RSA seismic analysis

In order to run either a 1st or 2nd order seismic analysis on your model, see the following instructions.

Run a 1st order RSA seismic analysis

  1. On the Analyze ribbon, click Settings.

    The Analysis Settings dialog box opens.

  2. In the dialog box, go to the 1st Order Seismic page.
  3. If necessary, adjust the analysis options.
  4. Click OK.
  5. On the Analyze tab, click 1st Order RSA Seismic.

    Tekla Structural Designer analyzes the model.

    At the end of the analysis process the Results View and the Results tab open to allow you review the analysis results graphically.

Run a 2nd order RSA seismic analysis

Note: While RSA analysis itself is always 1st order, in this analysis type the RSA results are enveloped around 2nd order static analysis results.
  1. On the Analyze ribbon, click Settings.

    The Analysis Settings dialog box opens.

  2. In the dialog box, go to the 1st Order Seismic page.
  3. If necessary, adjust the analysis options.
  4. Click OK.
  5. On the Analyze tab, click 2nd Order RSA Seismic.

    Tekla Structural Designer analyzes the model.

    At the end of the analysis process the Results View and the Results tab open to allow you review the analysis results graphically.

Run Analyze All (RSA)

  1. On the Analyze ribbon, click Settings.

    The Analysis Settings dialog box opens.

  2. In the dialog box, go to the 1st Order Seismic page.
  3. If necessary, adjust the analysis options.
  4. Click OK.
  5. On the Analyze tab, click Analyze All (RSA).

    Tekla Structural Designer analyzes the model.

    At the end of the analysis process the Results View and the Results tab open to allow you review the analysis results graphically.
