Creates tendon geometry and assigned tendon by drawing or selecting an existing AutoCAD geometry.

Use existing AutoCAD objects such as lines, polylines, splines and arcs to create a tendon geometry or draw the geometry directly.

Before creating a tendon a structural line or geometric axis is required. It is also possible to choose more than one structural line. The tendon which will be created will be referenced to the structural line or the geometric axis. After choosing structural line or axis, it is possible to create tendons by:

  • Draw a tendon (first point - next point)

  • Select object

  • Pick lines or curves

  • Polygonal mode

  • Set working plan

To modify the tendon elements use the Modify Tendons command (Icon: icon_modify_tendon ).

Note

Merging Slab PT with Shell PT or Beam PT in a drawing is not recommended. Of course Shell PT and Beam PT can be mixed.

During the definition of the tendons geometry the properties are given via a dialog.

Prestressing#

Stressing forces are computed automatically considering stressing sequences, wedge slip, friction, wobble, etc. The user, however, can limit the max force/stress/factor of the tendon at individual points:

Prestressing: According to AASHTO

This option is conform to the chapter ‘PAAS – Prestressing limits according to AASHTO’ of the manual TENDON.

Prestressing: According to Eurocode

This option is conform to the chapter ‘PSIG – Prestressing limits according to Eurocode’ of the manual TENDON. A description of the possibilities and the default values can be found there.

Prestressing: With Factors

This option is conform to the chapter ‘PFAC – Prestressing limits with factors’ of the manual TENDON.

Prestressing: Manual Prestressing

This option is conform to the chapter ‘PDEF – Manual prestressing’ of the manual TENDON.

Prestressing: Additional Data

This option is conform to the chapter ‘PDAT – Additional data of the prestressing’ of the manual TENDON.
