Create an analysis model

Create an analysis model

There are several methods to create an analysis modelstructural model that is created from a physical model and used on the one hand for analyzing structural behavior and load bearing, and on the other hand for design

Analysis model can be viewed in Tekla Structures in a model view.

Analysis model that is made with Tekla Structures can be worked on in other analysis and design software or application.

in Tekla Structures.

You can create an analysis model that includes all parts and loads you have in a physical modelstructural model with a direct or indirect counterpart in the structure to be built

, or that only includes the selected parts and loads. You can also create a new analysis model by copying an existing one, or you can create a modal analysis model.

We recommend that you first only include columns in the analysis model, and check that the columns are aligned. Then add primary beams and other parts as needed.

Create an analysis model for all or selected objects

  1. On the Analysis & design tab, click A & D models to open the Analysis & Design Models dialog box.
  2. Click New to open the Analysis Model Properties dialog box.
  3. On the Analysis model tab, select the analysis applicationpart of Tekla Structures functionality that is developed in order to extend the capability of Tekla Structures but that is not included in the Tekla Structures installation

    you want to use from the Analysis application list.
  4. Enter a unique name for the analysis model.

    For example, you can use a name that describes the portion of the physical model you want to analyze.

  5. To make the analysis model more accurate, select an option for the following filters :
    • Analysis model filter
    • Bracing member filter
    • Secondary member filter
  6. Select an option for analysis model content. Whichever option you choose, you can easily add and remove objects later.
    • Selected parts and loads
    • Full model
    • Floor model by selected parts and loads
  7. If you selected Selected parts and loads or Floor model by selected parts and loads , select the parts and loads in the physical model.

    To select the objects, you can use Organizer categories , for example.

    Note that if you create an analysis model for selected objects and then use an analysis model filter to leave out more objects, you cannot revert to the originally selected objects, even if you remove the filtering.

  8. If needed, define other analysis model properties.

    For example, if you need to run a non-linear analysis, change the analysis method on the Analysis tab.

  9. Click OK to create the analysis model.

Create a modal analysis model

You can create modal analysis models of Tekla Structures models. In modal analysis models, resonant frequency and the associated pattern of structural deformation called mode shapes are determined, instead of performing stress analysis.

  1. If you want to create an analysis model for specific parts, select them in the model.
  2. On the Analysis & design tab, click A&D models.
  3. In the Analysis & Design Models dialog box, click New.
  4. In the Analysis Model Properties dialog box:
    1. Define the basic analysis model properties.
    2. On the Analysis tab, select Yes from the Modal analysis model list.
    3. Click OK.
  5. When needed, define modal masses for the analysis model.

Copy an analysis model

You can create copies of existing analysis models. You can then use the copies, for example, to create multiple calculations with different settings.

  1. On the Analysis & design tab, click A&D models.
  2. In the Analysis & Design Models dialog box:
    1. Select the analysis model to copy.
    2. Click Copy.

      Tekla Structures adds the new analysis model to the list with the name <original model name> - Copy.

  3. Modify the analysis model or analysis parts or their properties as needed.

Delete an analysis model

You can delete unnecessary analysis models.

  1. On the Analysis & design tab, click A&D models.
  2. In the Analysis & Design Models dialog box:
    1. Select an analysis model.
    2. Click Delete.
  3. Click Yes to confirm.
