Decompose panel loads

Tip: Although Tekla Structural Designer carries out load decomposition automatically when you click to analyze the structure, you have the option to decompose loads manually by using the Decomposition command.

In the context of big or complex models, decomposing manually can potentially save time, as it allows you to check that panel loads have been decomposed as you intend before running the analysis.

Decompose panel loads for an individual construction level

Open a 2D view of the desired level.
Click the '2D' toggle button at the bottom right corner of the view to display it in 3D.
On the Load tab, click Decomposition.

Tekla Structural Designer generates an FE mesh within the two-way slab panels, and applies the resulting decomposed loads to the supporting members.

Tip: In case you cannot see the changes in the model at this point, ensure that you have selected the correct settings in Scene Content - See View decomposed loads below.

Decompose panel loads to all required levels

Open the Structure 3D view.
On the Load tab, click Decomposition.

Tekla Structural Designer generates an FE mesh within the two-way slab panels, and applies the resulting decomposed loads to the supporting members.

Tip: In case you cannot see the changes in the model at this point, ensure that you have selected the correct settings in Scene Content - See View decomposed loads below.

View decomposed loads graphically

Open a 3D view of the model, or a 2D view displayed in 3D.
In Scene Content, go to Loading.
Select the Decomposed option.

According to your needs, do one of the following:

To	Do this
View the decomposed load values	In the cell on the right side of Decomposed, select both Geometry and Text.
View the decomposed loads without load values	In the cell on the right side of Decomposed, only select Geometry.

In the Loading list, select the loadcase.

Note: Decomposed loads do not exist for 2-way slab items at levels where the Mesh 2-way Slabs in 3D Analysis option has been selected.
At levels where this is not the case, you can view the decomposed loads. However, you cannot see any shell results from the FE load decomposition.

View applied and decomposed member loads in a table

Open a 3D view of the model, or a 2D view displayed in 3D.
Right-click on the member, and from the context menu select Show Member Loading.
Loads that have been applied directly to the member, and loads that have been decomposed to the member are displayed in a table. The 'In Proj.' checkbox is used to indicate applied loads applied in projection as opposed to along the element.
To filter the data by Loadcase, Source, Direction, or Type:
1. Click the appropriate column header to filter by (Loadcase..., Source..., Direction..., or Type...)
2. From the drop list that appears clear the categories that you don’t want to be displayed.
3. Click the Close button under the drop list.
