Analysis assumptions adopted in the Structural Analysis application.
This application 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 Floor and Wall
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)
Analytical links between Beam and Column
Boundary conditions (analyzed as supports)
Releases for Column, Beam and Bracing
Load Case and Case category
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.
The model self-weight can be included automatically in the analysis; to do it, select the Add to existing load case option under Self-weight options in the Analyze in Cloud dialog (see Performing the Analysis).
NoteOnly the self-weight of the analytical model uploaded to the cloud is included in the analysis. However, it may differ from the self-weight of the physical model in the Revit project (see Structural Analytical Model Overview).
Envelopes. When uploading the model to the cloud, 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.
After adding a new load combination, you need to run the analysis again to obtain results for this combination.
