    Structural analysis assumptions for Storm.

    • This Storm version lets you perform the static linear analysis.
    • You can perform the analysis for analytical model elements and entities.

      List of analytical model elements and entities

      • Structural Elements
        • Structural Floor and Wall
        • Structural Column
        • Structural Beam
        • Structural Bracing
        • Isolated Footing (analyzed as a fixed nodal support)
        • Wall Foundation (analyzed as a fixed linear support)
        • Foundation Slab (analyzed as a slab)
        • Curtain wall (analyzed as a cladding distributing loads)
      • Rigid links between Beam and Column
      • Boundary conditions (analyzed as supports)
      • Releases for Column, Beam and Bracing
      • Materials
      • Loads
      • Load Case and Case category
      • Load Combinations
      • Levels defining stories in Robot for analysis of results.
    • Surface elements of the analytical model, such as Structural Floor, Wall and Foundation Slab, are analyzed using the finite element mesh. The assumed maximum size of a mesh element depends on the analysis profile you selected. Selecting Draft reduces the analysis duration, providing coarse accuracy of results. Selecting Fine ensures more accurate results, however, it takes longer to complete the analysis.
    • If you create design options, only the Main Model option is included in the analysis.
    • Definition of Project Phases is ignored. Elements of the analytical model belonging to all phases are included in the analysis.
    • Sending the model for analysis to Storm you can automatically generate self-weight of the structure.
      NoteOnly the self-weight of the analytical model sent to Storm is included in the analysis. However, it may differ from the self-weight of the physical model in a Revit project (see Structural Analytical Model Overview).
    • Envelopes. When sending the model to Storm, predefined envelopes are added to the list of load cases and combinations defined in the Revit project, and included in analysis.

      List of Predefined Envelopes

      • ULS Combinations - Top envelope
      • ULS combinations - Bottom envelope
      • SLS combinations - Top envelope
      • SLS combinations - Bottom envelope
      • Simple load cases - Top envelope
      • Simple load cases - Bottom envelope.

      Predefined envelopes are presented in the Results dialog on the Load case list.

    • If you add a new load combination, to obtain results for it, you need to run the analysis again.
