Analysis class options and colors

Use the options in the Class list on the Analysis tab in a part’s analysis properties dialog to define how Tekla Structures handles the part in the analysis.

The option you select in the Class list determines which tabs are available in the analysis part properties dialog.

When the advanced option XS_AD_MEMBER_TYPE_VISUALIZATION is set to TRUE (which is the default value), you can show the analysis class of parts using the following colors in the analysis model. You can also indicate the analysis classes using different colors in the physical model.

The analysis application you use may not support all of the following options. For example, the Truss options are not available with Tekla Structural Designer.


Option	Description	Color
Beam	Line object of two nodes. Part can take any load, including temperature.	Blue
Beam - Truss	Part can only take axial forces, not bending or torsion moments, or shear forces.	Bright green
Beam - Truss-Compression only	Part can only take compressive axial forces, not moments or shear forces. If this part goes into tension, it is ignored in the analysis.	Yellow
Beam - Truss-Tension only	Part can only take tensile axial forces, not moments or shear forces. If this part goes into compression, it is ignored in the analysis.	Pink
Beam - Ignore	Part is ignored in the analysis. Self-weight load is taken into account if you have set Generate self weight load to Yes on the Loading tab.	Part not shown in the model
Column	Vertical line object of two nodes. Modeled from bottom to top. Part can take any load, including temperature.	Blue
Column - Truss	Part can only take axial forces, not bending or torsion moments, or shear forces.	Bright green
Column - Truss-Compression only	Part can only take compressive axial forces, not moments or shear forces. If this part goes into tension, it is ignored in the analysis.	Yellow
Column - Truss-Tension only	Part can only take tensile axial forces, not moments or shear forces. If this part goes into compression, it is ignored in the analysis.	Pink
Column - Ignore	Part is ignored in the analysis. Self-weight load is taken into account if you have set Generate self weight load to Yes on the Loading tab.	Part not shown in the model
Bracing	Line object of two nodes. Part can take any load, including temperature. For parts whose analysis class is Bracing, Keep axis position is off by default.	Green
Bracing - Truss	Part can only take axial forces, not bending or torsion moments, or shear forces.	Bright green
Bracing - Truss-Compression only	Part can only take compressive axial forces, not moments or shear forces. If this part goes into tension, it is ignored in the analysis.	Yellow
Bracing - Truss-Tension only	Part can only take tensile axial forces, not moments or shear forces. If this part goes into compression, it is ignored in the analysis.	Pink
Bracing - Ignore	Part is ignored in the analysis. Self-weight load is taken into account if you have set Generate self weight load to Yes on the Loading tab.	Part not shown in the model
Secondary	Line object of two nodes. Part can take any load, including temperature. For parts whose analysis class is Secondary, Keep axis position is off by default. Secondary parts snap to nearest nodes instead of part end nodes.	Orange
Secondary - Ignore	Part is ignored in the analysis. Self-weight load is taken into account if you have set Generate self weight load to Yes on the Loading tab.	Part not shown in the model
Wall - Shell	Part can take any load, except temperature.	Aqua
Wall - Plate	Same as Wall - Shell but plate elements are used in the analysis application.	Aqua
Wall - Shear wall	Part can take lateral forces and vertical forces.	Aqua
Wall - Ignore	Part is ignored in the analysis. Self-weight load is taken into account if you have set Generate self weight load to Yes on the Loading tab.	Aqua
Slab - Shell	Part can take any load, except temperature.	Aqua
Slab - Plate	Same as Slab - Shell but plate, membrane, or mat foundation elements are used in the analysis application.	Aqua
Slab - Membrane
Slab - Mat foundation
Slab - Rigid diaphragm	Only applies to parts parallel to a global xy plane. Filter: Nodes that belong to a part matching the filter will be connected with rigid links which together affect displacement. For example, you can use a column filter to connect only column nodes to rigid diaphragms.	Lilac
Slab - Ignore	Part is ignored in the analysis. Self-weight load is taken into account if you have set Generate self weight load to Yes on the Loading tab.	Part not shown in the model
Contour plate - Shell	Part can take any load, except temperature.	Aqua
Contour plate - Plate	Same as Contour plate - Shell but plate or membrane elements are used in the analysis application.	Aqua
Contour plate - Membrane		Aqua
Contour plate - Rigid diaphragm	Only applies to parts parallel to a global xy plane. Filter: Nodes that belong to a part matching the filter will be connected with rigid links which together affect displacement. For example, you can use a column filter to connect only column nodes to rigid diaphragms.	Lilac
Contour plate - Ignore	Part is ignored in the analysis. Self-weight load is taken into account if you have set Generate self weight load to Yes on the Loading tab.	Part not shown in the model
