Use #5 stirrups, except as noted, with a 4 in. minimum and a 12 in. maximum spacing. Do not use stirrups larger than #6. Use double stirrups if required spacing is less than 4 in. If torsional resistance is explicitly addressed in the design, ensure the stirrup detailing is consistent with AASHTO requirements.

Provide a minimum 5 ft. tangent length of tendon from the anchorage head before introducing any curvature. Determine minimum radius of curvature of duct based on published values from suppliers for individual duct sizes.

Use minimum duct spacing according to Article 5.9.5.1.

Provide elevation and plan views showing the profile of centerline of ducts.

Show location of critical section(s) (i.e. the location of maximum flexural demand). Provide the magnitude of the initial stress in each tendon after anchor set at the critical section(s). Provide the assumed, post-tensioning stress, long-term loss of each tendon at the critical section(s).

Provide the stressing and erection sequence on the plans, including form removal and girder placement. Define when the bottom cap forms can be removed, based on the construction sequence designed.

Include the following information on the cap detail sheets:

Assumed coefficient of friction and wobble coefficient for duct
Assumed anchor set
Assumed and maximum allowed eccentricity between duct and tendon
Assumed long term losses
Stressing and dead ends of tendon
Jacking force = 0.XX x $f_{pu}$
x $A_{ps}$
= yy kips; replace “XX”, “ $f_{pu}$
”, “ $A_{ps}$
”, and “yy” with the values used in design.
Include stressing sequence; including constraints on partial stressing

Provide alternate reinforcing steel details where a known conflict between duct and typical reinforcing steel will occur. Include notes indicating all other adjustments to reinforcing steel must be made as directed by the Engineer of Record.

Include notes indicating that post-tensioning system/stressing sequence shop drawings must be submitted, reviewed, and approved by the Engineer of Record.
