temporary force exerted by the jack while stressing a tendon. Kip - Correct Answer 1000 pounds of force
