/. 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.
- Answer-✅b. ±7%
/.2. The recommended space, "Y" between tendon bundles in a beam is.
a. 4in.
b. 1.5 in.
c. 1 in.
d. 0.5. - Answer-✅b. 1.5 in.
/.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. - Answer-✅b. Two
/.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. - Answer-✅a. None
/.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 - Answer-✅a. True
/.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. - 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.
/.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. - Answer-✅a. It is important to avoid excessive wobble in tendons that
could lead to concrete blowouts.
/.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. - Answer-✅d. None of the above.
/.9. The hydraulic pump can be interchanged without re-calibrating the stressing
equipment.
a. True
b. False - Answer-✅a. True
/.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. - Answer-✅a. Report to the LDP and wait for further direction.
