Manage envelopes

You can use envelopes to view analysis results for multiple combinations simultaneously. When you do so, Tekla Structural Designer displays the maximum positive and negative values along each member from any combination included in the envelope.

Note: When using envelopes, note the following:
  • If you have defined patterned load combinations, you only need to include the base case pattern combination in the envelope. This way, Tekla Structural Designer automatically includes all pattern combinations derived from the base case in the envelope.

  • You can include gravity, lateral, and seismic combinations in the same envelope.

  • You should not include seismic RSA combinations in envelopes, as Tekla Structural Designer currently cannot display the results.

Create envelopes

  1. On the Load tab, click Envelope.

    The Loading dialog opens on the Envelopes page. This page displays all currently existing envelopes.

  2. Click Add.
  3. Name the envelope.
  4. On the left side pane of the Loading dialog box, click the name of the envelope.
