Suggestion for PTCShape component

The current PTCShape component is good for shape in single span beam.
But for multispan continious beam, there are several issues:

  1. Some tendons in multispan continious beam do not start at the start point of the beam, while in the PTCShape component, the start point is always the start point of the beam line.
  2. For curved tendon. most engineers use spline or Line+Arc method to describle the shape. You can find more infomation in Midas Civil’s website about Line+Arc method. “If Round is selected in Curve Type”. Tendon Profile
  3. The current PTCShape component only considers tendon having curves in vertical plane, while some tendons have curves in both vertical and horizontal planes, especially in cured bridge.

Thanks for your feedbacks!

  1. Am I wrong or is it actually possible to have a start/end point different from the end points of a beam? I jave tried with Grasshopper and it worked.

Thanks Marco
Could you share the GH file? I used this model femdesign-api/FemDesign.Examples/Grasshopper/Practical example - Post-tensioned cables.gh at master · strusoft/femdesign-api · GitHub
The start point of the tendon is the same as that of the beam

Sure!

Basically, the input line for PTC does not have to be the same as per the beam element. You can use a different line geometry as a subdomain on a beam line.

Hello,

I know PTC can be added to the Beam. Can PTC be added to the plate/shell in the GH as well?
