Materials

The Materials table in the “Aluminum Design” category lists all the materials you have created in the model.

Valid Materials

Aluminum Design is linked to materials of the Aluminum type. The font color of the materials provides information about the use and allowability of the material. The colors mean:

  • Red: Material is not suitable for aluminum design.
  • Blue: Material is not used in the model.
  • Gray: Material is not used in the objects to design.

Info

Only materials of the "Aluminum" type are allowable for the design: All necessary design properties are stored here (see also the chapter Materials of the RFEM manual).

Objects that have been assigned an invalid material are not included in the calculation, even if the "To Design" option is activated for this material. They are automatically marked as "Not Valid / Deactivated" in the Objects to Design table.

Removing Materials from Design

For a valid material, you can exclude all objects with this material assigned from the design by deactivating the “To Design” check box. These objects are then classified as “Not Valid / Deactivated” in the Objects to Design table and are not analyzed during the design.

Adjusting Material Properties

If you want to use user-defined strengths or partial safety factors for aluminum design, you can adjust the material properties: Double-click the corresponding table row or use the button in the table toolbar to open the material editing dialog box.

Activate the User-defined material option in the “Main” tab. This allows you to edit the material properties. In the “Material properties” tab, for example, you can change the stiffness of the material and the strengths in the individual thickness ranges.

In the “Aluminum Design” tab, you can adjust the partial safety factors of the material for design according to the selected standard, for example, γM0 and γM1 for EN 1999.

Important

The factors for stiffness modification defined in the “Edit Material” dialog box or in a structure modification are not taken into account in the design checks in the Aluminum Design add-on. Use the adjustment of material properties for this purpose.

Options

The symbols in the “Options” column represent various settings or modified values. They allow for a quick overview, for example, to identify materials with customized properties.
