PTI LEVEL 1 & 2 EXAM

ACTUAL EXAM WITH CORRECT SOLUTIONS.

• According to PTI Specifications, what is the allowable

tolerance for the measurement of elongations in an elevated (structural) slab?

• ±5%
• ±7%
• ±10%
• It doesn't matter as long as the tendons were stressed to the

correct gauge pressure. - correct answer- b. ±7%

• The recommended space, "Y" between tendon bundles in a

beam is.

• 4in.
• 1.5 in.
• 1 in.
• 0.5. - correct answer- b. 1.5 in.

• What is the minimum number of integrity tendons required in

each direction over columns in a flat slab? 1 / 3

• | Page

• One
• Two
• Three
• There is no minimum requirement. - correct answer- b. Two

• In an encapsulated system, how much bare strands is

acceptable behind stressing anchorage?

• None
• ½" maximum
• 6" maximum
• It does not matter. - correct answer- a. None

• Longitudinal cracking of wedges may occur and is

acceptable as a result of wedges moving to their final wedge set position.

• True
• False - correct answer- a. True

• What should be done when the beam stirrup spacing does

not match the PT support bar spacing? 2 / 3

• | Page

• 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.

• Change the spacing of the beam stirrup to match the support

bar spacing.

• Do not proceed with installation until further instructions are

received.

• 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:

• It is important to avoid excessive wobble in tendons that

could lead to concrete blowouts.

• Tendon placement is not critical since there is only one

tendon in each joist.

• It is important to check for any reverse curvature in a tendon

profile to avoid problems.

• Both A and C. - correct answer- a. It is important to avoid

excessive wobble in tendons that could lead to concrete blowouts.
