Tendon Profile Equations
Tendon Profile Equations
(OP)
Is there a generic formula to generate the profile of post-tensioning tendons, which includes the parabola (low points) and reverse parabola (high points).
I am trying to generate a worksheet to compute the shear capacity of prestressed concrete beams. Equations require me to calculate the depth of tendons, decompressing moment etc. based on AS3600 or BS8110 formulae.

RE: Tendon Profile Equations
No, there is not a generic formula.
You can either do the math to create a parabola with reverse curves and all of the possible permutations of end conditions like I did for RAPT.
Or use a good product (like RAPT) that has already done it for you (as well as the calculations for shear capacity of prestressed beams to AS, BS, ACI, Indian and Eurocodes!).

I may produce pdf printouts for inspection but none as effective for production as the actual operative worksheets here posted.
I remember that ACI sold one book that had one old MSWORKS worksheet dealing with this matter as well.

It was one from FAGUNDO, try to contact the author.

Thank you much. Do you happen to have the references on which your worksheets are based?
