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. -
ANS 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. - ANS b. 1.5 in.

,b. Two
c. Three
d. There is no minimum requirement. - ANS 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. - ANS 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 - ANS 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. - ANS 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. - ANS 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. - ANS d. None of the above.
9. The hydraulic pump can be interchanged without re-calibrating the stressing equipment.
a. True
b. False - ANS 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.
