PT Tendons: Limitations on curvature in Plan
PT Tendons: Limitations on curvature in Plan
(OP)
What kind of limitations, or what parts of the ACI code, dictate what kinds of horizontal curves and turns you can make with a continuous PT strand in plan?
Too sharp a turn would probably cause a huge horizontal PT force, but I can't find anything on this...
Thanks!

RE: PT Tendons: Limitations on curvature in Plan
Vertical deviations of tendons - 1/8" to 1/4".
Horizontal plane deviations which may be necessary to avoid opneings, ducts, chases, etc. should be have a radius of curvature of not less than 21 ft.
There is most likely a more current edition to this. Also, you might try the PCI website for more info:
