Operative Lines Tendon Projection

Important

This function is only available for users of SOFiSTiK Analysis + Design with interface to SOFiSTiK FEA

Allows to define the projection of prestressing tendon ducts within slab elements. Corresponding to this definition, tendon elements are generated during the analysis of systems where the tendon projections are visible in the Revit view.

The following steps enable you to create a Tendon Projection:

1. Make sure at least one pre-stressing system is available in your project (for this, use SOFiSTiK Analysis Tab > Manage > Drop-down: Settings > SOFiSTiK Data Management)

2. Click on Create Tendon Projection

3. The ribbon Place Lines is started with the preset line style SOF_TendonProjection

4. If necessary, adjust the Placement Plane of the line to be in the plane of the slab element

5. Draw one or several lines

6. Click on a SOFiSTiK Tendon Projection line and use the SOFiSTiK Structural Properties panel to adjust the tendon’s settings

Tip

Tendon Projections are standard Revit Model Lines with a specific type. Use Revit functions to easily move, copy, adjust etc Tendon Projections in your model.

Definition of Tendon Projections

The SOFiSTiK Structural Properties panel allows you to adjust the tendon’s settings.

General

Prestressing System of choice and a specific name for the tendon (optional).

Geometry

During the tendon definition, you can choose between automatic and user defined layout. Depending on your choice, the following options are available for the tendon geometry:

• Automatic tendon layouts:

  Layout is defined by the overall settings for the Tendon Projection in SOFiSTiK Structural Properties, it is possible to (de-)activate individual Tendon Stations intersecting the projection. Stations are always interpreted as high points.

  List of available parameters:

  Parameter	Description
  Distance from top	Valid for points along axis where a Tendon Station intersects (see Stations below)
  Distance from bottom	Valid for all points between stations
  Straight length at top	Segment with curvature 0°
  Transition length	Horizontal distance between top and bottom points
  Stations	Sub-menu to (de-)activate which intersecting tendon stations are considered. Stations are always interpreted as high points.

  Note

  Start and end point are centered over the height of the slab. To change this, create a Tendon Station.

• User defined layouts

  Layout is defined by the individual settings for the Tendon Projection at each station in the respective sub-menu. It is possible to (de-)activate individual Tendon Stations intersecting the projection. Stations are either interpreted as high points or low points.

  List of available parameters:

  Parameter	Description
  Stations	Sub-menu to - (de-)activate which intersecting Tendon Stations are considered - define axis reference and distance - define inclination and straight lengths to either side of the station

Construction Sequence

Define the construction stage for the prestressing application and grouting. For further information, see Tendon Manual.

Prestressing

Define other settings about the prestressing. For further information, see Tendon Manual.

Tip

Use multiselect to define settings for multiple tendons at once.

Note

When analyzing a Revit View where a tendon projection line is visible, a tendon will automatically be generated and calculated according to the settings made in Revit.
