Draw tendons or convert tendons from AutoCAD geometry with reference to shown structural lines.

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 must be selected. It is also possible to choose more than one structural line. The selected structural lines will be used as a reference for finding beam elements to be prestressed. After choosing the structural line, 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 individual tendons use the Modify Tendons command (tendon_on_beam_m_small).

Note

Combining 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.

General#

In addition to the name and the number, there are the following entries:

Load Case and Prestressing System

For each tendon a load case and a prestressing system must be defined.

Considered Groups

By default, all element groups are taken into account. By specifying group numbers, however, it can be determined that only certain groups (primary and secondary groups) should be taken into account. A detailed description of the available setting options can be found in the chapter ‘GRP – Group Control’ of the manual TENDON.

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.
