PTI Level 1 and 2 exam
Group of closely spaced tendons placed together in a narrow strip usually along a
column line - CORRECT ANSWER-banded tendons
1000 lbs of force - CORRECT ANSWER-Kip
material used to protect against corrosion and reduce friction between prestressing
steel and sheathing - CORRECT ANSWER-PT coating
movement of wedges into the anchor cavity during the transfer of the prestressing force
to the anchorage, resulting of some loss of prestressing force - CORRECT ANSWER-
seating loss
Tendon in which prestressing steel is prevented from bonding to the concrete, and is
free to move relative to the concrete - CORRECT ANSWER-unbonded tendon
a device designed to connect two strands together - CORRECT ANSWER-coupler
a system which provides watertight connections at all stressing, intermediate and fixed
ends - CORRECT ANSWER-encapsulated system
increase in the length of the prestressing steel under the applied prestressing force -
CORRECT ANSWER-elongation
high strength steel wires twisted around a center wire - CORRECT ANSWER-strand
tendons usually short in length placed in specific locations, such as end bays, to
increase the uplift force at that location - CORRECT ANSWER-add tendons
A metal plate, which bears directly against the concrete and is part of an overall
anchorage system - CORRECT ANSWER-bearing plate
The friction caused by the unintended horizontal deviation of the tendon - CORRECT
ANSWER-wobble friction
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 -
CORRECT ANSWER-friction loss
The path a tendon follows in the concrete from end to end - CORRECT ANSWER-
profile
