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.
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.
