PTI Level 1 & 2 Exam Frequently Tested Actual Questions and
Answers
Question 1.
1. According to PTI Specifications, what is the allowable tolerance for the measurement of
elongations in an elevated (structural) slab? a. ±5% b. ±7% c. ±10% d. It doesn't matter
as long as the tendons were stressed to the correct gauge pressure.
Correct Answer: b. ±7%
Question 2.
2. The recommended space, "Y" between tendon bundles in a beam is. a. 4in. b. 1.5 in. c. 1
in. d. 0.5.
Correct Answer: b. 1.5 in.
Question 3.
3. What is the minimum number of integrity tendons required in each direction over
columns in a flat slab? a. One b. Two c. Three d. There is no minimum requirement.
Correct Answer: b. Two
Question 4.
4. In an encapsulated system, how much bare strands is acceptable behind stressing
anchorage? a. None b. ½" maximum c. 6" maximum d. It does not matter.
Correct Answer: a. None
Question 5.
5. Longitudinal cracking of wedges may occur and is acceptable as a result of wedges
moving to their final wedge set position. a. True b. False
Correct Answer: a. True
, Question 6.
6. What should be done when the beam stirrup spacing does not match the PT support bar
spacing? a. Move the support bar to the nearest stirrup location and adjust the vertical
height so that a smooth tendon profile is maintained, add additional support bars at other
stirrup locations if needed so a maximum allowable support spacing is not exceeded. b.
Change the spacing of the beam stirrup to match the support bar spacing. c. Do not
proceed with installation until further instructions are received. d. None of the above.
Correct Answer: a. Move the support bar to the nearest stirrup location and
adjust the vertical height so that a smooth tendon profile is maintained, add
additional support bars at other stirrup locations if needed so a maximum
allowable support spacing is not exceeded.
Question 7.
7. When installing tendons in a narrow joist: a. It is important to avoid excessive wobble in
tendons that could lead to concrete blowouts. b. Tendon placement is not critical since
there is only one tendon in each joist. c. It is important to check for any reverse curvature
in a tendon profile to avoid problems. d. Both A and C.
Correct Answer: a. It is important to avoid excessive wobble in tendons that
could lead to concrete blowouts.
Question 8.
8. Of the following, what is the most important thing a contractor must do when field
installing a fixed-end anchor? a. Firmly hammer the wedges into the back of the anchor. b.
Grease the wedges before installing them in the anchor to reduce friction. c. Stress the
anchor to the full required jacking force. d. None of the above.
Correct Answer: d. None of the above.
Question 9.
9. The hydraulic pump can be interchanged without re-calibrating the stressing
equipment. a. True b. False
Correct Answer: a. True
Question 10.
10. If elongations are out of tolerance: a. Report to the LDP and wait for further direction.
b. If elongations are low, continue stressing to a higher gauge pressure until the reported
elongation is attained. c. Cut off tendon tails during the same shift. d. A and B.
Correct Answer: a. Report to the LDP and wait for further direction.
