Export a model to Autodesk Robot Structural Analysis

Before you export a Tekla Structural Designer model to Autodesk Robot Structural Analysis, read the limitations of Robot Export in the following paragraphs. Once you have read the limitations, you can proceed to the detailed instructions on how to export models from Tekla Structural Designer to Autodesk Robot Structural Analysis.

Limitations

The scope of the Robot Export is constrained by the limitations of the Robot Text File (STR) Format.

Note that:

  • The model exported is the one used for 1st order linear static analysis (see <Linear analysis of structures containing material non-linearity> to remove non-linearity from the exported model.)

  • 1D element springs are totally omitted from the export.

  • Elastic extensions cannot be defined in Robot. Therefore, additional 1D elements are created to preserve model connectivity.

  • The exported file will not group elements in any way. 1D elements will not be grouped as members (or columns, beams, etc). In addition, there will not be any grouping of faceted elements from a curved member. 2D elements will not be grouped into panels.

  • Section data is exported as analysis properties only. This means that no attempt is made to reference Robot library sections.

  • Material data is exported as analysis properties only. This means that no attempt is made to reference Robot library materials.

  • Loads in projection are converted to equivalent loads in Robot.

  • Robot will not import the material properties for timber from the STR file. When the file is opened in Robot, you can delete the G value and adjust the values manually after import.

  • It is not possible to define part-length distributed torsional loads in the STR file. Therefore, they are converted to equivalent full-length distributed torsional loads.

Instructions

  1. Create the model as usual.
  2. On the BIM Integration tab, click Robot Export.

    The Save As dialog opens.

  3. If necessary, change the name and location of the file.
  4. Click Save.
  5. Start Robot and open the file.
