Post-Tension Cable Profiling
Post-Tension Cable Profiling
(OP)
Can anyone help me with the equation for profiling PT cables in Reverse Parabolic shape?
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

If adjacent spans are significantly different (with differing inflection points) sometimes a compound parabola is used.
Things to keep in mind: check with the PT supplier/manufacturer on the systems MINIMUM tendon radius/curvature, and adjust your inflection points to maintain such a minimum. The manufacturer will also have a minimum straight-length distance that is applicable behind the anchorages.
Is this an unbonded PT slab tendon system or a grouted multi-strand beam tendon? The latter typically require a bit more 'finessing', especially if it is a bridge structure.

There is no single equation to do it properly using defined radius of curvature for the curve. We do have a solution in our software but unfortunately I cannot give that to you as everyone else has paid for it!
