You can define which objects to include in an analysis model. Tekla Structures includes or ignores some objects automatically.

The following factors affect which objects Tekla Structures includes in analysis models:

• Analysis model filter

• Analysis model content

• Which objects you select, add, remove, or ignore manually

Tekla Structures ignores the following objects in the analysis, even if you have included them in an analysis model:

• Parts and loads that are filtered out

• Component objects, such as minor parts, bolts, and reinforcing bars

• Parts whose analysis class is Ignore

• Parts whose analysis part has been deleted

The following components set the analysis properties of the parts they create, so these parts are included in analysis models:

• Shed (S57)

• Building (S58) and (S91)

• Slab generation (61) and (62)

• Truss (S78)

For example, the vertical and diagonal parts created by Truss (S78) are handled as braces in the analysis.
